Thanks for watching, Super Nerds! This was a fun one, as many others have talked about these phenomena, but I've never seen the math on how to make some of them "work." See you in Footnotes. -- kH

Kyle stop telling us how we can exploit the Universe's physics engine. The devs won't like that.

"I cannot stress enough that I'm not a supervillain" Don't worry, Thor, I trust you.

“I’m not a supervillain.” *looks at next video* “Should we nuke Mars?”

Kyle: I’m not a super-villain Also Kyle: Lets make a giant space guillotine.

Kyle: "Here's why you DON'T want superpowers." Also Kyle: "Here's another way I could kill you with science, you non-superpowered nerds." TOTALLY not a supervillain.

The faster-than-light guillotine. *Louis XVI has left the chat*

When will the "Let's put rockets on our space guillotine." t-shirt be available? Asking for a friend.

The "speed of dark" has been one of those things that have fascinated me for ages, you supervillain you.

And the barman said "sorry we don't serve tachyons here" A tachyon walks into a bar...

"I'm not a super villain, but what if rocket guillotine "

Kyle: * Makes a FTL Guillotine * *FRANCE WOULD LIKE TO KNOW YOUR LOCATION*

I really like the fact that you threw in that pushing on the scissor handle would only propagate the force through the scissor at the speed of sound. Not that it really mattered to the point you were making, but taking the time to mention that shows a care for accuracy, even while discussing ridiculous things, that is just really refreshing. Kudos to you and your team.

"I'm not a Super Villain, i swear." Sounds like something a Super Villain would say...

"We wouldn't have a planet chopper anymore." Why do I hear disappointment in Kyle's voice?

Stuck with a phantom German accent? You may have Einstein moustache.

Are you sure about that "speed of dark" thing? Because it sounds awfully similar to "let's destroy the sun and see how long it takes for people on Earth to notice", which of course does obey the speed of light. Not that I've personally destroyed the sun...

Kyle is definitely not a super villain. He is clearly informing everyone of the potential dangers that comes with a greater understanding of science. I mean, its not like he is using these videos as a subtle way to threaten any potential heroes that might stop his rise to ultimate glory or anything. Totally not evil in the slightest. For the glory of SCIENCE!

"Answer the phone you coward." is my new favorite way to call people.

Kyle: " I have a new idea for a guillotine" French ppl: " tell me more..."

“We could make make this with today’s technology, I’m not saying that we should, I’m just saying that it would be totally awesome” This man is truly the best

"I'm not a super villain. And if anyone knows it, it's me." The thing that makes a good villain is that they don't think they are the villain. ;)

Kyle isn't a supervillain, he's the guy that makes their plans and the weapons.

I was so intrigued by all the science within the first 8.5 mins that I totally forgot that this video is supposed to be about a FTL guillotine until he finally mentions it

Me: space guillotine is the coolest idea ever Kyle: LET'S PUT ROCKETS ON OUR SPACE GUILLOTINE!!! Me:Oh...My...God

5:54-5:57 "The speed of dark." Hey Vsauce, Michael here.

Kyle Hill: Into the Voideyverse (2019)

0:43 That is a sick animation, and I think it goes underappreciated!

3:40 Evil Kyle eliminates his good counterpart (2019, colorized then decolorized and then colorized again)

I immediately thought of vsauce's video on "what is the speed of dark?" when you mentioned it.

Nobody: Kyle: what if you built a rocket-mounted super massive space guillotine?

The chop on the stash and the look after was amazing.

Kyle: Calculates very complicated equations like it’s nothing. Also Kyle: “As the Sun rotates”

my dad saw me watching this video and asked y thor was making sciencey videos

You have shown what I always imagined Occam's razor to be before I looked it up. Thank you.

"I'm not a supervillain" Me: yeah ok. Keep telling yourself that.

"By Feynman's follicles, you scared me!" That's a new one.

"Oh, I was roaming. Oh, shi-" There goes 10 years worth of salary for that Mars call.

I did a time dilation calculation on those near-light-speed protons at the LHC, and it's effectively 1 second = almost 2 hours.

7:15 “You probably used a scissors before-“ This got me. 😂

My little cousin is an infinite energy source, that little bastard doesnt seem to slow down ever

Man I love your channel i like your energy

When you keep denying that you’re not a super villain - - - you’re a super villain 😂

Sometimes I like to imagine Kyle is at the thanksgiving table doing these rants/speeches and everyone is too polite to tell him they don't care so they just smile and nod along. Loved the episode btw

I've never heard someone say "a scissors"...you're my favorite.

Eusten:" We need an orbital strike towards asteroid shower gamma quadrant, over."

"Scissors! Not planet cutters!" -Kyle Hill, 2019

Kyle: "Get out of my future past!" Kitty Pryde exits chat

Light speed guillotine? Sounds like something I'd want to get my neck under.

I'm glad to see this video. The idea occurred to me many years ago, so to see it confirmed makes me happy. However... Let's say you have two rigid rods that are a light-year long. One is stationary from your frame of reference. The other is parallel to the first, but it's moving toward the first one. They will collide. You're right at the midway point, a half a light-year from either end. From your perspective, the collision will NOT be simultaneous along the length. The contact point closest to you will collide first. The farther away from you the rods are, the longer it will take for you to see the collision. The rods are curved, from your reference point. It will take a half a year for you to see the ends of the rods collide. "Now" Is local. There's no such thing as absolute simultaneity. It doesn't even make sense to think of the second rod moving as a single inertial body, when it's a freakin' light-year long. What happens at one end takes a year, at best, to get to the other end. Imagine you're a light-year long. What's going on at your feet is a year away from your head. You don't exist in one time zone.

Han Solo does know what a parsec is. The drive in his ship allowed him to use a hyperspace lane that was closer to a black hole than the rest, he didn't have to go around it as much, shortening the distance. He literally did the kessel run in fewer parsecs.

To quote Terry Pratchett: "Light thinks it travels faster than anything but it is wrong. No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it."

Man I remember trying to race with light in my room by turning on the lights as im running through the room when i was little

*"I'm not a super villain"* - Kyle, Because Science of Doom

Super kool. Love the enthusiasm.

11:27 "what if we put rockets on our space guillotine" xD 12:00 I'm a bit concerned about him getting so excited about this "We could build something like this with today's technology" xD

"Not planet cutters" Sure Kyle, sure not sounding evil at all

You sir, are cuter than a puppy and a kitty trying to climb into the same sock! It seems unfair somehow that you should also be so clever, but such is the world that we find ourselves in. I'm new to your channel, but have been immensely enjoying your content so far. I think your going to be my new favorite internet time assassin! I especially loved your video on magic the gathering powered computers! It was an awesome concept! Take it easy, W.Peace

Love the science. Love the passion. Love the impression.

Kyle: I'm not a villain Every musician: But your theme music is a tri-tone. Historically known as...the DIABLO chord! 🤯

2:31 Kyle mentally high fives himself for that pun without skipping a beat in the script. Nice.

"The speed of dark" is the best explanation I've seen of how a tachyon would work.

Hey Kyle, on the subject of the theoretical spotlight covering the moon, if one where to make a blinking strobe effect across said spotlight at a shutter speed fast enough to make the shadow ftl, what would that look like?

"Mostly because I read a paper that did the same thing" Ah, a true scientist: Cribbing off someone else's research since time immemorial.

3:40 so that's how Super Villian Kyle killed Super Nerd Kyle and took his place 😮

Every time I watch an episode of these, I change my own past beliefs and understanding of my own future, because science.

This will absolutely and unequivocally be my final year project proposal. I dont care where the funding comes from. I will do this.

So what did we learn today? Never give Kyle enough money to build something for Space... He is NOT a Supervillain!

OMG the ads are the end...this is really the best KZfaq channel.=)

This Guy is SO Awesome,I literally can't stress that enough!

Thanks for narrowing down the coordinates to your secret lair a bit, it seems S.V. Kyle is on Mars (which kinda explains the terraforming Mars ep.) and his scientist clone/twin/pawn is on or near Earth in "the void" (Rods from God ep.). Poor Void Kyle, so easily replaced whenever the "original" KH, or an evil-er(?) VK from the future deems it necessary. 🤔 I HAD a question but unravelling the location of your lair got the better of me. Oh well. Anyways, love the show! ...and I'm not just saying that to keep you from sending those Laser Bees after me. **shudder**

ATTN KYLE: I'm sooo so sorry for doing this but I've gotta ask, "Why sooo sirius?" ... Because Science

Love how you make your videos in the void.

This needs to be a Mythbusters special!! Bring Adam and Jamie back for this one off.

Super villain?! I always thought you were Thor wearing a Kyle disguise

So when I turn my head from the Moon to Sirius the center of the plane of my sight(or the end point of the line of sight wich points to the Moon then Sirius) moves 8 light years within a second. That means I have FTL vision. Cooool. (Next Because Science episode: "why you don't want FTL vision")

Do you think you could do a video on what would happen if the human body burned 1 calorie per second 24/7? One of many random odd discussions I had with a buddy and I said "You know what.. I bet I know who would have the answers and this sounds like something he would have on his channel". Thanks for all the awesome vids! Keep them coming! =)

Kyle: ...rockets on a space guillotine! Mermaid Man: EEEVIIIIIIIIIL!!

"Change your perspective a bit." You mean take a certain point of view?

Ok now I'm convinced Kyle is actually some comicbook villain but in real life

Wow, great Einstein impression! (I take that back) Great Stanley Tucci from Captain America impression!

Awesome video Kyle

For the moon example: That seems to be the general *intuition* of how this should work. However, imagine light moving like a stream of water. If you block a powerful hose with your hand that's pointing at a wall, say, 20 feet away... the water between the wall and the hose that left the pipe BEFORE the stream had been interrupted still reach the wall EVEN THOUGH your hand is still in front of the pipe. Try it! The analogy works with the moon as well: if you, say, shine a laser or bright light on the moon (and for the sake of argument, assume it lands and reflects/absorbs, etc.) then moving your hand across the beam to block some of the light from reaching the moon would have the same effect as with our pipe analogy. Even though your hand (or whatever other implement) has already blocked some of the light, the moon still receives the photons that left just BEFORE the block was implemented. During the photon's travel and reaching the moon, the hand would still be there, and the photon would still bounce off. This would therefore mean the speed of "dark" is roughly, if not exactly, the speed of light. Did... VSauce have a video on this?

"Im not a villain" you would say that if you were one... hmmmmmm

one side with like 9 blades spaced apart and the other side with 10, place them so that they do not collide when passing, then put a wedge which is the exact shape of the intersection point in the middle, accelerate the two objects and see if the wedge gets pushed really fast out of the way

Dude. Im still thinking about this. HOW STRONG ARE YOUR KNEES!!!! You always bend your knees alot when explaining. I love these videos btw!

I can't unsee that the Because Science Logo is inside of an upended triangle, resembling a Super "V" for "Villian". It was there the whole time...

Me: Super villian? Kyle: *Super villain?* *Me: Yes.*

@because science QUESTION you said that 2 particles that were entagled if seperated would apear to instantly comunicate with each other after being measured well that got me thinking about the massive delay bettween mars and earth of about 16 min. could we use 2 particles that were entangled seperate them and then use them as a way of information transfer to bypass the speed of light limitation on data transfer or is this not possible and if so why

"I'm not a Super-Villian..." is EXACTLY what a Super-Villian WOULD say to throw us off the scent. The scissors example broke my brain.

i mean he said it himself, he CANT be a supervillain. nice one kyle

Hey Kyle, love the show! A couple of additions I'd like to make! (Not corrections this time, lol). You had mentioned the expansion of the universe, and yes, you're right, there's nothing that stops space itself from expanding (or contracting, or both) at superluminal speeds. This fact is what led Mexican theoretical physicist Dr. Miguel Allcubierre to develop his Alcubierre Warp-Drive. (Yes, inspired by the star-trek warp-drive, but designed in real-world physicis.) This particular construct works by creating a bubble of space-time around a vehicle, and moving that bubble along a wavefront of expanding and contracting space-time, at speeds that can exceed that of light. His original calculations for a spherical field required energy-levels exceeding the energy of all matter in the universe though, so that wasn't very helpful. Later-on various physicsts (Such as Dr. Harold White from NASA's Eagleworks Laboratory) have managed to twist that sphere into a torus (donut) shape, and reduce the energy-requirements down to only the amount of energy in around 900kg (a little less than a tonne) of matter. Meaning this is actually potentially feasible, if not highly difficult, and implausible, just NOT impossible. Granted in order to produce these bubbles, you'd need access to something that generates negative energy, perhaps some exotic form of matter, but we're not certain on that point. (However, given the expanding universe, negative energy is a thing we know HAS to exist, we're just not sure how... yet...) Also the design as it is may have some issues when attempting to travel at superluminal speeds, such as instantly incinerating everyone and everything inside, destroying the universe through fluctuations in the vacuum energy state, and/or breaking causality in a time-related paradox. But those are small potatoes... lol. And this is just one potential suggestion of actual superluminal (Faster Than Light) propulsion that works with physics as we understand them. There are also wormholes, quantuum-entangled teleportation, and also higgs-field inverters, but that's a bit too much to talk about in just a random comment. But yeah, just sayin' that there really are some ways that we've thought-up where things can (and DO!) exceed the speed of light. It's a fascinating topic, and one worthy of the show! Keep up the good work, my totally-no-a-supervillain friend!

The reason why can be simplified : "c" isn't the speed of light, it's celerity. And as such, something with mass can't go light speed and something cannot not move (absolute zero). Energy and speed is proportional, and since speed = time x distance, you can derive distance, time, speed and energy with each other. THAT'S what "c" means, not just "speed of light". It's a graph.

"Entangled" *JADA WANTS TO KNOW YOUR LOCATION*

12:09 Dude, did you all hear that giddy catch in his voice? He was really enjoying the prospect of the idea of a 3-mile wide guillotine. It's confirmed: he's a super villain

Roaming on a hard wire phone, that bill would break your bank account.

thank you TBD, for programming this

Han knew what a parsec was. There was a black hole in the middle of the run. To get past it, the faster your ship, the shorter the distance of the required arc around. To make the run in shorter distance was the brag. They did leave out the issue of time dilation, though. Better have some immortal customers waiting for the delivery.

Love the show so much I had a weird sleep-aid induced dream that I met science thor and he's totally not a super villain thanks NyQuil Also those scissors got dangerously close to your hair be careful!

Yeah Kyle, we've all read Nick Herbert's book; 'Faster Than Light: Superluminal Loopholes in Physics.' before. Nice presentation of basically all the best parts of the book. I think you deserve a 'SuperNerd' or breaking this down even further than he did for us plebians. Herbert and Kaku got some chops when it comes to making string theory and superluminal quantum phenomena palatable. You're like their internet successor in a way, making it fun.
