  • 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.

    LIGO is funded by the NSF, and operated by Caltech and MIT, which conceived of LIGO and led the Initial and Advanced LIGO projects. Financial support for the Advanced LIGO project was led by the NSF with Germany (Max Planck Society), the U.K. (Science and Technology Facilities Council) and Australia (Australian Research Council) making significant commitments and contributions to the project.
    More than 1,200 scientists and some 100 institutions from around the world participate in the effort through the LIGO Scientific Collaboration, which includes the GEO Collaboration and the Australian collaboration OzGrav. Additional partners are listed at ligo.org/partners.php
    The Virgo collaboration consists of more than 280 physicists and engineers belonging to 20 different European research groups: six from Centre National de la Recherche Scientifique (CNRS) in France; eight from the Istituto Nazionale di Fisica Nucleare (INFN) in Italy; two in the Netherlands with Nikhef; the MTA Wigner RCP in Hungary; the POLGRAW group in Poland; Spain with the University of Valencia; and the European Gravitational Observatory, EGO, the laboratory hosting the Virgo detector near Pisa in Italy, funded by CNRS, INFN, and Nikhef.

    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.

      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.

      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

    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.

      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.

    • @BROODxBELEG
      @BROODxBELEG Před 6 lety +72

      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.

    • @TiagoTiagoT
      @TiagoTiagoT Před 6 lety +70

      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..

    • @ChenfengBao
      @ChenfengBao Před 6 lety +171

      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.

    • @nb8947
      @nb8947 Před 6 lety +40

      The visible light emitting component (the explosion) of the collision is preceded by the gravitational wave emitting component (the accelerating binary orbit)

    • @nmarbletoe8210
      @nmarbletoe8210 Před 6 lety +21

      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.

  • @stuartquark
    @stuartquark Před 6 lety +3

    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. 😉

      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.

    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.

      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.

    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.
