I wish I could see the merger of two super massive black holes in person.

Funny thing is, you wouldn't be able to see it.

Burbon here!

He likes cleaning glass? Dude you're always welcome at my place!

What happens if the wave hits when he is cleaning the glass? The slacker in me says he should use it as an excuse, "Can't clean the glass, I am expecting a wave."

"If you notice, this one's the big one."

That's what he said.

Very much so, that was a very unexpected additional info at the end :O

I wanrt to see that video

Yes,that will ba a great video!!

still waiting for the jellyfish

What is his job, exactly? lol

would you say they are news of no gravity?

That's the problem to our media. The solar system and Earth got formed, life covered the planet, humans became dominant and all, then we only got the news now?

brah earth is 4.5billion years old its new compared to earth and we say the earth is young, i think the guy made a mistake tho waves don't travel at the speed of light... or do they? [Vsauce music, dum da dum te ta tummm]

+san kitty he didn't make a mistake lol! if you didn't realize, everyone here is being sarcastic!

@San kitty Gravitational waves do travel at the speed of light. (Unless gravitons have rest mass, which they probably don't, but if they do they're extremely light, and would be traveling at very very close to the speed of light like neutrinos)

OzcarMtl but teaching is the best way to change the world

Don't be disparaged by assuming you are not good enough at mathematicss. I myself thought that I would fail because I'm bad at math (and hoped my friends could somehow carry me through the exams). Now I'm finishing up my physics degree and realized that I just needed more excercise, the fear of not being good enough is long gone. Also, you can go far beyond teaching physics in school after you studied. Research being one option of course, but many companies rely on physicists as well.

OzcarMtl man I don't know. I think most us are good at maths nobody is born with what should I say "a maths mind", we need good teachers with open mind who can make people think they can do anything. we are just ridiculed in schools some people won't understand in the same way everyone does. so there's a problem. there is a need of good teachers who can fire our interests.

Math becomes less difficult when you round everything to a power of 10

Kylar Stern yes.... more jellyfish plz

Yeah, using a neural network to figure out how we think with relation to one thing and then deconstructing the neural network could provide some really cool insights.

Kylar Stern me too. I was looking if he put out a video on it. He didn't 😕

Warren Reyes hopefully in the future!

yeah where the hell is A.I. Jellyfish?

lol

hes a fanboy xd

the first comment shows true commitment. its truly the single biggest. longest run meme of all time. It wont die aslong as youtube exists. thats something truly amazing right there.

Sophie Matthews thanks for the lecture, dude

lol

Something tells me this guy always looks like that though, lol.

Yeah - always wired, tired and full of coffee, Diet Coke, or pure nerd juice - but he's cool

From what I can tell, that certainly applies to techs, adjuncts, and G-students. However, most PIs like sleep.

High people tend to look sleep deprived.

They didn't get high up by sleeping

whats the answer

sounds like a swing/jazz sinatra song ;D

There was a young lady named Bright Whose speed was far faster than light; She set out one day In a relative way And returned on the previous night.

Way better than expected. And btw the Wright bros. invented the flying car in 1903.

@@ZachariahMBaird not the same car obviously - not the same context

@@giannibleya7690 it still flys, has wheels, can carry people, I bet you could make a plane that looks like a car.

@@ZachariahMBaird still not the same car man. You just don't get it. Planes are to heavy to accelerate, can't drive ordinary people every day, and so on

@@giannibleya7690 and cars are too heavy to fly

Yeah, it's the same guy.

same guy from what ?

XxaaccoolL Derek made another video with Rana on gravitational waves before.

Yeah. the first video introduces him as Rana. Veritasium also calls him Rana in this video.

I suppose the better question is, why aren't there more fish on the chalkboard?

Ril M All I see on there is chalk.

Great chalk reef died, a lot less fish now.

Science

I'm guessing someone was drawing alphas and got bored

Jimin's Pinky Finger I'm willing to bet that sound right as the footage cuts at around 4:20 was the sound of it just by how the guy described the noise

You did...1:32 Bvwoooom.

Micheal here! Buy RU-vid Red!

LMAO

brilliant musef

hey vsauce ! Michael here

I would say yes, they have to be certain that it is what they think it is.

Before they could publish, the paper probably had to undergo some serious peer-review.

Pretty much. Hence why he talked about "secret" signals they just can't talk about yet. Scientists tend to only officially mention things once they are confirmed with extremely high orders of precision. They're like the opposite of gossip magazines. ;-) Essentially, be prepared for lots more announcements of gravitational wave discoveries down the line.

lol, some actually takes years to verify

Because there are so many possible sources of background noise (trucks passing by, electrical currents in power lines...), they need lots of data analysis and such, which takes a long time, to rule this out

its live feed of history , other planets could be detecting ours

Breakfast221 What i wonder is how they picked up sound. I know sound isnt picked up as sound waves but isnt is still not as fast as light. And its 3 billion lighy years. I just dont seem to understand it. Any explanations to help me?

Your picture made me wipe my screen

Oh god, it started with a spider, now this, whats next? :D

Got me good

Yea but that's only because Einstein was a racist.

pasta0328 I heard he was a white hole supremacists.

Boom!

Lol Kay What's tripping you up?

Waves

Lol Kay why dont you understand???

VirulentShadow good catch

Hahahaha 3,000,000,000 billion years is a lot more than 3 billion years.

They have been proven to exist by gravitational effects on nearby stars, gravitational lensing of light behind them and the movie interstellar. Just kidding. But honestly, we have a lot of proof of their existence, this just amounts to further supporting evidence. We have had pretty solid proof of black holes for a while now by mapping the movement of stars around the center of our galaxy. The star's movement, speed and orbits can only be explained by a massive gravitational force around which they are moving. Although we can not see them, we know they are there. Also, we have seen gravitational lensing of light from distant galaxies by black holes. The gravity of the black hole has an effect on the photons passing by it, bending their path, and we can see the effect in their light pattern from our vantage point here on Earth. As far as gravitational waves moving at the speed of light...I am no expert on this topic, but I believe it is because they have no mass. Gravity is the bending of the fabric of space, so I could be way off here, but I believe that this bending of spacetime still has to obey the cosmic speed limit, so it can't move faster than the speed of light. With no mass to slow the energy moving the waves down, any amount of energy would move the waves at the speed of light, at least in a vacuum. I am much less sure of the last answer than I am of the first few. I think Isaac Newton thought that gravity moved instantaneously, but Einstein's theory of relativity claimed it moved at the speed of light. And I am pretty sure because gravity has no mass, that it would only move at the cosmic speed limit. Not sure how the expansion of spacetime over long distances would affect gravity and gravitational waves. Would it do something similar to light that redshifts? Meaning that the wave amplitude declines because the waves gets stretched out. I believe it would, but that wouldn't slow it down, it would just make it harder to detect, or maybe look differently than it does.

Good answer! Thanks for taking the time to reply :)

The fabric of space actually can go as fast as it wants, that is why the alcubierre drive could actually work, since the spacecraft is bending space to go faster then light. Now, I don't know if gravational waves are bound by the cosmic speed law though. All I know is that the alcubierre drive can make a spacecraft go faster then light because the spacecraft itself isn't moving but space itself is.

Gravity is bound by the same laws of causality as light, matter, and all other energy. Anything that happens in the universe can only ever effect something else, no matter it's distance, at the speed of light. This is causality which is actually way more complicated than it sounds and way more simple than it can be made out to be. The theoretical Alcubierre drive doesn't allow space to travel at any speed, it basically compresses space in such a way that you can travel through more of it at once while traveling at zero speed because you are simply warping the fabric of space around you. In fact, due to expansion of the universe, space itself either is or will be traveling faster than the speed of light so eventually all of the light we see now from galaxies will be unable to reach us and the sky will go dark over the next few billion years. I am just a laymen myself though and by all means don't have the time or space to explain the very intricate inner workings of astrophysics and quantum mechanics. For a MUCH better, and accurate, explanation look up PBS Space Time on youtube. They have videos explaining causality and space warping and everything else you might have questions about and they explain them in great detail. Just don't be afraid of the maths, they're pretty good at explaining it in laymen enough terms.

Gravity is not instantaneous. It has to follow the laws of causality just like light and matter and energy. Check out PBS Space Time on youtube for an in depth explanation of causality.

Yeah, because science isn't political. Totally unbiased and impartial. It's easy to tell by all the grant-funded experts saying exactly the same things, over and over. No politics there, to be sure.

E. Lectricity I dont know what you are thinking, but sitting in a room crunching numbers and creating theories is not political xD.

Civilizations of the past, time and time again, thought they understood the universe in it's entirety, and it destroyed them - every single one.

SamStam12 How do you know that??

It is, when your number crunching costs are not self-funded. Who put up the money for the research? Who decided who got to award the money for the research? Why couldn't the science fund itself, based on merit alone, rather than on someone's arbitrary decision to fund it? Political. Of that, there is no doubt. Or is there a bottomless pit of cash available, made up at a moment's notice, to anyone who practices the science of dogma in today's age? What if someone who has a completely opposing view to those bastions of science who all sit on the same side of the fence within our vaunted institutions suddenly sought funding from the same politically sensitive sources? Would their funding come through? What if this new research upset the entire paradigm? Right, no politics here, gotcha.

Does Curry make gravitational waves?

It does! Even if all you do is stir it! Just very very Very tiny ones.

My physics professor is called Kumar.

He actually looks a lot like Irrfan Khan, a famous Indian actor. You might know him from Jurassic World and Life of Pi.

Neural networks are a system of interconnected artificial neurons that, have a bunch of inputs, outputs, and a load of hidden layers. You can weight the connections based on results. You can effectively "train" them to respond to data in different ways. There are a few teaching methods, but this something more worthy of a quick search than some bloke's RU-vid comment.

okay, ill

Or watch the hundreds of videos, or read the dozens of papers about the subject. Why should every video be self-contained?

Not really. There is no evidence that gravitational waves are quantized or exhibit wave-particle duality.

Okay thanks.

Well it is different, they said this one they don't believe was from a binary star system, like the others were. And the signal was detected far stronger. And it proved a previous inclination.

Other event Other discovery of an gravitational Waves for scienc the secound is as importen then the first. Much more importent would be somting thats is agenst existing Theories so we can make new ones that are better, thats the way scienc progress not by knowing how it works, rather how it for sure not work. If an Theorie is True in seemingly all cases we know, were stuck.

Spencer Twiddy isn't a Discovery supposed to be implicitly new?

@FatDuckbreak at leatst for me its new

Wouldn't any new information - regardless of what it is - qualify as a new discovery? :thinking:

Hettor MachCesar nice meme

_Wow!_

Hettor MachCesar *Coverage

Hettor MachCesar you heard it here first people.

bringing politics to a science video...way to be that guy lol

if u dig into how 1st gravitational wave detected then it would be a lot easier to understand what is going on here

rahul singh if you dig into jokes then it would be a lot easier to understand what is going on here...

no

When two Black Holes begin to merge, they do so after revolving about around each other and gradually coming closer to one another and when they finally coincide, a huge wave is produced due to their collision.

um... gravity.

TheSliderBy That's the Dunning-Kruger effect :)

I looked that up and the Dunning-Kruger effect is a cognitive bias where people of low competence overestimate their abilities, and people of higher competence tend to underestimate their abilities. Maybe I'm missing something, but that doesn't really seem to relate to what I was talking about.

I don't know if there's a specific name for it, but learning more does seem to have the effect of also revealing how much more there still is to learn.

Every answer raises more questions. I dunno 'bout chu, but I find it reassuring; maybe boredom can be staved off yet.

R Pan Yeah.. proud of nepali

Arun Sapkota how do you know he is nepali?

You have Anish Giri too, by the way. but does it actually matter in any way?

+C Popular name here (Nepal) too. But regardless of his place of birth (even if it is Sri Lanka or Nepal) this sense of pride is dumb. What contribution did his home country really have? The credit goes to him and place where he got his knowledge, tools, and environment to flourish.

+C Preliminary googling says he's Bengali. lololol
