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.

The video didn't explain the absurd sensitivity of the instrument required to detect gravitational waves. That's what caused people to be skeptical, not the idea of detecting gravitational waves. How do you rule out that the vibrations are of Earthly origin which are much much much more probable?

The Claim is quite simply incorrect ! As less than 0.5% of mainstream Cosmological scientists availed themselves of an Electrical Engineering degree or better, they are in the words of an Astro Electrical Physicist "Not qualified to look at the Universe, so of course they cannot identify correctly what they are looking at".

Danish physicists claim to cast doubt on detection of gravitational waves *The creation of an illusion* Understanding by analogy; The cookie dough is represented by the noise picked up by the instrument (LIGO) in order to create a cookie (the chirp) you would need a mold (the filter) and impress the cookie cutter (mold or filter ) into the mass of dough (noise ) in order to form the cookie, the expected signal the chirp. So you see, the signal, the so called *gravitational chirp (the cookie) is a creation of the process (*Convolution) a mathematical artifact and it doesn’t stand alone.* Without the cookie cutter (the filter) you have no cookie (Chirp signal)! *Convolution; is a mathematical operation on two functions (f and g) that produces a third function expressing how the shape of one is modified by the other. The term convolution refers to both the result function and to the process of computing it. It is defined as the integral of the product of the two functions after one is reversed and shifted.

183 MILLION years ago 2 dinosaurs on opposite sides of the largest landmass took a sh!t in the local river...simultaneously this caused a gravity wave in the water that traveled many miles and eventually collided creating a Supermassive 'hydrostatic ripple merger' that scientists have just detected with LIEgo and its theoretically beyond questionable irrefutable absolute fact and they know which 2 dinosaurs were responsible. Simple mathematical equation.

*The quantum Microscope LIGO* It is appalling the lack of self assessment in the scientific community, relating to this LIGO chirp. Possibilities; Microscope *LIGO device is actually a seismic instrument,* for detecting and measuring activity in the quantum environment, what is referred to as the quantum foam or ether. What is this “foam “ ? Well, John Wheeler derived the concept of the “quantum foam” in 1955. It is also referred to as spacetime foam and bears a superficial resemblance to the old concept of the ether (or Aether). So inadvertently these scientists have entered the realm of the Quantum environment, and are listening into a new phenomenon called Quantum foam which physicists describe to be a place of violent activity of the quantum world. ...the chirp is nothing more than the pops and crackles of this quantum environment and are not related to black holes.

Explosions will never yield something greater than what it started with. If mass is energy and explosions takes place which implies an expenditure of energy or a lost of mass which will produce less gravity (less gravitational energy) specially , when considering a sphere gravitational energy is concentrated on the surface. In insisting that a explosions creates something of greater gravitational energy is to violate the laws of nature (Conservation of energy) in other words, you’re claiming perpetual machine. This presentation is total hogwash

"There can be no doubt..."? Science consists of two wings, The theoretical and the pragmatical. If this discovery can be put to use, then fair play. So far, only Kepler's laws, Doppler Shift, Boyle's Law, and a few others, have worked out for practical purposes in astronomy. All the rest, like Time and Space are conjectural. BTW, Maths is not physics: maths is an abstraction of the world, it doesn't actually exist, whereas physics is real. We landed a man on the moon, and took high-quality photos of Pluto, using what we know for sure in physics. Theoretical physics, like black holes and space-time and the Big Bang, are speculations, and never actually observed. Computer models and out-of-this-world maths, and the backing of half-wit professors pleading with the bursary for a hand-out, is not science, it is buffoonery. Lets get real: can you cure cancer? Or don't you give a damn about the real world? Gravity waves? Is it even a wave? A quantum particle, maybe. Or even something else? More research is needed, more funding, bigger computers, better staff, more money...

If you put a black hole in between sun and earth, and you make the sun disappear. The gravitational wave will travel through black hole and reach earth in speed of light, but the sun light will be distorted by the black hole and circulate black hole several times before it leaves black hole orbit and went towards earth. which means the gravity of sun will disappear earlier than sun light. Also, if you put a large body of water or cosmic dust in-between sun and earth, light will slow down, but gravitational wave won't slow down.

*Gravitational wave and its problems, explained* Lovely, beware of one hand clapping. Now for the bad news, In reference to this signal( gravitational wave) here is something to consider LIGO False positive; the problem is that the methods used to Extract the signal From a sea of noise and the interpretation of such a signal signal. The signal amplitude is smaller then a atomic nuclei a it must be filtered out from a sea of noise, the methods used is highly dubious, because the investigator introduces a predetermined template comparator that may introduce a bias in these extractions (observations). Furthermore, the filtering processing requires a inordinate amount of data processor or data comparison in Searching for the predetermined signature of a chirps, which starts with a low and moves to a higher frequency, may also be the characteristics of many other natural phenomena, not related to gravity. There is also another problem, interpretation of the source, at is, to associate the Signal (chirps) with a Specific cosmic events (Gamma burst, x-ray emissions). There are three natural relationships: similarity, contiguity and cause and effect. Of these, the causes and effects it is the most problematic where the narrative does not have a connecting principle, but instead it is artificially juxtaposed by the mind and not real. In other words, how many of these events could be associated artificially and are not real. How many of these events occur in the Universe and are accidentally and wrongly associated. This is a problem that has not been answered beyond a shadow of a doubt. *This is a prediction; they will find these type of phenomena (chirps) are very common in the environment and are not related to black holes. It Is going to be the biggest debacle in Scientific history! Similar to the epicycles of the past.*

*Singularity and infinities* Infinities and inconsistent reasoning. Here is an argument; in general relativity the equation called the Lorenz transform is used to calculate the limits of mass acceleration which basically is one over square root of 1- v/c where v= velocity of the moving object and c= Universal speed of light , note when v approaches the velocity of light the ratio v/c will equals 1 therefore the divisor becomes Zero, that is, you are dividing by zero (infinity is the result), which According to the theory of relativity means matter cannot be accelerated to the speed of light, or matter can not Exceed the speed of light, it is prohibited, because you cannot divide by zero (which would yield infinities). And this is perfectly reasonable argument, because this has been confirmed by particles accelerators, incidentally the discipline of particle physics which also interprets infinities results as a Indicator of an incorrect theory. But in black hole Schwarzschild equation which states the radius of the Events horizon ~ 1/(r x c^2) where r is the radius of the singularity which equals zero when black hole status is reached, we have a mathematical scenario which we are Again dividing by zero. And yet this is interpreted as acceptable, this infinity would allows matter to be compressed to infinity, a preposterous interpretation. Yet the opposite Interpretation is rendered when general relativity and in particle physics are Involved. Only in Astrophysics is these infinity results are Considered to be valid , and nowhere else, this is inconsistent Reasoning. why is this excepted?

Well here is a dose of Veritasium; the concept of the black hole or neutron stars violates universal law, as follows Explosions will never yield something greater than what it started with. If mass is energy and explosions takes place which implies an expenditure of energy or a lost of mass which will produce less gravity (less gravitational energy) specially , when considering a sphere gravitational energy (newton Mechanics’) is concentrated on the surface. In insisting that a explosions creates something of greater gravitational energy is to violate the laws of nature (Conservation of energy) in other words, you’re claiming perpetual machine.

I hate to bust your bubble, but In reference to this signal (so called gravitational wave), Has a flaw which needs to be addressed and that is LIGO False positive Issue, the problem is the methods used to Extract the signal from the sea of noise (which has a amplitude smaller than the atomic nuclei), the researchers use a predetermined template scheme that Introduces a bias in these observations which would lead to a false positive signal. Also the expected signal called the chirp which Exhibits a low to a higher frequency signature may be due to many other natural phenomena.

This is a problem that has not been answered beyond a shadow of a doubt. This is a prediction; they will find that these types of phenomena is Very common and are not related to black holes or neutron stars, but are part of background local noise. It Is going to be the biggest debacle in Scientific history! Similar to the epicycles of the past.

In the graph against light and gravitational waves i saw the gravitational wave is detected first and then the light. So can we say that gravitational waves travel faster than light. And we broke the rule that nothing can travel faster than light.

@Lünkel Thank you for that explanation. I have one more doubt is there anything in the universe that can slow down the gravitational wave
Lünkel År sedan
No, it doesn't. Nothing can travel faster than the speed of light in a vacuum. However, space is not a perfect vacuum and light slows down when travelling through a medium. So the light was slowed down by the interstellar medium, while gravitational waves are not. Also, the light is released in the moment of the neutron stars hitting eachother, while the gravitational waves are strongest moments before that.

That implies there'll be a lot less tools to understand our universe. No Hubble, Chandra, JamesWebb etc...

This guy is too enthusiastic. It is estimated by astronomers that if a detector covered the whole sky, all of the time, we'd detect about 2 GRBs per day on average, so one event correlation would still be accidental coincidence and may not be real, more would be is needed to affirm the conclusions, there is plenty of room to be wrong. How many flashes do you think there are in our sky in one day? Nevertheless , it's Amazing. How out of one chirp you can get such a convoluted story...Well, I guess, if they don't , they will run out grant money. I predict this is going to be the debacle of the century.

Newton's Law; for every action there's a opposite reaction, is still held Supreme and gives the universe stability. The Pauli exclusion principle keeps neutrons from collapsing any further, and according to this hack theory, it is the force of gravity which keeps this bogus neutron star intact. He also forgot the Heisenberg principal which is a corollary principle, that states; the more the confinement of matter the greater the outward momentum, there by countering further increase in density. This momentum is vectored against gravitational force preventing black hole or neutron star from forming.But let us not mention that, it will spoil everything.

"No more doubt..." LIGO GW required several trigger times to reveal any pattern to their arrival times and correlations between their energy, distance, masses; the incompatibility of LIGO objects as a class with all other known BHs and, now, neutron stars should be considered as evidence of foreground effects, poor signal processing, bad statistical modeling, or an entirely different class of transients than BHs and NSs. We know from responses to the Creswell 2017 paper by LIGO, and further work by Akhila Raman, that poor signal processing and bad statistical models are accepted by LIGO and biased peer reviewers as standard and sufficient to approach false alarm rates and precision error so extremely small.

LIGO detected discrete interplanetary-Earth feedbacks known as magnetospheric sawtooth boundary/particle injection events, which are day-minute correlated to activity of Earth-facing coronal holes, sunspot number, TGFs, substorms, and other periodic space weather. GOES and ACE record these fluctuations, with superimposed 5-minute pulsed globally-coherent CG lightning discharges and ground magnetometer data, coincident with phase-locked quasiperiodic LIGO "noise." Major thunderstorms were active in the line-of-sight, displaying this burst behavior, of LIGO detectors during GW triggers. Several unbiased analyses on LIGO data that I have conducted are available:

So, the event was located at 130 million light years away and the gama rays reached us just 1.7 sec after the gravitational waves produced. 1.7 sec difference in 130 million years is a very very...very small difference. It looks like the speed of gravity is the same than the speed of light after all.

Since the speed of light is not infinite, light takes time to reach us. Gravitational waves also happen to travel at the speed of light. As a result, something that happened 130 million light years away would take 130 million years for it's light and gravitational waves to reach us. In other words, these findings describe something that happened 130 million years ago.
