Teacher: "Why didn't you do your homework?" Me: BECAUSE EINSTEIN SAID SO
Can't argue with that😂😂😂
Teacher:hes dead DETENTION
Teacher. "Why didn't you do your homework?" Me: "I didn't go home so therefore I had no homework"
BinaryInf big brain
"The homework was too hard, so I spent the night trying to figure out how to go at the speed of light so time would stop, and then the homework would never be due."
What I always found fascinating was the time dilation. When a light particle is created from our vantage it can take thousands of years to escape the sun. Then about 8 and a half minutes to get to the earth and the back of your eye where it annihilates. But from the particles point of view due to time dilation it would be instantaneous. Thus creating and annihilating at the same time. Drawing out a null line. A distance crossed in zero time. This one little thing in relativity melted my brain.
That is because the only real constant in the universe is the one thing that we still do not truly understand. gravity. Time, and therefore, the speed of light is only truly relative to gravity.
One thing that always fascinated me about this concept is that, from the photon's point of view, it only exists for a timeless instant as a line connecting its creation point and its endpoint. This means that the endpoint of the light beam effectively exists as a beam that crosses time as well as space, since the endpoint is in the future of the creation point. It's mind-bending to wrap your head around.
It's all hypothetical, so, he is my interpretation. If light has life, it's processes would be effected environmentally. Thusly, to me, light would be capable of thinking and processing that information as fast as say, itself. So, upon that thought, it would be be 'being, living, etcetc' as we do. So around it (this living light) it would see everything frozen in time around it.....🐻 Really hoping for someone to carry this thought forward or backward for me. My brain hurts after fiction/factional thinking's🐻
Another way to think about it is space dilation, the photon leaves and arrives simultaneously experiencing no time as well as traveling through no space. The space between becomes shorter and shorter as you approach C. A photons departure point is the same as its arrival point from the photons point of view
@@slo3337 Indeed, no time, no distance - from the point of view of photon it never existed! :)
That's the best lesson on light speed I've ever seen! It's the first time I've felt like maybe I kinda sorta understand it! So, I've gone from being totally whacked out confused by it to now kinda sorta understanding it... a giant leap! Thanks so much!

If you could send a message faster than light, and the receiver of the message was moving, then time dilation could be bigger than the time the message spent in transit. So it would be possible to receive a reply before you even sent the message. This is known as Tolman's Paradox, and it's why most physicists are highly skeptical about any kind of FTL hacks, including wormholes.
Time dilation is somewhat of a fairytale think about it we made up time to more effectively manage our days even simple things like second minutes days years moths are made up to fit the planet we live on time is something the universe doesnt care about add all
Wouldn't that mean that we just need mass to energy converters? Then we could "beam" to precise locations anything and reassemble it exactly as it was nearly instantly.

Majesty:: Mercury can. !!! Majesty:: if we can measure light speed in A one meters above. And we can measure the the light mercury content in this one meter light.

So to negate Tolman's paradox would require the FTL message to 'deflect' the right amount into the future of a time dilating receiver to resolve the paradox. Interesting possible new 'field' effect-- the Tolman anti-dilation Field if you like?

Steven Hawking, Micio Kaku and many other snobby scam artists pretending to be theoretical physicists, just played it safe when they chose to be experts on intellectual esoterism, that is not going to be testable, that have no predictions that could be derived from the unprovable "teories". So they can pretend to know something by imagining an elaborate intellectual construct they call teory. Even tho almost no one claims to understand it. And since they can't prove it, no one can disprove it. Handy.
i mean... the simple solution is just change the speed of light :P or instead of you needing to move you could just have something else move you which could also allow it (warp, Slipspace, Hyperspace, wormhole) :P

This seems familiar
I discovered sound had a finite speed when I was 6 years old. I remember watching some dump trucks at a construction site dumping rock. I was about 1/4 of a mile away. I noticed after the truck dumped it load and started lowering the truck bed the rear door would slam against the back of the truck and it took a second for me to hear the bang created by it. I was fascinated by it and sat there for a while to keep hearing it.
I saw a man hammering a fence post into the ground at the other side of a field. Over and over again, the sound of him hitting the post reached me at the same time as the sight of his hammer reaching the top of his next swing. It looked weird.
Massive cool,😁👍
It rained, and the sound of lightning came seconds after I saw the flash. Significantly more boring revelation I must say :')
@@sweginator1084 Knowing the speed of sound at ground level, by counting the seconds between lightning and thunder we can tell how far away the storm is.

7:51 the image that had haunted my mind was not needed. I was listening to the video in the background rather than actually watching so I wasn'texpectingit in the least. This was otherwise one of the best video I've listened to so far perfectly explaining such things I wouldn't have been able to comprehend if i was simply sitting in a classroom being told something I'd already heard millions of times before taught in school.
So you would rather waste 18mins of your life by some guy with a fake mustache then listen to the real explanation that he never even gave? Strange how you even came to an understanding when he didnt even offer one. The truth is that you have to be light to travel at the speed of light, and the only things that can faster dont exist so technically nothing can go faster than the speed of light and exist at the same time. Not sure what classes fucked that up for you a million times, but this man is NOT the solution.

Since the speed of light, hence the propagation speed of fields, must remain constant for all the other fundamental constants to continue to be proportionally the same, mass (process) has to increase in order to keep up, but to a limit. Once we go over the speed limit and fields can no longer keep up, matter disintegrates. When we reach the speed of light, wavelength and frequency drop to zero, waves become flat, devoid of any information, and we are back to being immaterial empty space.
its not even the thing ur talking which they are very good well put in but its the images and video quality its jaw dropping bro. just amazing hard work
The only reason we can't travel faster than light is we can't make an elastic band strong enough
That elastic band will have to be at least the length of the Milky Way

The speed of light as a constant is the biggest scientific misunderstanding of all time and the one person to blame is Albert Einstein. That one error although small in no way discredits him as it is now over 100 years ago that the error was mad, and he surely can be forgiven for that. The error was specifically in the famous equation E=MC^2 and must now read corrected as E=MV^2 (As C is a variable not a constant). This revised equation is now compatible with the equation for Kinetic energy, EK = ½ MV^2. It is a very small alteration but mind blowing in its implications It explains why the edge of our Universe seems to have an expansion rate that exceeds the speed of light. It explains why the GP satellites (all 80) have a universal increase in their timing circuits It also explains why we are experiencing Gravity waves where there is nothing anywhere near to explain them. It give a new insight to gravity lensing. And explains why time slows down near a black hole. Need I go on. Obviously this is only a short look at the problems all of which I have explained in greater depth in the past. I am not asking you to believe me but to look at the proof that is staring us all in the face. The Ultimate answer is that Gravity controls time . A very simple statement but very great in its effects. Each time I hear that scientists are scratching their heads over some Cosmological conundrum I can usually pin point its cause to Gravity controlling time . I have fuller transcripts for the cause and effect of all of the aforementioned items many of them published on ’LINKEDIN’ at one time or another. Regards to all. MoK
math says if +1= speed of light, and 0 = stationary, you need to -1 to get back to stationary. which creates additional problems to solve. #1 1 block of energy = 1 speed of light. this means that 2 blocks of energy are needed. one to accelerate, one to decelerate. 1 block must be able to do everything, accelerate/decelerate to and from plus payload. The problem is the amount of energy block needed for this mission, not speed of light. Also, if we are using that energy to travel to another star system, why use that energy harvest what inside of our star system. #2 Space is full of "particles" that are sized from obviously to barely visible. Hitting one of those particles at or faster than the speed of light = mission failed, game over and try again. Light is slow relative to the universal scale. if we were to map the way to "new earth" using light as our main from of observation, we would need to be able to correct the path faster than we would be able to make the observations. the solution this is knowing where everything is and where they are going to be in the future. . . . why do we need to travel faster than light again? knowing where everything is and where they are going to be in the future seems to be the best practical answer.

Sound has an echo of vibrations that create the sound like for instance playing on a guitar. Soumd does not exist in space or the universe but it does have echoes of vibrations heard by specific radio frequency computer's etc. There is one thing that could create speed that travels faster than light i think the key to this is using vibrational frequencies and turning those frequencies into energy that creates diffrent speeds of frequencies. By creating a certain machine that converts frequency into energy particles that would be released by the engines of a spaceship to create velocity greated than the no weight of the spaceship. Maybe create a solar panel that can absord vibrations of frequencies.

@@TheSchnieder6 Kid named No One:
The key to everything is vibration. Everything started in a singularity with a diffusion of matter not explosion. No big bang ... Look at the CMG and how even it is. Is that the look of an explosion? If you say it is, point to the center of the explosion. Matter and Entergy are the same. Dimension/Time is formed by matter vibration. Without vibration you have no dimension. Ok Now the reason heat is even across the CMG is because of heat/Quark etc at a vibration can return to the singularity. Which is everywhere in it`s singularity. It`s one dimension. Only to return if it`s vibration pushes it back into 3D. You can see this as quarks disappear and reappear.

@@MrAaronvee I see you have nothing but insults. How about go bugger off.
What i always wondered about in experiments like the one with the clocks in planes (and in case my school teacher tought us that: Apologies, that i forgot that): How do the clocks in the plane know, that their time has to pass more slowly, because they were the ones beeing accelerated and slowed down? Why weren't the clocks on the ground beeing accelerated and slowed down in the opposite direction? Shouldn't they all be in equally valid inertial frames of reference? Or in other words, if the clocks in the planes from our (and clocks' on the ground) perspective have slowed down, why haven't the clocks on the ground haven't slowed down from the pilots (and clocks on the plane) perspective? How do we exclude the possibility that there was no side effect ruining that experiment, like for example, beeing exposed to more vibrations, or beeing futher away from a big mass like the earth, or whatever?
I've heard that, to measure the speed of light, you can't have something at the other end sending a message when light is detected, because that message also travels at the speed of light. This means that you actually measure how fast light travels from point A to point B, then back to point A, and you have to divide by two and assume that there are no changes in speed. It is possible that light travels instantly from point A to point B, then takes the rest of the time from point B to point A, and we wouldn't be able to know that. I can't remember where I read that, so if I'm wrong, don't hesitate to correct me.
Yes. You saw it on a Veritasium's video possibly. But that is not really a scientifical answer. Like someone answered in the video, the reason we know that speed of light is constant in all directions is not because we measured it, but because we can obtain a wave equation from Maxwell equations that describes electromagnetic waves (light) with a constant speed. This constant speed is a function of other constants, we have the speed of light as a function, we dont necessarily need to verify with an experiment and achieve anything.
@@KostasTsakalidis Thanks for the precision. I think you're right, it must have been from Veritasium. Ngl, this is a bit too advanced for me, so even with your explanation, I struggle to understand the principle, but that's alright.
Indeed, this sounds just like something one would parrot after misunderstanding veritasium... Now to misunderstand the banarch tarski paradox. XD
@@KostasTsakalidis "we dont necessarily need to verify with an experiment and achieve anything" more heretical words have never been said. Experiment is everything.
@@snakeoo7ca We don't know if anything exists. Let's take your example with gravity: We don't have quantum theory for gravity. There are some indications that it might not be a quantum field at all, and that it might be an emergent property. Understanding the nature of the gravity, including whether it actually exists or is it just an illusion created by more fundamental interactions, is at the forefront of physics and must be tested with experiments, just like anything else. We need as many experiments as we can, and we should constantly try to invent new ones, to increase our confidence level in how things actually work. Scholars forgetting that the ultimate judge is an experiment and getting lost in logic/math is a trend that has been going since before physics existed, and has prevented many great minds from realizing their potential. Going back to the one-way speed of light, here have been many attempts at constructing an experiment for measuring it. This alone proves that it's a problem people take seriously, rightfully so I must say.

I like how you make more tangible concepts that are difficult to grasp.. I have a challenge for you. Try to explain why FTL travelling, breaks causality. I explored the topic more than you can imagine but my head still can't wrap around the idea. The best explanations I have seen involve plotting a time x space chart. Which helps little on picturing the reason if I hop into a wormhole to the center of the galaxy then come back I will arrive before I have left.
'light' emits pressure and the escape velocity from which light emits from atomic structure is constant. Just as wavelengths are simply convenient descriptions of light it doesn't make them as described because they are obviously a form of fluid. light is heavy and it hurts as well as gives us clues to our surroundings, our atmosphere is very heavy and thick just as this light is. 'Time dilation' is simply a product of gravitational force on how we observe time keeping systems. Unless you can tell time without existing it's obviously going to be different based on distances from large gravitational bodies. The sun, the moon, the Earth are all affecting how time keeping systems tick as well as any form of constant acceleration is going to act on these atomic systems and cause perturbation in electron orbits affecting time keeping. Acceleration naturally elongates orbits of orbiting bodies or electrons... this is very well known, but isn't readily observable because the method of action that is acceleration of a body with orbiting bodies is artificial and not practical to even conduct an experiment, but you can easily demonstrate with magnetism. You accelerate a body with magnetic orbits time of orbit will slow down... no time did not slow down. Just because these things are calculable with convenient expressions doesn't give credence to the expressions being representative of reality. Humans agreeing on things has no bearing on legitimacy of this school of thought even if the communication results in furthering scientific discovery or even if it can predict phenomena undiscovered. In fact, this agreeableness is hampering other schools of thought from developing. However you can use current agreement to further explain concepts that are more accurate. Energy = the configuration of mass * energy available to reconfigure mass squared. This allows for a space engine to gain speed without propellant simply by spinning itself and using timing mechanism to accelerate itself in a single direction. The method of releasing requires no energy and spinning an object is not relativistic to any other body in existence. So this theory agrees with relativity and can continue to surpass the speed of light just as close orbiting bodies of black holes already surpass the speed of light so can you also eventually get a large body to gain enough speed to surpass the speed at which emission of light from an atomic system happens.

The speed of light is the fastest we can go through space and time but with something like a warp drive which has had study on maybe theoreticaly being possible. This means we would be moving outside of spacetime
Einstein never predicted the existence of wormholes, he just stated that - mathematically - it's not impossible. That's a very different thing. For wormholes to exist, you need something that has never been discovered yet, and is unlikely to exist (at least in great numbers and / or nearby): anti - gravity. Without that, wormholes will never be more than "not impossible". For the rest a very informative and good video!
I'd love to see anti-gravity and wormholes in an accurate computer simulation based on the classic model. Would be very interesting.
It might be that we can't perceive the phenomenon without special equipment
Anything travelling back through time would in our time flow repel objects as their gravity would be inverted, like Tenet.
No anti-gravity. Negative energy. The same with the Alcubierre Drive.

@Giovanni Roman “yet”: great attitude. I love it.
@Giovanni Roman i suggest you watch videos that are factual and not by random individuals who may not even understand what they are on about
The other method of FTL travel outside of wormholes that can bypass relativity is spatial expansion... Space expansions can happen FTL (we can measure galaxies moving away from us faster than the speed of light, because they're not actually moving, space is being "created" between their galaxy and ours making them redshift ftl), this in theory means you can create an warp bubble using exotic matter to contract and expand space around a vessel moving it FTL without technically moving it (basically warp drive in star trek).... physics is fun
Sound doesn't have a finite speed. Simply put the perception of sound (and by that I mean the entities that can perceive sound) is limited by the conditions that exist when the entity is present to perceive sound. All the different atmospheric conditions that exist on the planet alter the perception of sound. Air pressure, air density, humidity, even reflective walls all to your perception of sound. Now on to light. It is impossible for us as physical beings to measure any possible speed of light. For one particular reason. We can only use physical instruments to measure light. And the physical instruments are limited by the conditions and restraints put on them by the environment. Again, to put it simply, any combination of instruments that you set up to measure the speed of light always has a logical flaw in it. Speed is a measurement of the distance and object or particle travels in a given amount of time. If you were to set up an instrument to measure the speed of light, you're troubled by the concept of moving the instrument from point A to point b. You are troubled by the concept of conditions that are out of control in the environment, similar to the conditions of weather on sound, gravitational forces alter the speed of light. This is been proven multiple times, and is now an accepted fact. To clocks that work exactly the same on Earth, put one in orbit, the time they're different. Just a small variation and gravitational forces alter the speed of light. and considering that all gravitational forces are always changing, depending on the conditions in which you measure speed of light, the infinite number of variables are incapable. By the way, shave the mustache grow your hair back lose the suspenders. You look like a chimney sweep from 1890.

Even tho it isnt possible. Its a fun thought breaking question for when u get bored In thoery, discarding a buncha physics stuff. If u went faster then light, turned around at soke point and looked behind u. U could see the "light" from u previously coming towards u. In theory urself in the "past" but ud never get remotely a clear image from it. Ud prolly just be a glowing ball from the ammnt of energy being put off in the process I guess nothing happens then. 🤷 theres no way to possibly try to measure something like that. With current physics anyway. Same for future physics i guess. But still fun to think about Theoretically if u go far enough out in space fast enough, discarding the impossibility. U could turn around and see the past. So, time travel but only visually. Like how the light from the sun we see actually was put off a little while ago "i forgot how ling
Light is limited to the maximum rate of induction of a transverse eletro-magnetic wave in the aether. However, dielectric waves (rarefactions) are faster. Pie/2 faster. Saying that the mass increases as you get closer to speed of light is non sensical. Because that means the quantity of matter increases. It is more accurate to say that the inertia increases. Wormholes will only be possible through counter-space. But this will not be due to warping of space-time.

Measuring the speed of light in MPH - BLASPHEMY!
Totally agree. mph is practically as bad as measuring in cubits when it comes to establishing wavelengths in free space. velocity 300,000,000 mps (approx) in free space / frequency in Hz = wavelength in metres.
And he got it completely wrong. The speed of c in MPH is 11,160,000. He was nowhere near! EDIT: Sorry guys, my math is off. I did 186,000 miles per second x60. This actually gives you the speed per minutes! Turns out he is right and I'm a dumbass who obviously hasn't had enough sleep
In stead of making a new comment... “MPH??? Seriously????????????” We are 5.9 quadrillion inches from the sun? That is a lot of thumbs!

By bending space directly in front of a space craft, the "ship" would theoretically "fall" into the bend, which would also theoretically warp time. as this happens repeatedly while the ship continually warps space directly in front of it, it would seemingly arrive at its destination, no matter how far, in an instant. And no doubt with technology able to do such a thing a civilization would most likely be able to manipulate space in such a way as to create a force field which would create a dampening effect on gravity and thus the occupants would not be affected by any inertial affect. This spacecraft technically would not travel at the speed of light however space along its route in front of it is what moves the entire time. Traveling at the speed of light or seemingly so is possible if you think outside the box
Matter is made of mass, electric and magnetic charge. Initially all input energy goes into accelarating the mass. As speed increases lesser energy is available for acceleration since more energy starts flowing into EM fields. To maintain constant acceleration more energy is needed. At light speed all input energy is transferred to EM field and no energy is available for accelerating the mass and velocity becomes constant.
I swear. The day wormholes are discovered is when you'll see Tesla and Einstein on the other side sipping mai tais in Cancun shouting, "WHAT TOOK YOU SO LONG?!"

Ever hear brain puzzle about the "light speed laser lighthouse"?? Its bugged me for two decades - having heard it on CBCradio 🇨🇦 The idea is - what happens to the laser light shot from a rotating super powered lighthouse in space - fast spin pulsar kinda thing sorta i guess what do i know me just artist ah So this light speed beam would then rotate closest to speed of light asap Q: Should the beam twist at some extreme distance Or whip the beam faster then the speed of light ! Hope that hurts your genius brian (sis) too!
One way that I've heard it explained is that things might be able to exceed c, however, at that point we cannot perceive it and the principle of cause-and-effect breaks down. So effectively it would have to depart the universe as we understand it. I don't know if that means it is just unknowable or if it actually enters another dimension/universe.

Shut up
In reality approaching the speed of light mass does not increase, density increases due to gravitational friction. Gravity increases around an accelerating mass, increasing its density causing resistance to acceleration. Mass only increases by the introduction of more mass or an increase in the variable motion of the amount of energy of a mass. Yes, it only appears to gain mass. But it actually increases in density. Time is abstract. Time is the measurement of motion. Time dilation is truly gravitational dilation where the motion of things are distorted. Time is merely used to measure the distorted motion. Actually, wormholes would allow one to move incredibly faster than light. Within them travel would be along with it carried along by quantum gravity, unlike traveling against gravity within 4D space.
8:06 It's not 0.0006% the speed of light It's 0.0006 *times* the speed of light, which is 0.06% the speed of light If you try to edit the article about the Parker Solar Probe on wikipedia, you will see an added note saying: "Do NOT "correct" this figure. 0.064% IS CORRECT. Notice the percent sign; 0.00064 EQUALS 0.064%. If this is not clear, please see the discussions on the Talk Page."

0:58 actually from lights point of view, with time dilation taken into account, it is instantaneous. It only has a velocity according to an outside observer. Because, according to the photon itself, it took 0 seconds to go from it's start point to interacting with a piece of matter. Without a time reference, velocity cannot be calculated. So technically if you were to travel 1c, the travel time would be instant, but to someone else, your travel time would be however long light takes to travel that same distance. Also, because of the reference frame, you would be unable to calculate your own velocity.
big brain
yea tbh this video was not very comprehensive or detailed it was a pretty basic overview but still a g vid
This is very true
Well instantaniouse would mean in this case that light would reach its destination instantanious. Therefore meaning that it cant have a speed, or source. because if it has a source there must be travel distance, and therfore there must be a constant speed, this speed might not be observable to you or me, but if you take the lights point of view there would actually be a travel time, givem theres enough distance. But if you mean it would reach light speed instantanious, you are right for light can not go faster or slower than light speed, therefore if these photons pop into existance time dialation would give the photon the time to get to light speed instantly. I hope you understand this. I hope i understand myself
@@Alexander27463 see, there's where scientists have trouble when it comes to light. Light does travel a distance but does so without time being a factor. (Relative to it's own state of reference) time dilation doesn't affect us while the light is traveling, therefore giving light a velocity. If you were able to put a saddle on a single photon and ride it from start to finish, (the point where you start measuring to the point you stop measuring) then from your perspective, the trip took 0 time. Although people watching you go by would see you traveling at the speed of light. It's also why the answer to the question "if you were in a car going light speed, what would happen if you turned on the headlights?" That light would still appear to travel away from you at the speed of light even though you are traveling that speed as well. Another good example of this (what I stated previous comment) is the Minkowski Diagram.
2 fictional ways to travel faster than the speed of light is: 1. Have usable and renewable energy usage on a vehicle capable of moving faster than the speed of light. An example would be a mini sun on a spaceship or maybe a warp core. 2. Bringing point a and point b, closer together. Ways such as warp drives, wormholes, portals, phantom drives, spore drives etc.

Why do I feel like Einstein is a time traveler. He's predicted everything.
yeah maby. time travel is not impossible. only traveling back in time is theoreticaly unachiveable but not imposible. as in going back in time is theoreticaly somthing real but just unachievable
there is no such as time traveler, but travelling through parallel times is possible coz the space is infinite. If he is, what actually happened is he left his modern old world and went to our world
He didn't predict anything. And he didn't believe in quantum mechanics.

Theoretically we could build an Alcubierre drive that would form a wave of space time behind the craft that would be able to propel the craft faster than the speed of light without breaking laws of physics because it moves the space around the craft instead of the craft itself. However this would require negative matter which has obviously not been discovered in nature or created in a lab.

Photons actually have a mass but not a resting mass i.e. if a photon would theoretically be resting it would have no mass. But otherwise due to the fact that the photon is travelling at c it has a certain energy which can be calculated into a certain mass (e(w)= m*c2). This can be proven too the more photons hit an object the heavier its gets.
I did not know photons were Catholic
But mass is defined as the resting energy, and so photons have no resting energy and therefore no mass. But perhaps this is just semantics. It is more useful describing them as massless though.
DANG JOS Mass is both rest mass and moving mass, but since we rarely ever use moving mass in basically anything, rest mass is being shorten into simply mass
@@rsfakqj10rsf-33 But if you define it that way, the mass will start to have a pointless meaning. You might as well call it the total energy. What would be the difference? And would a particle in inertial motion warp spacetime more than a particle at rest? If not, then that's another limitation to calling it mass.
DANG JOS mass is the total energy of a body, we get mass because the energy in our body interact with the fields, we are made of atoms and energy; atoms are made of protons, neutrons, electrons and energy; these things are made of quarks, bosons, leptons and energy, these things are theoretically made of strings or vibration in the energy field or basically energy
The speed of light sets the scales. For fields to continue to work regardless of spacetime conditions, there must be time and spatial distortions between the observer and the observed when moving at relativistic speeds. This is where the principles of relativity and equivalency come from. Because a field's speed must not change regardless of relative motion, and because energy is finite, for reality to work, all parameters must be adjusted around the speed of light. This is how and why we get time dilation and length contraction.
I'm really surprised he didn't cover length contraction in the video, considering it would eliminate the need to travel faster than the speed of light since the closer you get to the speed of light the more your surroundings shrink which would allow you to move anywhere in the universe almost instantaneously. Of course he did rightly point out your mass would approach infinity and it would take almost infinite energy to achieve. But theoretically it's possible.
I suspect there are many different speeds to go with the many different types of light. I also suspect the speed of all forms of light can be accelerated under the right conditions. Light is caused by a frequency of sorts created at the molecular level. It's the frequency we need to accelerate, not the light itself. The light is just a biproduct. If we accelerate the frequency, we should also see an increase in the speed of the biproduct.
i discovered your channel today and i higly appreciate the fact, that you are talking clean,calm and slow enough to follow. I am german and apart from the fact, that this video is really well made i was able to understand it. This is something rare these days so thank you for that.
Actually, mass doesn't change with velocity - rather, momentum, p, in special relativity, has a non-proportional dependence on velocity. The fallacy that mass depends on velocity, as m = γm₀ , where γ = 1/√(1-[v/c]²) arises from the false assignment of the "γ" factor in the momentum formula p = γm₀v to "m," when in fact, it belongs with "v;" that is, it governs the way momentum (not mass) depends on velocity. It is also refuted by the different way kinetic energy, T, depends on velocity: T = (γ-1)m₀c² ≠ ½γm₀v² It is these velocity dependences that mathematically limit |v| < c for any object with mass.

There's quite a good argument that states that mass changes with electrical charge.
@@mikeharrington878 Electrical charge can't change without the transfer of charged particles, which always carry mass. So how can electrical charge change be separated from mass change? Fred
that is why if a mass ever did make it to light speed it would be converted to energy?
The practical speed limits are far less than the physical limit, being the enormous energy requirement to bring any habitable spacecraft to anywhere near the speed of light and the elephant in the room, micrometeoroids and other uncharted space debris.

Light dances through Space-time and (because of time dilation) light is bound by only by gravity. The omnipresence of gravity dances across the infinity of space-time, Gravity can bend light and it can bend time. We forgot how to manipulate gravity a few thousand years ago. I suspect it was combining sound and light frequencies to temporarily suspend mass, but I am guessing. Levitation is possible we just don't remember how we did it. The secrets of the universe are suspended in gravity.
The video conflates 2 different questions. 1. Why is the speed of light 186,282 mps and 2. How do we know that the speed of light is 186282 mps. Question 2 is easy to answer (A) We have measured it and (B) according to Relativity time slows down the faster you go. However, the first question goes unanswered. Why does time freeze at 186,282mps and not say 186.281 mps.

New insights after 3 years! Not that I'm an expert (shamelessly stolen from others on the internet) but 80% of "mass" is created by particles moving through the condensed Higgs-Boson field. Which means that the "divide by zero"-singularity in Einsteins equasion is probably not a zero. Sabine Hosenfelder has gat a nice video about this. Hence, the speed of light is more a barrier of some kind, which, after crossing it, the laws of physics will restore again.
One problem. We know there are galaxies we will never be able to see because they are receding from us faster than light. Which means space warps are an exception and causality is only affected if you can return to your point of origin before you departed. Relativity is already violated which means that the theory doesn't account for direct manipulation of space time. There is no catastrophic result from an observer seeing you pop into existence, than watching your ghost photons recede into the distance. Assuming that they aren't incinerated because light years of photons were stored up at the front of the warp and arrive before you after all in the form of a gamma ray burst. Relativity already is a broken theory because Einstein didn't know the Universe is expanding faster than light. Expanding and infilling with fresh new space.
