Brian Cox - What Was There Before The Big Bang?
Brian Cox - What Was There Before The Big Bang?
Physicist and professor of particle physics Brian Cox explains hypotheses about the causation of the big bang. Brian Cox is a brilliant scientist who makes complex cosmological concepts like the big bang way more easy to understand.
In the beginning, there was an infinitely dense, tiny ball of matter. Which started to expand and would eventually give rise to the atoms, molecules, stars and galaxies we see today.
But what was there before the big bang? What was the state of the universe before...Well, everything?
Brian Cox explains how inflation fueled by a mysterious form of energy that permeated empty space itself, left the universe desolate and cold. And only after that did the hot, dense conditions of the Big Bang emerge.
If cosmic inflation correctly describes what happened before the Big Bang, it may push the ultimate answer to the question of where we came from beyond the reach of science.
Brian Cox also mentions alternative theories to cosmological inflation which tell us what caused the initial conditions that would eventually give rise to the big bang.
The twin pillars of modern physics are Einstein’s General Relativity and quantum theory.
To understand how the big bang emerged and what came before it, it is essential to unite Einstein’s theory with quantum theory.
The most distant objects in the Universe are 47 billion light years away, making the size of the observable Universe 94 billion light years across.
If you are wondering, how can the observable universe be larger than the time it takes light to travel over the age of the Universe? The answer is because the universe has been expanding during this time.
And this causes very distant objects to be further away from us than their light travel time.
Most scientists think the entirety of the universe extends way beyond the observable universe. But is there anything beyond the entirety of the universe?
Brian Cox also explains if there is anything beyond our known universe and how it will "end".

You can witness exponential inflation right here in the UK. It's pretty scary.
Oooooh aren't you edgy.

Sucks to drive to work farther every day.
What’s scarier is when I went back to the UK & fish & chips weren’t served in a newspaper 📰 😮🐟 🥔
I can’t help but wondering about further and further back and the question that’s always asked; why is there anything at all? And this question; Is it possible for there to be nothing? Possible for there to be no universes? Also, possible for whatever brought about the universes to not exist. My brain breaks with the infinite regress.
Lawrence Krauss, American Physicist, believes that something can come from nothing. Worth reading some of his thoughts.
i stopped trying to think about those things, i just cannot handle it mentally.
The problem of infite regress stops and you gain peace when you accept that there must be an uncaused being that causes everything else.
We have to accept that we will never be able to find the answer about the creator. But we have enough evidence to believe that there is someone outside of all this space and time who created all this. The almighty God.

I am 76 and astronomy has changed so much since then. My dad was one of the original Stony Ridge Observatory members. I went to all the meeting with him over the years while it was being built guided by George Carroll. Since we have had major telescopes in space and especially now our knowledge of reality of what is really going on is incredible and far beyond what was known back then. This certainly made me think again. Thanks. As Steve Morris, of high horsepower engines says, "Danger, Watch this and you might learn something." So glad to learn.
I’m 46 and it’s changed so much ! 😂
I believe the more we discover about reality, the more we realize how much more there is discover, and how little we know. For every answer provided by the discovery, has produced more questions, than questions answered.
just the fact that were aware enough to ask these questions is amazing in its self.what a species!!!
And somewhere in the galaxy is a species that looks at us and wonders how come we haven't even set foot on one of the other planets nearby.

I am always amazed when I learn of nearly incomprehensible Cosmic events like the start of our universe. It's enough to make me wonder why "intelligent" life that was gifted a planet with all the resources needed for survival could be so petty as to fight amongst ourselves the way we do. What a gift we humans were given so long ago.
I agree and yet, so many people just throw their lives away for no reason.... I don't think most people realize how lucky we are
It's mind-boggling to say the least, how did the universe even begin? It still had to come from something, and before something was nothing, but before nothing, there's always something

It's all a dream, we and everything around us is just a dream. We are not the dreamers though, we and everything that we think is real are part of the dream, we are the dream. Anything and any possibility can happen in a dream. The big question is who or what is doing the dreaming
Mate, I reckon that I've got close to being institutionalised, thinking about this stuff. Well, honestly, it could have been spending 26 years with the same woman, but either way, I am amazed at how I ended up at this point.

It is god my friend.
This is infinitely frightening and awe inspiring all at once.
These types of videos make me start sobbing and I can’t quite explain why
Don't cry, dry your eye. I heard it in a song.
It's really weird sometimes to be sat at my computer, and be immersed in whatever I'm doing, and suddenly remember space is out there. I mean most things in day to day life you could say are fairly mundane, but space is almost cartoonishly wacky in its immensity and mystery, and its right there in the sky. We should all be going around with our eyes out on stalks over how ridiculous it is, but we just kind of get used to it and it only seems amazing every now and then when we actually think about it. Another funny thing is that most animals don't even know about space, like for example dogs, they don't think much beyond the general area that they're in, and they will never look up at the stars and question what's going on up there. It makes me wonder if we do the same, and we just don't realise it - maybe we just cannot get over the human condition enough to truly understand it, maybe there is something, that to some aliens, is obvious, and we just can't see it. I guess it's possible that AI could break through this, and figure things out that we hadn't considered.
The sad thing is there’s a lot of people who believe they’re here to destroy others, in the insane belief of their superior religion or culture, which tells me they lack the freedom to think, learn, wonder & question with the available knowledge in science & technology. But would they still have those beliefs if astronomy news was an equal part of every culture, like it once was for most? Would todays “woke” activist culture be as focused on being offended by, just about any petty topic, if they looked through a telescope or understood our position in the galaxy & universe? Unfortunately, the more western countries rush to diversify, our empathy is more easily exploited, resulting in less freedom of expression, a fear to question anything, slandering fact as evil, to lower our intelligence for easy compliance. In Australia, our government has failed to explain the fact that Australia Day has nothing, whatsoever, to do with the first arrival, which was April 1770, to explore & mark the transition of Venus in Southern Hemisphere. Jan 26th was chosen as a celebration of the Aussie flag for new & indigenous Aussies, to unite as a new settled country. There was good & bad, as in most beginnings. Life should have a balance to evolve. But there’s no way Australia was going to remain unsettled. Exploration was/is a natural human fact, like unconscious bias is part of every living thing in order to survive & not some problem to be treated. I’m lost & rambling, so on with this epic fails video?😳
I totally agree. I can go a year without ever really looking up at the sky at night, and then all of a sudden I do, and see all the stars and constellations, its breathtaking. Living in a city probably doesn't help.
I can't worry about space when I'm wondering if I'll even have a place to live next month.
Earth is friggin amazing. We take it for granted. Life is a gift. Hopefully when we pass from this earthly life onto something else, we will get to understand it all.
@@justinbennitt835 I used to think that, but frankly I wouldn't be shocked if there really is something after death. Not claiming that there is of course. I just consider this existence I am experiencing right now to be so surprising and whacky, that just existing again doesn't seem to be that unlikely to me in comparison. If something showed up once, then surely the chance for reappearance is greater than the first time. Also, I fear existence more than death nowadays, so I am kind of fearful that we can never truly die. Not to mention that AI could figure out a way to revive us, so I am dreading that as well.
This is the stuff that kept me up at night as a young boy. If there was a beginning of the universe then what was before, etc. Good job Brian!
There were no before .... time in our dimension begin there at that point ... or do you consider that time is forever and has been since ever? ... if an higher dimension, time could be "circular", "someone" in a higher dimension could see the "all" time like we see the "all" in 2 dimensions
@@gafrancisco forever or for ever, very subjective. To live forever? is that imortality or living from the start of "time" to the end of "time"? And is it subjective? Enquiring minds want to know! And is time not a Human construct to let us move in some way through the universe/existence/reality? It could by cyclic, but I think we have 3D licked, but the fourth? Time? If there was no before when did it start, and if it started what was before?
The universe started an infinite long time ago. With an infinite universe we live in, there was and infinite amount of mass At the beginning, *infinite mass = infinite gravity = infinite time. Simple. This statement only answers the question of when all this universe started. Infinity is not just a big number. This does start to explain what caused the inflation 13.8 B yrs ago
@@gafrancisco If matter came from something then that is what he is refering to. It existed before regular matter did, and no amount of mental gymnastics can get you to remove it. Unfortunately for you
Hehe, with me the question was always: what's after the universe because everything has to have an "end" and then... What's after that, ect, ect. This plagued me my whole childhood and obviously still does 😂👍
Professor is nice to talk about all these theories . At the end of the day you’ll never reach a definite answer . It is mind boggling to try understand the enormity of the universe . I’m an open minded person and the question keep coming up who’s is mighty this mighty force managing the whole thing .
An old man with long white beard
No force at all. There is no management. Listen more closely: Cox says one of the possibilities is that there is an infinite number of universes. Hence every random possibility is realized.
@@damijanxxx7221 that’s weird. Almost done reading the Bible, not once did I hear anything about a man with a beard in the sky 😂
"I’m an open minded person and the question keep coming up who" WHO? You're not open minded at all, you've already made up your mind to go with the lies.
Love to listen to the wisdom of Brian Cox. The clue to answering this very important question he is discussing is a related question. Q: "If the Universe is expanding, what is it expanding into?" The answer to THAT question is one of the many puzzle pieces that Humankind has available about the construction of our Universe. I have a theory that I've never heard or read before but may make sense to Mathematicians and Physicists. The Theory is that that "There is a 4-Dimensional realm into which our 3-Dimensional realm is expanding into." The basis for this theory is that a "Universe" is a closed realm containing objects and energy whose behavior may be described using mathematical Constants and Formulas. The primary assumption for this theory is that a 1-dimensional universe may exist within a 2-dimensional universe but not vice versa. IOW, a 3-dimensional universe cannot exist in a 2-dimensional universe but may comfortably exist in a 4-dimensional universe. For example, the *constant* PI (3.14159..) has a meaningful value in 2-dimensional mathematical space, 3-dimensional space, and (by extension) also in 4, 5, 6, 7..N-dimensional space. Additionally, Triple Integrals, nor formulas for the Volume of an object, have any relevance in a 2-dimensional realm. By extension, in a 4-dimensional universe, not only are Triple Integrals, and constants such as PI, relevant, but there are NEW 4-dimensional constants and formulas yet to be discovered. (Note: some may consider TIME a "dimension". However, Time is NOT a mathematical dimension but instead, much like Gravity, is an *effect* that is created by the presence of mass and energy in multidimensional space). In other words, our 3-dimensional universe is expanding INTO a 4-dimensional universe that is in turn expanding into a 5-dimensional space..ad infinitum. The details of this theory are too extensive to be described here and the concept of a 4-dimensional universe may be a bit strange for most to understand, however Humans interested in the concepts of universes within universes should definitely read the book "Flatland: A Romance of Many Dimensions" (1884) by author Edwin Abbott Abbott. You will see further after reading this book. So, if we can understand what our 3-dimensional universe is expanding INTO, then that will lead us to a better understanding of the question "What was there before the Big Bang?" As a BONUS, the answer to the question "What is our Universe expanding into?" may also help us understand the nature of Black Holes and WHY they exist. I believe that our 3-dimensional universe is somewhat POROUS and there are "holes" in our universe's "outer shell/skin" that allow our 3-dimensional universe to "leak" energy and matter into a lower 2-dimensional universe. Similarly, Quasars (or other energy phenomenons) may be "holes/spouts" that "leak" energy from a higher energy 4-dimensional universe INTO our 3-dimensional universe. Something to ponder. Gnome sayin'?
I am so intrigued by science videos from Brian, Neil, and others that make me wonder even more about this giant floating bubble we get to ride on every day and everything surrounding it... but its like nighttime soft music to my ears and can somehow put me right to sleep. I wake up and rewatch immediately, just to have it happen again. Sometimes it takes me like 5 or 6 times to manage to get thru a whole video. I love and hate it all at the same time.

How can there no end to the universe? It must go on forever up, across and down. But how? Mind,-boggling. Love Professor Brian Cox for making us so interested. In our universe.
I think most people (including scientists) dismiss just how mind-boggling an infinite universe is. Especially considering the infinite can never be observed other than within mathematical expressions.
There is no up, down or across. There is also no such thing as time. These are all human constructs to enable us to perceive the universe in a way we can understand. If there were no observers in the universe then time and space would not exist as we know it
@@TheUkdan02 that’s exactly what I’ve said about how time only exists to us because it’s just a tool to keep track of what we as humans are doing but time isn’t a real thing.
@@TheUkdan02 yes. I like the theory of biocentricism, whilst we cannot prove it or indeed any theory, it makes more intuitive sense than the something out of nothing Big Bang.
Something that begins to exist cannot be "infinite". By the second law of thermodynamics the universe will lead to heat death and thus cannot be infinite.
Fascinating. I remember reading a book about COBE (1989 to the 90's) some 25 years ago and the struggle to achieve the low temperature (near 0 kelvin) to measure the cosmic background radiation. It was an interesting read as it was quite technical in nature, worth checking out.
CMBR: (Cosmic Microwave Background Radiation): Consider the following: Per QED (Quantum Electro Dynamics, whereby 'em' interacts with the electrons in atoms and molecules) and QCD (Quantum Chromo Dynamics, whereby 'em' interacts with the nucleus of atoms), matter has to exist for 'em' to be given off by that matter. What matter exists in outer space for that microwave 'em' to be seen by us? And 'if' it were from when matter first came into existence during the fairy tale of the 'singular big bang', that 'em' should be long gone by now and should not even be able to be seen by us.
Common sense says if there was a big bang and everything was blown out from it then there must be a massive space left in the universe? Why hasn't that been found?🤔
@@superdinkydoo Who's common sense says this?
Where ever you start these theories "in the beginning" it always leads to the question - how did that come about, how did it get there and what was there before that. It's mind blowing thinking.
Philosophically it's rather easy: 1st you have to apply ´Sets Theory´. Assuming our Universe is a subset of another one larger / older, ours would be bound to *all* the rules / laws of the enclosing one, plus 1 or more additional rule. So let us assume, for instance, that ours is the 1st in which Conservation of Energy and Mass-Energy Equivalence appear. We have now a whole new set of Universes that can give birth to others without any requirement. They simply pop. So again, using Sets Theory, it's plausible to assume that if at some point there was no Universe at all, therefore there was also no Conservation of Energy, Mass-Energy Equivalence and Causality requirements
I have this thought that the universe is always expanding and shrinking and restarting every time. From a singularity to a very big expansion and again shrinking to a singularity that expands again. Edit: since the space and time are relative, if space started contracting (opposite of expansion) time will start going the opposite sens getting us back to origine of the universe again
Accelerating expansion never really seemed confusing to me. If you have regions of space expanding, creating new regions of space that in turn are expanding, rinse and repeat, you would very quickly (in the scope of the age of the universe) end up with an exponentially compounding expansion rate that, while it’s influence on tangible matter might be minimal, the sheer volume of new space and that space expanding would conceivably push things away faster than the speed of light even though the objects themselves are still only moving through the space ahead of them, not the newly created space compounding behind them. They’re not moving faster than the speed of light, new space is being created in between us and them in all places at all times causing the illusion of faster than light travel

As i approach 73 i recall that i asked this question of my dear mum, she said " there are some questions we do not ask !" I've kept the faith with that answer, as when i think about it i go blank !
questions are out there to be asked :)
As a kid I read about shadow reality/dimensions in a Dutch magazine called Kijk (Look). If remember correctly it was when collided nothing would exist (matter + anti matter). This was how the big bang was explained in the 1980's.
Great vid! I have questions... We are constrained by certain limitations in our universe, such as the speed of light, at app. 300K km/s. As Brian pointed out, the inflation period lasted a mere fraction of a second, expanding from the size of an atom to the present observable universe. I am pretty sure that would be many times the speed of light... Perhaps that was because the forces in this universe weren't fully installed yet at that point in time? And that leads to more questions, such as why do the forces of nature have the properties/constraints they have, and why/how could they be different in another universe?
Inflation ended when the universe was about the size of a grapefruit, it was just very badly explained in the video...
Superluminal expansion of space/time is allowed.

This is such a based comment. We look back on people a thousand years ago and think, "What dumbasses." If there are still people around in another thousand years, they'll look back at us and think, "What dumbasses," too. The question is whether we will be like the shark or the T-Rex.
There are species on the planet that have been around for millions of years, like sharks and crocodile, virtually unchanged for eons.

. Another amazing video from an amazing scientist. I read someone say that Brian Cox could be the next Carl Sagan. It is clearly implied here that space and time are emergent properties. Causality does not seem to have been mentioned specifically, but if time and space are emergent, then by inference causality too is an emergent property. Also said, we might never ever know what happened “before” these emerged. But what does “before” actually mean if time started with big bang… I have heard is said - “Truth is that from which all words and languages bounce back in silence!” Thus 3 Questions that science cannot ask, leave alone answer - - What was ‘before’ time - What is ‘outside’ space - Why causality Because science can start after these three are available. (Donald Hoffman - “give us a few miracles and we scientists can prove anything”). So then, what is THAT from which these emerged? What is THAT “Ontological Primitive” ? Then again, 20th century has shown us that what we perceive as the universe is : - - Uncertain - Relative - Incomplete Thus, we have 2 Question that needs to be asked. - What is that from which Time, Space and Causality emerged? - Is there anything which is certain, absolute, complete ? People from a few thousand years ago have speculated much on these questions, and they proposed some amazing questions and claims. Like, - For something to be Real, doesn’t it need to be Certain, Absolute and Complete. - Then can an entity that is Uncertain, Relative, Incomplete be said to be Real. Thus don’t we have to say the Universe is not Real in any Absolute sense. - Then what is Real ? - Time, Space and Causality are emergent entities. Then logically there has to be that something, an ontological primitive from which these emerged. - What is That ? - That is the Real, from which time, space and causality emerged. That is the Ontological Primitive. They call it by a name which means like “Vastness”. - Universe is the consequence of the emergence of Time, Space and Causality. - If the Universe is “not Real”, then how do I experience it? Doesn’t it ‘Appear to me’ ? - Yes, it is an Appearance in the Real, which is here for some time and will dissolve back into the Real. - It is not that “the Appearance is here, and Real is something long ago or in a faraway galaxy”. Appearance is experienced in the same locus as the Real. - Real cannot be experienced as Real, because our sum total of experience is via instruments of experiences like the senses and mind. These instruments are tuned only for use in survival process. Thus as far as experiencing the Real is concerned, the instruments are limited hence defective. - Thus, only Appearance can be experienced via senses and mind. - Appearance is just the experience of the Real when experienced via the defective instruments of senses and mind. - Experience of Appearance itself is the result of the Error from the defects of the experiencing instruments. - If Real can ‘Appear once’, it can Appear infinite number of times and infinite number of places. - But once you say infinite, then ‘number of time’, ‘number of places’ becomes meaningless as you cannot count or locate infinity. Then there is only ‘Infinitude’. - Infinitude implies just One, which cannot be created / grow / change / evolve / deteriorate / destroyed. - Thus, That would be One Without a Second. - How to experience That ? It cannot be experienced by senses or inference. It can be only ‘Realised’ as a fact once the Error is understood as a consequence of defective instruments. If modern scientists agree to look beyond the conventional methods of logical positivism, at other available ideas and claims, it could help a lot for a better understanding of things. Many have done it, but I guess as persons, not as a concerted fomalised effort of the scientific community. IMHO. .
Carl Sagan wouldn’t be a gullible idiot like Cox during the plandemic. I wonder if he is apologizing to the “conspiracy theorists” yet. He will probably not mention it.
Look, I had enough trouble getting my head around the video ( which I'm not sure I did!). Don't befuddle me even more 😂
Thank you very much. You made it happen once again. My head exploded.
It’s so refreshing to hear brilliant and honest minds state that they simply don’t know some things about the universe.
This fits with Roger Penrose’s idea of a cyclical universe, where the universe doesn’t know how big it is once all the matter is gone and time essentially ceases to exist. The idea that it would be expanding exponentially at that point has a nice symmetry with the concepts around the big bang.
This is the End of Times. All the universes are being rectified to their original semi-divine state.
Just to put this theory into its most simplistic terms, a Big Bang occurs, the universe stretches, a Big Bang occurs and so on?

To my mind the most interesting question. Are we in a universe that will generate life capable of fully understanding all of its secrets? All we can really conclude just now is that we are trying. But what we do know is that solar systems that are capable of supporting life have a finite life, so perhaps our single most important challenge is to work out how to find and move around such systems.

THE ETERNAL QUESTION, AND A GOOD ONE!
Would it be plausible to assume that given enough time the rate of expansion and the space between galaxies will increase to match the expansion speed of the space before the big bang creating new big bangs within the new gaps between the mater that exists currently. Let's say 20 or 30 billion years into the future for instance once the galaxies we currently know of have expanded outside their horizon. If space expands faster than light eventually no galaxies would be able to see light from another and would be isolated. But that space between continues to expand. Would that not create the same conditions as proposed pre big bang space?
Essentially creating a self refilling universe. That grows exponentially and can house multiple big bangs within the same universe.
Anyone remember the scene from a MIB a movie where a universe is inside of a small marble attached to a necklace on a cat? It slowly zooms out to show the grand scale from being on a planet to showing the planet from space, then the solar system, then the universe and then shows that it was all inside the necklace.

I have no formal education in the subject , but I had a question. Based on my understanding, if energy can’t be created or destroyed, based on the laws of conservation of energy, then how would the “universe” have started smaller then the size of an atom and exponentially inflated to what it is today? Wouldn’t that mean that all of the energy of the current state of the universe was contained in a space smaller then an atom prior to the Big Bang? Is that possible, and if it is, why was there an event such as the Big Bang that happened when the same amount of energy existed for as long as we know.
When you are an expert physicist you can imagine the reason in your head, but it's hard to put it in words. Also we have absolutely no idea

@@zachsmith5515 Would that be the "theory" part of "theoretical physics"?
I think it is too early in timespace to declare what the fate of the universe is. I think it is far more likely that the absolute energy state is >1, even by very low percentages, which would mean the universe would be spherical and eventually massive enough to have let the entropy slow down the expansion of space (given there's not enough time for the expansion of space to be manifested in reality) to let gravity take over and trigger a crunch/bounce under its own countably infinite weight. Or maybe the toroidal theory is the right one, I think that's a brilliant one too.
I watch these videos hoping that eventually one of them will actually give me “the answer”. The “wonder of space” is that we wonder what the answers are and will likely never know. We may not even be asking the right questions. Fascinating.
do we even move or does everything else around us move? I’m starting to believe that I never moved in my life. Even as I walk I’m rly not moving in reality. My body seems to be making some movements and my surroundings move but I never truly move
If could ask questions it would be.. If the universe is always expanding, where are we? When we detect the background radiation reaching us, are we looking forward in the direction of expansion, or behind, towards the origin? Or everywhere in 24 hours as the Earth turns. Which would also relate to the Earths position as it orbits the Sun. Basically, are we able to look forwards and/or backwards.
@@carraw3501 great question
Don’t worry about Brian and the Big Bang. They didn’t tell you that the very same Hubble who they say was a big supporter of the Big Bang...wasn’t! Because the record shows that in 1929 Hubble knew “expansion” was not real. Here’s the real story: “Hubble concluded that his observed log N(m) distribution showed a large departure from Euclidean geometry, provided that the effect of redshifts on the apparent magnitudes was calculated as if the redshifts were due to a real expansion. A different correction is required if no motion exists, the redshifts then being due to an unknown cause. Hubble believed that his count data gave a more reasonable result concerning spatial curvature if the redshift correction was made assuming no recession. To the very end of his writings he maintained this position, favouring (or at the very least keeping open) the model where no true expansion exists, and therefore that the redshift "represents a hitherto unrecognized principle of nature". This viewpoint is emphasized (a) in The Realm of the Nebulae, (b) in his reply (Hubble 1937a) to the criticisms of the 1936 papers by Eddington and by McVittie, and (c) in his 1937 Rhodes Lectures published as The Observational Approach to Cosmology (Hubble 1937b). It also persists in his last published scientific paper which is an account of his Darwin Lecture (Hubble 1953).”

I love the way he explains things I'm a lay man but every time I listen to Dr Cox I understand what he's explaining .
I also like that he actually presents theory as theory & not fact.
Question: can particles move faster than light? It sounds like the video is saying during the Big Bang, expansion happened faster than light. From what we know today, can that happen?
There is no limit to how fast space can expand. Space can expand faster than speed of light. So you can increase the distance between two particles many times faster than the speed of light, but that doesn't mean they are traveling faster through space than the speed of light.
There had to be a beginning, and there has to be an end...but we will never know..... Embrace the life we were given, it only comes once, and it is precious.

Something i've never understood is what the early universe was expanding in to soon after the big bang..into empty space? If so, does that mean empty space existed before the big bang?

There was no “before” the Big Bang because to have a “before” you have to have time and the concept of time only exists within our universe, which only exists after the Big Bang. So you have to theorise what existed in a condition that is impossible to understand because the rules that apply to our universe did not exist.

Just because the concept of time is a concept, doesn't mean that there wasn't anything before. The word before still means what it means.
The singularity theory would require graphs to explain it better but its also not a fact… from what Crash Course said, think about the distance of your thumb and all your fingers. Close your hand, then open. The distance of each finger will expand further away from your thumb or shorter, depending on the which finger you’re finding distance at. & we can now see the “wall of fire” (think of a hot, dense, soup) which is 13.8 Billion light years away (really 40 now because of expansion). That, is the Beginning of the universe. The wall of fire though is too uniform for the Big Bang to have came from a singularity, and had it came from one, we wouldn’t get the same results we have today of the universe. Awesome video !
I realise that most of the images and animations accompanying the voiceovers are more cosmetic than informative, but from 4'05 there is a time-chart showing the Big Bang preceding Inflation, while at the same time Cox explains that "it is mainstream" theory that the Big Bang came after Inflation. The same thing happens near the start of the video. Can anyone explain this inconsistency?
I'd have to listen again, but did he not say that the Big Bang came "immediately" after inflation?
@ David: Yes, I noticed this, too. What he says about the Big Bang happening _after_ inflation (or, if you like, inflation occurring _before_ the Big Bang) makes no sense and is contrary to everything I've ever heard about the Big Bang theory. It doesn't even make sense. He seems to be saying that inflation occured before the Big Bang and that inflation resulted in the universe being its present size as it is today. Huh??? As I said, that makes absolutely no sense. I simply reject those statements as being incorrect, or at least illogical and contrary to everything that everyone else has ever said on the subject. I gave the video a thumbs-down. 👎

The concept of beginning or end are ultimately objects of our perception, they are mere conventions derived from it. There is no beginning, nor there is an end. There is. Same as when you try to think of the most fundamental unit of something, everything is made of something. There is a universe in everything.
Sometimes they demonstrate gravity with a heavy ball, like a bowling ball, on a rubber membrane. Then a lighter ball, like a tennis ball, is placed on the membrane and when looking down from above the balls will behave as if they had gravitational attraction. We've all seen that, right? Now imagine there is a fluid under the membrane, something that cannot change volume. The bowling ball will push the membrane down locally, but further away it will push the membrane up. Maybe dark energy, the accelerating expansion, is caused by a similar mechanism.

if the universe expansion is accelerating, would that eventually reach another inflation phase once the expansion get fast enough ?
the big bang could be simply a stage in a never ending cycle of universe after universe.
Yep, though that just raises further questions. As does every answer and theory.
Maybe...but there would have to have been a 'first big bang' wouldn't there? How/why did this happen? Where did the energy come from? Did there exist other dimensions before the physical spatial dimensions? Was the first big bang 'God' clicking his fingers from the 7th dimension? Why something instead of nothing?

I Like the idea that the big bang was the moment our region of the universe entered a black hole. The beginning is too hot for atoms and extraordinarily dense. As the black hole expanded everything cooled unpacked and began building again.
As much as I appreciate all these theories, I have always thought the big bang from a singularity is incorrect. Extrapolation can sometimes take a chaotic turn, and the before BB is becoming questioned more, which is great! My belief is that this question will never be answered, only speculated upon.

Just my opinion...thanks to any one who reads this rambling message!!
Try explaining a computer, the internet to Horatio Nelson, we should be grateful for people such as B. Cox for explaining as simply as is possible things beyond the capacity of most of us to instantly grasp, what was before the singularity is for Cosmological physicist, astrophysicist, mathematicians, and way beyond the capacity of most of us, we should be grateful we are all educated to not just accept everything came from a magical entity. Most of us trust science because we know it's our best hope, it's why we visit a doctor when we do not feel well and not pastor Joe blogs.
The big bang from a singularity does appear to be incorrect. The current theory is that the big bang was very dense, but not a singularity. It is not so much the limitation of the mind, but rather than limitation of evidence. We may come up with many theories, all of which fit all of the available evidence, but the evidence you need to determine which theory is the correct one is no longer available.
@@derekardito2032 Thanks, I love science and what it has done for mankind in all its guises. Unfortunately I still believe that the creation of the universe can never be answered with empirical proof by anyone now or in the future, only postulated upon, and best informed theories! I dislike it...but sometimes it is best to let some things go!
@@seeaan5729 there is I firmly believe an answer to everything, sure us of today are no where near answers to most things, look how long since man first graced the earth how how little of the much we gave discovered, I agree that empirical evidence alone will never prove creation, if indeed creation did at any time occur, and there is zero evidence it did. I don't think we can quite get our heads around something not having a begining or an end, but everything we do know that had a begining was made up of things, the raw materials of what the craftsmen made their product from. We even know today the amino acids that make the materials of life, our research into biology our species has progressed more in the last century that all the millenniums added together before, nothing but nothing is best left alone, not leaving alone has produced and prolonged our lives, from hygiene science, to cures for diseases once thought the possession of spirits, religious beliefs hold back the advancement of science, belief in things with no evidence, holds us back. Superstitions, groundless fears, our ability to imagine so wonderful to entertain us, so frightening to give cause for us not to be so intrepid. Science many fields are like such, science has increased our health ,wealth and longevity, it has also produced weapons of mass destruction from TNT to nuclear arms, but science is never evil, it only seeks answers explanations, WE KNOW IT WORKS. Invented gods and the religions attached to them have no happy endings no matter what they promise, and do so playing on our fears, not our hopes, especially when they are devoid of any evidence. Religions by their very nature are designed to cause division, to offer an easy way out, it's not something to teach our children, that life is destined and by divine order, to feed their minds that it is wise to submit. Personally I think that is the epitome of evil. Truth does not stand alone, it is our quest to find it, and define it, nothing should be sacred, gods and religions are our worst enemies, not our friends.
@@derekardito2032 the universe (big bang) was the effect not the cause, so what caused it? Materialism cannot provide an answer, and the values associated with our universe have almost zero probability of coming by chance. And just on another note, not everything can be proved by science.
Fascinating. There is something about the fact that the more we look, as pattern seeking animals, the more we find. On the one hand, in the unimaginable vastness of the universe (universes), we are so tiny as to be negligible and on the other hand without us to observe things they almost have no significance.
There's strength in numbers. Lots of observers mean lots of waveform collapses.
If a mouse farts in a forest... but no-one is there to hear it - has it really farted at all? 😉
Small correction: “Infinite number of universes” is wrong. Infinity is not a number, it’s a concept. Any number, no matter how big it is, is puny compared to infinity.
So how else would you say there's an infinite number of them?
