This guy is the teacher we all deserved.
Fr I love his videos I learn something new everyday
True bro......
I never would've realized how cool space was until I started getting hit with his facts.
Zack d films is enough for me 😊😊😊
But in our school days we had a guy who is always angry no wonder why his wife doesn't wanna sleep with him 😂😂
I love the t-shirt, "everybody dies" 😂
Its a saying in many cultures… no one lives forever, thats the truth of humanity. In Turkish we say "herkesin sonu kara toprak" which means "everyone’s end is black dirt". Or another one one "topraktan geldik topraga gidecegiz" which means "we came from dirt we go to dirt".
@@oguzhan9424humans didnt come from dirt
He is gon a make as die😭😩😢
Damn space junkies and their discarded needles 😂
The greatest video i could watch before sleep. Thanks what if I love the space videos!!
Me, every night 😂
I think the needle would be driven deep into the earth. I’d like to see the math on the needle’s mass - traveling at that speed.
You are correct. In my opinion, if a tiny needle used to sew the cloth can be made to travel at the speed of light and impact the earth, it will produce an explosion more or less the equivalent of 50-100 tons or 0.05 - 0.1 Kiloton of TNT. That is the equivalent of the energy released if the impact is strong enough to split every atom in the needle's material. He should not compute for the impact's kinetic energy model because the needle's material will not hold together upon impact but will instead vaporize instantly, and with it the dissipation of the kinetic energy. So in my opinion, that is the yield of the explosion and not as high as megatons or millions of tons of TNT like the large nuclear bomb that he said.
Infinite mass for any physical object reaching that speed.
@ That is just a theory. There's no such a thing as infinite mass. The mass doesn't change with velocity but the kinetic energy does. And no matter what the velocity of the object is, the computation formula does not change. Kinetic energy is directly proportional to the mass of the object (which is constant) and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. As you can see, the formula states that the mass remains at constant and does not increase with velocity. However, it's the kinetic energy (K.E.) that increases as the velocity increases.
There's a quora question about how much energy it takes to accelerate a gram of mass (about the mass of a needle) to 99% of the speed of light and it's something like 110kT of TNT, which is about ten times the Hiroshima bomb, so it seems like the video got it pretty close. The question is whether or not this needle would burn up in the atmosphere. Either way it has a ridiculous energy.
I can turn off the lights and be in bed before the light fades. Love my old coleman lantern.
If science was explained like this with the videos everybody would have straight As in middle school and high school😂
Yeah I'm kinda sad that I'm in my mid 40s and I really think we could engineer a working environment better than schools for kids to learn.. school only suits a small number of kids..
I absolutely LOVE this channel. He’s amazing, & I wish I had a teacher like him when I was in school🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥
What if the other laws of physics didn't work? Nothing with mass can hit the earth at the speed of light.
Light doesn't know it's fast. To light, a trip across the universe is INSTANTANEOUS 🤯
The explosion would be something like 44 trillion joules and equivalent to over 10 million tons of tnt, it would wipe out an entire city.
We went from needles to marshmellows to a whole a** cooked rotisserie chicken 🤣
Chuck Norris would thread it without slowing it down, that's what would happen.
The shirt is wrong we all know the cameraman never dies
Cap 😐😐
Every living thing dies, don't be stupid.
@ except the cameraman
Cameraman was the very 1st creation. Spawned into perpeptual existence.
Shout to the near infinite amount of virtual particle generations as the cameramen. As a constant collective of descendants they truly will never die out. They will live to see the next big bang,band the next one after too.
New fear unlocked falling debris from space and needles
Moving forward, any object that needs to survive extremes of: mass, speed, and energy should be made of "Unobtainium"
To the guy in the comments calling bs on the needle doing that kind of disaster: when an object impacts Earth, it releases its kinetic energy, converting it in heat. The kinetic energy is equal to half of mass times the speed squared. In this example, the speed is the Speed of Light, which is a gigantic number, and squaring it produces an insanely big number, so, even multiplying it with an amount as small as half the mass of a needle, you still get an amout of energy (and therefore heat) capable of causing that degree of damage.
I like this guy. Hes good at being corny, but not exasperating.
I'm sorry but I'm going to have to correct you on something. Everyone knows that ludicrous speed is faster than light speed...😂
it becomes a wantdle.
Damn who knew Needel could hit so hard
Where I come from... they hit the needle hard 😂
So... if mankind creates spaceships that can travel at the speed of light, then one mistake-if they don’t stop and instead crash into Earth-could wipe out all life on the planet?
💯 we would be toast. For matter of even a tiny amount of mass to be accelerated to light speed it would take, and therefore have, so much energy it would have the power to make changes to the atoms themselves, matter would be ripped apart... which would have an extreme output of energy.
But the people on the spaceship wouldn't have known any of the humans on earth at that point. If they did go out into space and come back at the speed of light, in their reference or perspective, we would have gone in fast motion by hundreds of years... if not millions of years, depending on the duration.
But I am not a physicist... just intrigued by the concepts. I'd have to refer this to someone with more education... but that was the way it goes in my head lol
🎉🎉😂😂😂😂🎉🎉🎉🎉🎉 bravo
Everyone always talks about how matter cannot travel at the speed of light. Nobody ever talks about how fast matter can theoretically travel. Do one on that!
at 11.47 the Toba erruption was really devastating that it created a mass hole and the entire volcano was destroyed. This gigantic hole spanding as big as Cuba Island and become Gigantic Lake called Toba lake, my hometown. thx for the Video
The speed of light is 300,000km p/s a needle is so strong at this rate.
It will dematerialize the moment it reaches the speed of light. We don't know exactly how fast enough and still less than speed of light, it will remain in material form for such a small and thin object.
It would burn up at the speed of light and never hit.
So it's so big, it reaches San Francisco? 😂 7:27
Nothing would happen because of Relativistic dilation. Einstein repeatedly said that singularities/black holes are not possible. He wrote in 1939 -
"The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (he was the first to claim that Relativity predicts singularities) do not exist in physical reality. Although the theory given here treats only clusters (star) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light."
He was referring to dilation/gamma. It's the phenomenon our high school teachers were talking about when they said "mass becomes infinite at the speed of light". This doesn't mean mass increases, it means mass becomes spread throughout spacetime relative to an outside observer. Time dilation is just one aspect of dilation, it's not just time that gets dilated. Even mass that exists at 75% light speed is partially dilated.
It occurs wherever there is an astronomical quantity of mass. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers.
Our own galactic center is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. In other words that mass is all around us. It's the "missing mass" needed to explain galaxy rotation curves.
Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has been confirmed in 6 ultra diffuse galaxies including NGC 1052-DF2 and DF4 to have no dark matter. In other words they have normal rotation rates.
I bet there's not a kid on earth that would mis a class like this..
The diameter of any stars photosphere is expanding twice the speed of light.
That's fun to ponder.
In my opinion, if a tiny needle used to sew the cloth can be made to travel at the speed of light and impact the earth, it will produce an explosion more or less the equivalent of 50-100 tons or 0.05 - 0.1 Kiloton of TNT. That is the equivalent of the energy released if the impact is strong enough to split every atom in the needle's material. You do not compute for the impact's kinetic energy model because the needle's material will not hold together upon impact but will instead vaporize instantly, and with it the dissipation of the kinetic energy. So in my opinion, that is the yield of the explosion and not as high as megatons or millions of tons of TNT like the large nuclear bomb that you said.
It would take infinite energy to move the needle to the speed of light!
The AEW wrestler Lance Archer uses the "Everybody Dies" catchphrase. 🤣
Burns out
E=mc²， needle no longer needle, it is just pure energy 。
the needle would survive the heat from the trip
I'm not a smart scientist but surely a needle traveling at the speed of light without being destroyed just would go deep into the earth... Now that would be one in a haystack
Wrong
The what if about this is, being a needle it would never be detected. Maybe? I know something moving at that speed builds mass, so maybe it would show up. Maybe it would create a black hole around it?
There is one thing faster that we know of... quantum entanglement.
LoL, his numbers are so vastly overstated as to be a joke. ½mv². That's it
This needle can kill Godzilla at this speed
So the needle would destroy just one side of the earth or just New York and nearby cities?
Liked for the Arthur Carlson quote
Why would scientists estimate the force when you can calculate it?
These theories are so fun to watch 😅😅
I hated that flash guy... the way he moves his arms.. shouldve had another guy play the flash
No. It would not create a tidal wave. Tidal waves are created by the sun and moon. The needle impact would create a tsunami. And there is one thing that can travel faster than light. Space/Time itself.
Marshmallows who knew
So I have something to ask now. What if the needle didn't followed, no law of physics, what will happen, and it travelled at the speed of light.
If approaching or reaching the speed of light gives a needle infinite mass does it become a black hole?
The shirts a little dark but good video.
Nothing can travel faster than light. This sounds silly.
Your statement sounds silly and btw your not a scientist so how do you know 😏 that's right you don't
Hi. Sorry to say but I cannot/do not agree with your thesis. 1: the needle has little to no Momentum (weight x speed) 2: it would melt and/or disintegrate upon entering earths atmosphere. I am more than willing to be proven wrong.
You should put the numbers up at the start ❤
Technology, that needle would not make it to Earth as it would gain too much heat to stay a needle. It wouldn’t even be solid and probably nothing more than vapor the about time it enters into Earth’s atmosphere.
So with invedo, you remove jobs of editors, creators and animators? Making them go with probably less paying jobs that they hate. Wicked!
The Aussie’s will be humanity’s last survivors? 🤦🏾♂️
05:05 "ackchyually", the expansion of space appears to be breaking that "rule"... afaik even neutrinos may be able to exceed lightspeed (D.U.N.E. will reveal that, if it is ever finished...)
Thank you! 😂 it kinda bugged me non-relative space-time itself wasn't included, or at least a mention of the hypothesis anyway 🤞.
Uh, this is not possible because it would require infinite energy.
Which is why it's called a hypothetical situation DUH 😂😂😂😂😂😂😂😂😂
between you blink one time and the speed of light, which one is faster?
Light
Light is faster. Even our thoughts, or the signal transfer speed though our neural & nervous systems, moves slower than light speed.
Speed of light is much much faster...when driving on freeway you can go about 20-30 ft when you blink, light would circle the planet twice in same span
I can see the difference of light between the lightbud and the floor, and it doesn't seem that fast... 🤔
4:37 Interesting. 🤔
That's not that fast.
We can beat this Goku! 🤣
5:50 An spacial giant Sling-gun! ❤
If the earth was flat... would Coke be carbonated?
Not to disagree with Einstein's theory I'm just having a hard time understanding the mass issue how much actual mass are we talking here? It's a paper thin small needle to push enough energy into a needle to get it up to light speed I think that the energy would disintegrate the needle or by the time it hit friction with our atmosphere for that matter. I guess there is no real world way to know because there is no way to push any object that fast with that much energy so far.
Let’s get rid of all needles and save the earth😊
Nothing with any mass has any chance of traveling at the speed of light. Mankind will never create anything that travels at the speed of light. Better off working on a teleportation device 😂
What if the earth started to spin backwards
I don't understand.
A needle has mass. As it approaches the speed of light it would have an infinite mass that would rip space and time. It would be the end of everything, not just the earth but everything.
Where am I wrong?
Because you don’t know for sure.
He loves destroying New York apparently lol
Reupload?
You mean 677,892,638 mph or 299,734,000 m/s?
what if humans were to detonate a 1000 or more nuclear bombs into space? to get to a few percentage to the speed of light, maybe 3%What would be the outcome or repercussions on earth?
I like his shirt!!
It would melt and vaporize immediately because the friction would be hotter than the melting point of the needle. Science problem solved
I HAVE BEEN QUESTIONING THIS FOR THE LAST FOUR YEARS or least if it hit a person my thought was either itd explode the person from the kenetic energy or would pass thru with mild discomfort or would almosy be like pepper holes due to spaghettification glad yo know im bot the only person that was curious on this now i wonder how much larger earth must be for a human to not fly off the surface if earth suddenly halted… granted its smooth surfaced and no trees or building n such
It would penetrate the earth if it could withstand the blow. Not much more would happen. Can’t disprove me with bogus
Evetyone on Earth would hear a loud shreak and we would feel a sudden jolt.😮
Just a puff of dust
That would be one fast turkey or bike
I think the needle would be driven deep into the earth l ‘ d like too see the math on the needle mass -traveling at that speed
what if this show was real ...
A black hole forms at the center of your youtube screen and consumes the entirety of existence Bc their tests tore the universe in half
It's would crack the Mantle of the earth
I would be one of the few survivors
Let’s do it I don’t see the downside of anything you said.
I call B.S. to this video. The needle does not have enough mass. Even if the speed increases, it's mass. Not enough mass to start with. Do the math it does not add up pal.
What if Chase hits earth at the speed of light? 🤔
Really there would be almost no effect. It woud just woosh through earth. People think that the energy would transform into earth fully.
No
why is there a goat skeleton in the behind is this why satanic?
Oh lord
Tell sun how into man
Why is there *everybody dies* text
🤔that much massive explosion with small mass i dont think so.
I just love the fact that this video ISN'T being narrated by some annoying artificial voice. Absolutely detest those things...
Bij 99.999999% lichtsnelheid is de massa ook enorm toegenomen ! dat veroorzaakt deep-impect.
Wat happens if u put tones of noz bottles inside a space ship would it survive or would it be a be a total disaster of destruction anyone thought of that? My question is probably nt maybe that should be interesting video for this guy
Calling bullshit.
Call of Duty Ghost
Why repeat the same info about infinite mass an energy with every scenario 😅
Just as I thought...make a video delete it later on and replace..been the norm for you lately
