Neutron Star Merger Gravitational Waves and Gamma Rays
Vložit
- čas přidán 15. 10. 2017
- The merging of two neutron stars was detected by gravitational waves and then by telescopes in all parts of the electromagnetic spectrum. This is a historic detection as it demonstrates:
- the first gravitational waves detected from inspiraling neutron stars
- the first joint observation by gravitational wave and electromagnetic wave astronomy
- identification of a gamma ray burst in conjunction with merging neutron stars
- how gravitational waves and gamma rays can be used together to locate their source
All evidence so far indicates that the data support General Relativity.

Jets and Debris from a Neutron Star Collision
This animation captures phenomena observed over the course of nine days following the neutron star merger known as GW170817. They include gravitational waves (pale arcs); a near-light-speed jet that produced gamma rays (magenta); expanding debris from a "kilonova" that produced ultraviolet (violet), optical and infrared (blue-white to red) emission; and, once the jet directed toward us expanded into our view from Earth, X-rays (blue).

Virgo Helps Localize Gravitational-Wave Signals
Sky localizations of gravitational-wave signals detected by LIGO beginning in 2015 (GW150914, LVT151012, GW151226, GW170104), and, more recently, by the LIGO-Virgo network (GW170814, GW170817). After Virgo came online in August 2017, scientists were better able to localize the gravitational-wave signals. The background is an optical image of the Milky Way. The localizations of GW150914, LVT151012, and GW170104 wrap around the celestial sphere, so the sky map is shown with a translucent dome.

Variety of Gravitational Waves and a Chirp
The signal measured by LIGO and Virgo from the neutron star merger GW170817 is compared here to previously detected binary black hole mergers. All signals are shown starting at 30 Hertz, and the progression of GW170817 is shown in real time, accompanied by its conversion to audio heard at the end of the movie. GW170817 was observable for more than 30 times longer than any previous gravitational-wave signal.

Showed this video with amazing science discoveries about the universe to my mom and all she said was : "this guy likes orange decorations"
It's not like it's something that will directly affect her.
This is a very niche subject
Wow. I didn't even notice the orange stuff until I read your comment. Shows how our own experiences bias our perception.
francisco chinchilla resende We don't share the same mother do we...😂😂😂

And that is the only usefull thing to say about this vid.
That's a good observation. I didn't notice that at all.
Hi Derek. I'm a 19 year old from South Africa and I've always known that I wanted to study Physics at university, but I could never decide between particle physics and astronomy. I've been following you for a while and love all you videos. This one, however, has made the decision for me. I am going to study astronomy so that I can be part of these discoveries in the future. Thank you so much for making your videos and inspiring a generation of scientists.
Miles Kidson all the best. We all hope that one day Derek will make a video on your discovery.. :)
Yeees
See you soon!!
Let's make some amazing discoveries!!!
Study Astrophysics and get the best of both worlds. This is a fantastic time to be an astrophysicist. Not only to you get telescope time on incredible instuments both earth based and satellite based in the optical (keck, hubble and so on), the infra red (the amazing new James Webb which can collect seven times more light than Hubble and collects light more towards the infra red permitting it to see through some of the interstellar dust) and huge arrays of Radio telescopes (which deeply penetrate dust) and now with LIGO and the Italian Interferometer we can observe the gravitational waves that Einstein's equations predict. On top of all that, astrophysicists examine hypotheses (and eventually theories) as to the mechanisms that produce these extraordinary things that we can now observe. Work hard and stay focussed (no pun intended) and who knows, you may one day have a career where every day is a joy. I wish you well.
Hey, curious to know any update after three years? Where have you been?
@@akashdhanwani6638 Woah I forgot about this entirely. How did you even find it?
I'm currently in my third year studying physics and applied maths, not likely to go into astronomy but more interested in particle physics. Thanks for reminding me of this though, I'm going to watch it again to see what it was that convinced me properly.
Wow! This was super well-presented! Great video, Derek! :)
I like how this channel becomes the official announcer of LIGO eveytime we detect gravitational waves. Awesome!
Well to be honest if i wasn't for Veritasium I would have no idea until weeks later & something of this nature I like to know about right away. You guys rock & the rest of the world should know too lol! xD
It was on the news where I am. They made it seem like the first gravitational waves we've measured. They also called the gravitational wave the sound of the collision.
zacozacoify LOL really?, news readers should make some previous research before talking in front of TV.
No -- Gravitational Waves Have Not Been Observed | Space News

This happened 130 million years ago, this is old news, tell me something new
God: Behold this universe, which We hath created for you 13.8 billion years ago!
Man: Yeah... but what have you done for me, lately?
N Marbletoe We don't even know whether it exists now or not
its just a simulation
Awesome 😂😂😂
Albert Einstein had worked with Velikovsky during the last 2 years of his life,,, and was planning to create a research program to prove Velikovsky's theories. When Einstein was found dead had a copy of Immanuel Velikovsky's "Worlds in Collision" open on his desk!!!!! This is a direct quote from The man himself Einstein said when speaking to the detractors of Immanuel Velikovsky's theories THIS!!! "Great Spirits have always encountered violent opposition from mediocre minds" THIS IS PROOF THAT THE MAN HIMSELF SAW THE TRUTH IN HOW THE ELECTRIC UNIVERSE SAYS THE UNIVERSE/SCIENCE WORKS AND HOW ANCIENT HISTORY WAS DIFFERENT THAN WE HAVE ALL BEEN TAUGHT
Pin pointed within 11 hours by optical telescopes.. *mind Blown* The Scientific communities in these fields are massively under underrated, under appreciated... and most definitely (still) under funded... ...just 11 hours!

*Wow ...130 million years ago two neutron stars merged and humankind witnessed it 130 million years later !!*
That part shouldn't really be impressive because well that's just how light works.
Call me a kid.. but its still impressive to see something that happened 130 million years ago 😁
We're all kids, Eddie, and we always will be.
Not exactly.
Space itself is constantly expanding. So it happened somewhat less than that time.
The cool thing is, from their point of view, this time was probably very different from our time!
Imagine there are still people out there believing the earth is flat...
exactly.
They're either Trolls or Idiots.
Either way, not worth anyone's time.
Imagine there are people who believe that all visible universe with 200 billions of galaxies and each one of them with 100 billions of stars (and still not visible, with maybe infinite number of more), is created by some guy who descended to Earth and showed few simple illusions like transforming water to vine etc.
I've never seen any christian who claims that jesus created the universe. That's kind of a strawman.
A simpler world view for a simpler folk...
Edgar Allan Poe agreed, but believing they are actually reading gravity waves from a gazillion miles away by reading a difference of the thickness of a proton is actually more embarrassing. What a waste of money this experiment is.
Derek is really good at resonating his excitement through the video to make the viewer also excited. This is one of the reasons his videos are fantastic.

I love the sheer joy and passion you display in talking about this. Your excitement is inspiring. Thank you.
As I mentioned when I met you last week, you make videos on topics I would have never thought I would find interesting. Love it!
He realy is excited at the end how much science that has to come with this new technology
130 million years ago......😱😱😱
Yes isn't that amazing?
Geez... talk about old news, lol
And to think, everything we see and hear, is the past
We just witness planets being killed -_- everything we see in space is already dead. Thank God we're still alive :)
Is this really 130 million years ago? and the gravitational way just pass right thru earth?
I love your bigger, very well produced videos of the subjects where you get to travel and meet different researchers.
But this 5 minute format to put the viewers aware of current events is also phenomenal.
Although this is a very important discovery, we need to avoid phrases like, "Now there can be no more doubt" because that is just not how science works. In science, we always leave open the possibility that we are wrong, and that our beliefs will have to be revised.
Perhaps a better phrasing would have been to say "Now there can be no more REASONABLE doubt".
yet
That is true
agree
Thank god someone else knows how to science....
Loved the way you explained all this. You create interest in subjects that are not popular but can prove to be helpful information. Great work! Thanx for the vids.
XxZ 2 haha! Relax brother. I know this is a wonderful discovery. By saying "not popular" all I mean is that there are still millions of people who don't know the importance of all these discoveries and the effect they have on science and world (including the way humans live). And remeber I also stated that through his videos, this guy from Vertitasium explains all this very beautifully and makes it available for all those who are still unaware of such marvelous discoveries!!

Hey,
I wanted to tell you what I really like about your Videos.
Although you're talking about very complex things in a lot of your Videos you are capable of deliver them as simple that a non scientist can understand them. But you explain enough so I keep thinking about the topic when I finished the video.
But the most important thing for me is that you deliver the things with such a fascination. In every single video I can see that you have fun creating and talking about the content.
Anyway greetings from Germany.
totally
Last time I was this early gravitational waves haven't been discovered
So about 2 years.
You're one of the few people I find really relatable. In the sense that we feel wonder and stare in aw at the universe. Yet wish to understand every detail of the magic we see. I'm really happy Micheal Stevens recommended your channel. It's by far one of my favourites.
More of such episodes Derek, it's in these you really shine imo.(highly fascinating and addictive)
There is no doubt that we are living in extremely interesting times full of amazing discoveries! I'm really excited about the future!!
I get goosebumps when a new discovery is announced. Yay science!
I know that feel, bro!
This is like living in the tower of Pisa when Galileo was dropping cannonballs. It is a new era in science and we have front row seats!!!!
Crazy. Thanks to you Derek, now I clearly understand why this discovery is so important. Cheers from Belgium ;)

And please like me on my video,
The universe is fascinating. Scientists believe that there are planets made entirely of diamond. Now that would make a hell of a wedding ring.
But.
We "always" knew that heavy elements were made in supernovas, because a star cannot use iron in the process of fusion(fusing hydrogen, helium, carbon etc. CREATES energy, fusing iron REQUIRES energy.). So when the star eventually runs out of fuel, there is no outward pressure(core heating up the gas) to counteract the inward force of gravity(mass) and so the outer layer of the star gets pulled inwards and flung outwards again(like dropping a tennisball on top of another tennisball) producing a shockwave. And some of the energy from that explosion is being used to fuse iron and heavier elements.
We've known that theoretically for a long time befor
Excellent review of the discovery. Thank you!
thanks for coming back.
Why am i so excited about this, like i am literally jumping right now.
meth?
don't be .. czcams.com/video/SFJjrD5pq_I/video.html
Yeah, I was really blown away when started talking about how we found what part of the sky it took place in and narrowing it down to a few galaxys.
How can you jump and type at the same time
WazzupKMS me tooooooo
wait a second.
1.5 second gap...that's seems like an awful long period of "silence" between the actual merge event and the GRB event. why the pause?
I thought it was crazy short for 2 pretty big objects merging.. the gravitational waves are strongest right before the merge and the gamma rays likely somewhere in the middle of the merge or the end.. just my guess tho.
My guess is it's because gravitational waves move at the speed of light, but the actual impact of the neutron stars on each other have to be transmitted from one neutron to the next, so it's limited by whatever is the speed of sound on neutron-matter at the various densities in neutron stars; basically, it took some time for the shockwave to go thru the neutron stars.
Just to give you an idea, at the speed of light, it would take about 4.6 seconds to go across a distance equivalent to the size of our Sun; the speed of sound in neutron matter is probably slower than the speed of light in the vacuum..
Light can interact with all the dust and stuff on its way, slowing it down, whereas gravitational waves interact with everything very weakly, so it goes right through. Light being slow is quite common in astronomical observations, for example, neutrinos are also known to arrive earlier than light in events that emit both, because neutrino hardly interact with anything.
The visible light emitting component (the explosion) of the collision is preceded by the gravitational wave emitting component (the accelerating binary orbit)
One hypothesis I've heard: The GRB detection was delayed because the jet wasn't pointed at us, but it hit some gas/dust/debris orbiting the neutron star pair, and reflected off that dust towards us. The dust was maybe about 1.5 light seconds away from the stars.
Derek, thank you for this clear explanation!
Derek I love it when you get so excited about science.
When are you going to meet Professor Rana again? Our gravitational wave expert.
The gravitational wave are produced as the Neutron stars are spiralling each other . The first ones detected are the ones 1.7 seconds before collision. The light is created at that moment. Hence the 1.7 second delay. At least that is how I interpret the data. 😉
A message to Dr. Derek Mueller... I'm so happy men and women like you exist. I always tell young coworkers at my plant that if they choose not to go to college it does not mean you cannot continue to learn. Thank you.
I have so much respect for this channel. God bless you.
For studying the universe, Yes. But for exploring the universe, sadly not yet.
Humans have been astronomers for only about 400 years. Imagine what we will be able to detect when we've been at it for 4,000 years. The sad thing is none of us will be around to experience those discoveries. Rocket science..... pfffft. Baby stuff.
bangyahead1 born to late to discover the world born to early to discover the universe
Setting the foundations for future discovery of the universe isn't half bad, as things go. If you're interested in more than just parroting, feel free to pick up some books or read more about astronomy online.
Arent you a part of the universe? im pretty sure the universe will survive 4000 years, there is a long time until the "Big Crunch" in this particular dimension.
You are the universe and you are everything inside of it, you are that little tiny dot- that expanded into more space and divided into elements and soon will crunch together- back to big a new big bang
Forever.....ever....
Earthly beings have been observing the universe for hundreds of thousands of years, not 400...
400 years? Humans have been looking at the stars and the heavens for thousands of years. Agriculture is very important for people and knowing when to plant and harvest is very important to ancient civilizations. As a result, early astronomers created calendars to keep track of time and the seasons. The Gregorian calendar is based off the movement of the Earth around the sun, and the ancient Chinese developed their lunar calendar to keeps track of time using the moon's movement around Earth.
Thanks for such a good description of the event .
This video is at least 10 times better than any news article that I've read on the subject!
It always amazes me how anticlimactic astronomy is. The information of all of these unimaginably powerful and unbelievable objects and events is often encoded in the most apparently boring and mundane things, such as little points of light or tiny blips of sound.
Just goes to show that even the most seemingly insignificant things can reveal the most profound and meaningful things.
Better to keep the code and programs "simplistic" and functional than bombastic and clunky.
You should consider yourself lucky that we are far enough away from these events that they only register as tiny blips :D
That's just science in general
I see this as anything but anticlimate. Sure the signal strength is small, but what else do you expect from things so far away? I'm super excited by all this explosive outpouring of gravitational wave detections.
Astronomy _is_ anticlimactic. Know what stars look like with an expensive home telescope? Stars. Tiny points of light. Just like without any magnification. Mars looks like the eraser end of a pencil, and Venus is just white. Skygazers on those other planets are so lucky: Earth looks endlessly fascinating from space.
What's funny is we're on the verge of a new type of astronomy yet there is still people in the US out there believe the flat earth theory... SAD
Perfect length video for the subject!!
I really like to see that you love your job as much as you do, where would we be without people like you
i really hope all nations and humans can drop politics and military competition, regroup our resources and wise people to focus on the exploring the universe and other technology that make our life more meaningful

Einstein: I've just worked out with a pencil and a bit of paper that gravity can bend light and therefore we will one day detect gravitational waves
Rest of human race: Yeah we're gonna need about a century to let technology catch up with you.
Einstein: Drops mic, walks off stage.
Yeah Einstein did not invent gravitational waves and wasnt the only notable physicist in History. It's a shame you're not educated enough to know better.
@@are3287That's funny, being told I'm not educated by someone who clearly can't read, nor comprehend plain English. At no point in my missive did I suggest that Einstein invented anything.
You display Dunning Kruger tendencies, whereby you are simply too stupid to realise just how stupid you are.
Bye now. X
@@are3287 what part of what he said led you to believe he didnt know of other physicists? Einstein wasn't the grand solver of every problem but he was the one that worked out how gravitational waves would interact with light, which is what he was referencing. And while I disagree with the pretext of einstein being objectivly correct, and everything he came up with shouldn't be tested(that goes against every part of science). He is right in saying that einstein was able to work out how gravitational waves will interact with other particles and waves.
Actually, he did. He is the one who figured out and proposed the ideas of spacetime and General Relativity, and the idea of gravitational radiation and gravity waves is a direct result of that. He actually did first propose that they might exist, and did also give us the equations we use to predict and now detect them. In case you doubt, this is my current area of research. I study black hole mergers and use Einstein's equations to do so. It's a sub-topic of General Relativity. I use approximations to simulate these mergers, which are then converted into the Einstein equations, which are then used by a supercomputer to run more accurate simulations. That data is then used by scientists at LIGO and these other stations to compare against their detections to find signals that match.
You guys are so slow I saw that live 130 million years ago as I had front row tickets for this show.
dat guy who know what you did last night omg Rick ur the god
We all know it was you that caused it, no need to show off :p
What did I do last night?
Those neutron stars were so much better before they sold out and went mainstream.
Eating mcnuggets with the scechuwan sauce
Beautifully explained 😊
Great explanation, very exciting👍🏾
2:40 Watch the color and brightness change.
WHAT COLOR?
Red
I think it's funny, that there is no "proven" theory, that combines General Relativity and Quantum Mechanics, but we used Quantum Mechanics (Interference of Light) to measure effects of GR (Gravitational Waves).
There is no "proven" theory that combines general relativity and the germ theory of disease. That doesn't mean that they are mutually exclusive.
I didn't state that, but from our knowledge of the universe, we can't describe both at once, but still use one of them to detect the other ones consequences. That is just amazing!
Metagross31 Ahh ok. I get you. I agree, it is quite amazing.
QM is fine with curves in space-time. The part it has problems with is matter causing space-time to curve. So, it's all fine as long as you keep the GR event and the QM event a good distance apart, like 100 million light years.
Interferometers are explained with classical electromagnetism to be honest.
IM SO EXCITED ABOUT WHAT WE CAN LEARN FROM THIS AMAZING FINDING !!
Thank you for the Chinese caption , it is so amazing and exciting to learn the merging and collision of two neutron stars.
