This means that it is only possible to obtain exact solutions for astrophysical situations for some very idealized conditions (such as spherical symmetry and a single body). The Einstein equations for general relativity are ten highly non-linear partial differential equations. Here’s one of the scientific papers on the process of determining the properties of the source of the signal, with three papers cited on which Jenn Seiler was an author: I also worked on developing the analytical formulas to determine those spins and masses from those signals. Those waveforms are then used again to determine where the signal came from, what it was (two black holes, a neutron star and a black hole, two neutron stars, etc), and the properties of the bodies that created the signal (spins, masses, separation, etc.). The detector matches the template banks against the incoming data to find real signals amidst the noise of the detector, while also doing searches for large burst signals (how this one was found). Those waveforms are used as templates in the detector pipeline. While I was in the field I ran super-computer simulations to make predictions about the gravitational wave signals that would be produced by binary black hole mergers. What role did Jenn, astrophysicist and Universe Sandbox ² developer, play in the discovery? This all of means that this detection means the beginning of a new kind of observational astronomy, as well as a better understanding of of of the fundamental forces of the universe, gravity.
This means that we can receive signals from very far away that we might not notice optically. Third, gravitational waves fall off in amplitude much more slowly than light.Second, this is an observation of the warping of space itself, meaning we can detect things that have mass but might not produce observable light, such as black holes, dense sources of dark matter (if such were to exist), cosmic string breaks, etc.This means we can see into regions of space that are blocked to optical observatories, such as inside dense clouds of dust, the centers of galaxies, behind large or close bodies. First, gravitational waves are practically impervious to matter in their path.Though gravity is the weakest force and gravitational waves are very hard to detect, they do have a few advantages over observations of photons.
In addition to this detection being the first direct proof that the predictions of general relativity that matter and energy warp space time are true, and some of the strongest evidence for the reality of black holes, this is also a new kind of astronomy. It is the start of a new age in astronomy. This will allow us to see the dark and the obscured parts of the universe: the early universe, centers of galaxies, things blocked by dust clouds, and so on, by listening for changes in space itself.
Now we can add listening to the fabric of space to our list of tools. Up until now we’ve used only photons (telescopes all along the electromagnetic spectrum) and sometimes neutrinos. It is also the first of many future observations that will look at the universe in a completely new way. It is not only confirmation of general relativity, though. It is the first direct confirmation of the prediction from Einstein’s General Relativity that matter and energy determine the motion of bodies by warping the fabric of spacetime itself, and in so doing, emanate ripples when massive bodies are accelerated through that space. Gravitational waves are a century-old (almost exactly) prediction now confirmed by a huge number of relentless, and brilliant people after many years of hard work. It is on par with the discovery of the Higgs Boson particle which provided the missing evidence for a prediction of the Standard Model of particle physics. What’s the significance of discovering gravitational waves? Researchers concluded the detected gravitational waves resulted from two black holes colliding.
