I seek refuge with God from expelled satan Holy Qur'an Chapter 67 - The Dominion 16. Have ye taken security from Him Who is in the heaven that He will not cause the earth to swallow you when lo! it is convulsed? 17. Or have ye taken security from Him Who is in the heaven that He will not let loose on you a hurricane which flings rocks? But ye shall know the manner of My warning. 18. And verily those before them denied, then (see) the manner of My wrath (with them)! Chapter 16 - The Honey Bee 45. Are they who plan ill deeds then secure that Allah will not cause the earth to swallow them, or that the doom will not come on them whence they know not? 46. Or that He will not seize them in their going to and fro that there be no escape for them? 47. Or that He will not seize them with a gradual wasting? Lo! thy Lord is indeed Full of Pity, Merciful! 48. Have they not observed all thing that Allah hath created, how their shadows incline to the right and to the left, making prostration unto Allah, and they are lowly? 49. And unto Allah maketh prostration whatsoever is in the heavens and whatsoever is in the earth of living creatures, and the angels (also), and they are not proud 50. They fear their Lord above them, and do what they are hidden. 51. Allah hath said: Choose not two gods. There is only One God. So of Me, Me only, be in awe. 52. Unto Him belongeth whatsoever is in the heavens and the earth, and religion is His for ever. Will ye then fear any other than Allah? 53. And whatever of comfort ye enjoy, it is from Allah. Then, when misfortune reacheth you, unto Him ye cry for help. 54. And afterward, when He hath rid you of the misfortune, behold! a set of you attribute partners to their Lord, 55. So as to deny that which We have given them. Then enjoy life (while ye may), for ye will come to know. 56. And they assign a portion of that which We have given them unto what they know not. By Allah! but ye will indeed be asked concerning (all) that ye used to invent. Chapter 7 - The Place Between Heaven and Hell 96. And if the people of the township had believed and kept from evil, surely We should have opened for them, blessings from the sky and from the earth. But (unto every messenger) they gave the lie, and so We seized them on account of what they used to earn. 97. Are the people of the townships then secure from the coming of Our wrath, upon them as a night raid while they sleep? 98. Or are the people of the townships then secure from the coming of Our wrath upon them in the daytime while they play? 99. Are they then secure from Allah's scheme? None deemeth himself secure from Allah's scheme save folk that perish. 100. Is it not an indication to those who inherit the land after its people (who thus reaped the consequence of evil doing) that, if We will, We can smite them for their sins and print upon their hearts so that they hear not? 101. Such were the townships. We relate some tidings of them unto thee (Muhammad). Their messengers verily came unto them with clear proofs (of Allah's Sovereignty), but they could not believe because they had before denied. Thus doth Allah print upon the hearts of disbelievers (that they hear not). 102. We found no (loyalty to any) covenant in most of them. Nay, most of them We found wrong doers Chapter 11- Prophet Hood 77. And when Our messengers (angels in man shape) came unto Lot, he was distressed and knew not how to protect them. He said: This is a distressful day. 78. And his people came unto him, running towards him and before then they used to commit abominations He said: O my people! Here are my daughters! They are purer for you (to marry). Beware of Allah, and degrade me not in (the person of) my guests. Is there not among you any upright man? 79. They said: Well thou knowest that we have no right to thy daughters, and well thou knowest what we want. 80. He said: Would that I had strength to resist you or had some strong support (among you)! 81. (The messengers) said: O Lot! Lo! we are messengers of thy Lord; they shall not reach thee. So travel with thy people in a part of the night, and let not one of you turn round (all) save thy wife. Lo! that which smiteth them will smite her (also). Lo! their tryst is (for) the morning. Is not the morning nigh? 82. So when Our commandment came to pass We overthrew (that township) and rained upon it stones of clay, one after another, 83. Marked with fire in the providence of thy Lord (for the destruction of the wicked). And they are never far from the wrong-doers.

The idea of a kilometres-wide chunk of iron getting so hot that it becomes - not just a liquid, but a GAS - is genuinely hard for me to imagine.

Yeah, falling at 60,000 kmph!
That's when you realize that the "velocity SQUARED" component of kinetic energy starts to get seriously ridiculous at very high speeds. And the law of conservation of energy states that if you are slowing down, that energy has to go SOMEWHERE. And if you slow down all of a sudden, well you get the energy all of a sudden too :)
Yeah that was pretty crazy to think about
and when it hits, its back end will still be several kilometers in the sky.

He also discovered the Kuiper Belt! Not only is he a badass, he's a damn legend.
The DART experiment has shown that we do have the ability to deflect a asteroid with a high velocity impact. I know that happened after this video was made. It was an important experiment and a fun one to see live.
Did they ever give us real factual information about the impact and how much it would move?
They changed the orbital periodnof the 2 bodies in relation to each other. Did they ever release any data on any changes in relation to Earth? Doesn't matter what happens if it's still heading to Earth.
But. DART works if we know in advance we are going to be hit. The meteor that hit Russia we did not see coming..You cannot redirect of you do not see it coming..
For anyone coming here after the DART mission: Page 73 of the linked report on Planetary Defence (detection and mitigation) says that Kinetic Methods are feasible. Since David Jewitt was on the steering committee for that report, I'm pretty sure he knew this. It's interesting that the video only shows non-kinetic methods and why they are unlikely to work. Bit misleading, that.

@@nicolausteslaus lol, true tho
Make it a double DART. Asteroids travel in pairs, one being a decoy to distract us.
About the foil and its reflective properties; wouldn't it be much more efficient to paint the object with a hyperreflective pigment/color? This doesn't solve how to get there with all the needed equipment, but I think it could work if someone figured that (very important) part out. A number of drones carrying paint could cover a large area in no time.

I love how much you rescued this video's performance in the algorithm with a thumbnail flip.
I start to think that evacuating a city can be done quickest if you let the people walk. You close all roads exept for transport of those who can't walk. In a week's time, you could reach another big city walking. If people flee in all directions, the masses thin out. So, if you have many evacuation centers all around the city in a distance of a five days walk, you can transport the people from there.
Thats what I was thinking… If the roads are blocked then any reasonable person would simply start walking. A few days is more than enough time to make it out of a city on foot

think about that more carefully
It's scary that we still aren't that good at detecting asteroids, but the size of the universe and all the objects within space makes it so hard to predict. The idea of wrapping tin foil around an asteroid seems like something out of a science fiction comedy movie, but it's cool that the radiative properties of some metals are something to think about when entering outer space.
The fact that we don't have a rocket that could deflect an asteroid, but plain old photons could, is quite funny to think about.
I also find it weird that Space X haven’t mentioned this with their ‘Occupy Mars’ goal. If it’s difficult for us to detect from Earth, surely Mars is even more difficult? Imagine investing all that money only for your colony to be wiped out by an asteroid before it gets fully going.
I didn't get how the foil thing (unrealistic as it is to begin with) would do anything to a spinning asteroid of fairly uniform composition. Maybe it's spinning VERY slowly (days) and then we'd have to only wrap (the correct) half of it? Lmao ok. I'm ok with asteroid catastrophe anyway tbh.
@@Vote_By_Mail it'd be constantly pushed away from the sun by photons from the sun. doesn't matter if you have to wrap the whole thing, sunlight is still only coming from one side

Actually, cities occupy a tiny percentage of the Earth's surface and are unlikely to get hit directly. However, 71% of the Earth's surface is oceans, and a water impact could result in a megatsunami that would wipe out entire coastal cities even thousands of miles away.
You're already dealing with a 1-in-a-100million+ event; your other "tiny percentage" things start goin out the window.
Not only one Tsunami, but multiple. If an asteroid impact the ocean, it will create a "Hole" where there is no water, which is the first tsunami, then water will rush in to fill the hole, causing a bulge in the center so high that when it falls back down, it will create another tsunami, this, however won't create a hole, but it will create a depression in water lever where water will rush back in, causing another bulge, less high every time. So we can count on at least 3-5 tsunamis in a row, with olny a few hours in between. Each tsunami will be less high and powerfull than it's predecessor, but even the last one will make the one that hit japan and the one that hit indonesia a couple of years back look like ripples.

A mass driver! That's somrthing that we've been theorizing about for a while.
Have a look at the Younger Dryas impacts circa 12,450BP and again at 11,600BP.

Thank you for answering a question I had. I wondered where the few but very large concentrations of certain metals came from, such as the huge gold and the nearby huge platinum chunks located in South Africa. Now I know they came from the cores of planets that broke up to form asteroids before crashing into Earth. Seeing more of the video, I saw him mention how the asteroid gets obliterated. However, it still answers my question because the gold and platinum chunks are not pure gold or pure platinum. They are just high concentrations of gold and platinum.
Would be great if you could make a second part to this video. Here we are, 2 years later, and there is the NASA's DART mission and the news: Oct. 20, 2022 - The DART spacecraft successfully impacted the asteroid Dimorphos on September 26, reducing the period of the asteroid's orbit by 32 minutes. Scientists considered a change of 73 seconds to be the minimum amount for success. This article has been updated to reflect the latest data and images from the impact. - and compare this success to the ideas in this video (nuke, rocket, kitchenfoil, evac)
love it when the caveman solution works perfectly

14:40 - what about setting up space mirrors (like the JWST) to reflect the light of the sun and focus it on the single point of the asteroid? We need to get to work on it right away, because we're gonna need a lot of mirrors and a hell of an efficient targeting system.

Never have I ever imagined that I would grow emotional for the dinosaurs that no longer exist...until I watched this. Watching the excerpts of cgi dinos trying to run from that unexpected pain really just sort of broke my heart. How horrible it would have been to just be minding your business, eating a plant or carcass...and BOOM! You're suddenly in excruciating pain and being cooked alive. How awful!
Most dinos died because of the aftermath of the impact. Dusts covers the sky for a long long time, barely any sunlight, temperature drops, plants can't do photosynthesis then die. It's like a slow torture to death. So... in a way, the ones that died due to being near the impact site is actually lucky.
Like the other guy said. The ones who died right away were sort of the lucky ones. They weren't really cooked alive in the way you're thinking. They died within seconds maybe even (milliseconds or micros seconds) of getting hit by the blast
Agreed!
Imagine what all the wild animals go trough every day.. being eaten alive, or starving to death
@@smilloww2095 that’s not nearly as worse as suffocating and burning to death? Tf you on

I just love how he says he wants to set your mind at easy by telling that you don't have to worry about asteroids ending humanity, there are other things that are more likely to end it before an asteroid! Like how is that comforting?
So Dr Jewitt doesn't mention the DART-style defense. DART launches in 2019, in 2022 impacts Dimorphos, a 160meter (20% of the 1km asteroid Jewitt is discussing) asteroid, 10.6 million KM away changing its orbital period by 32 minutes. Sounds like a decent defense to me, assuming we had enough warning time. Surly sending 10 of these DART-like missions millions of miles out would nudge it enough. Now maybe we would never have that sort of warning, but something about this should have been mentioned.
the main problem is that the number of darts required increases exponentially with the radius of the roid
@@asparagusoffice it grows as r^2 and there is a ceiling to the size of asteroids (most of the biggest are around 1km), even for 1km (some of the biggest objects), 120km away traveling at 25km/s, with our max payload launch objects 141,000km (dart was only 610kg--half of a car!) if we could hit it at 60km/s (instead of darts 6km/s) It would take about 1256 collisions to move it the 6000km necessary to miss the earth (again for some of the BIGGEST out there). BUT if the collision is a glancing blow we may need half that much. MOST IMPORTANT POINT: the calculations above assume a straight shot (which is almost never the case; this would give us 20 days to get it done--impossible), but usually we have FAR more time because most collide not via straight shots, but via orbits which can be calculated years to decades in advance--this would decrease the number of collisions needed DRAMATICALLY (for every additional 120mil km we need half the number of collisions) So even for 1km size asteroid it theoretically could only take 12 dart-style mission if the collision is 120 BILLION km away AND we are are talking of an orbit that hits in > 5 years we may have 10s of QUADRILLIONS of km before collision (I'm ignoring tons of orbital dynamics which may make things easier). We could theoretically be talking about a SINGLE dart-mission (maybe with a bigger payload) if we know the collision happens within 10 years (not sure how far out they can track these) EVEN for the biggest, 1km objects out there. And as you say the mass grows as r^2, so one 0.2% the diameter requires 100X fewer collisions. This rough math shows the orders of magnitude works out. This should at least be discussed. Otherwise, why have a DART mission. Is NASA just throwing away money? Or do the experts disagree here? There's more to be said for sure.

❤❤❤a shock wave from any aircraft breaking the sound barrier at ground level has the same effect of a falling or shooting star inbound at ground level, the reason they do isn't because they're out but because there in, or near the Earth BELOW the Firmament, they served their purpose, burn out get ejected from the firmament and another takes over ❤❤❤
One way to possibly defeat them in the future is some kind of hypervelocity kinetic energy projectile, like a massively scaled up railgun. It would likely punch deep inside and could force the pieces far enough apart to prevent gravity from pulling them back together quickly enough, depending on the range it is shot at from.

Humans: *make nuclear bombs* Meteors: look what they need to mimic a fraction of our power
Aestroids are lethal as they hit the earth at very fast speed usually faster then sound otherwise there is nothing they are just big chunky rocks
The four main Univeral forces according to M-Theory(The most accepted mathematical algorithm that explains the existence of our universe)is gravity,electromagnetism,Large Nuclear forces,and small nuclear forces.Impact collision is not one of them.But it can powerful nonetheless,but our sun is considered a small nuclear force.Meaning the bombs we create are microscopic compared to what our universe can create.
@@secretunknown2782 yeah they're nothing special they're just big rocks the gravity on our earth makes them dangerous
@@secretunknown2782 same as nuclear bombs, they're just chunky pieces of materials until they detonate....
