Simulating interacting binary stars with Octo-Tiger and HPX
If you work with the postulates of Einstein's theory of relativity. And if we apply new technologies for this, using the experience of Michelson Morley, we will see how quantum gravity works.
Good talk. Thank you for sharing. 😀 I have a few questions. The modeling with neutrinos. Is that just outside the event horizon? Did you find boundaries/cutoff for particle types and acreation ring falling in? Was part of your modeling creating a fermi bubble or similarity? Glad to see you go over R process. Have you tried using the same valley of stability for matter and use it to calculate the valley of stability for antimatter? Does your modeling get to neutrinos condensing to a short lived fluidic when falling into a black hole and from the infalling acreation disk, or tidal event? Or QCD mixed to prefered state or such?
In 50 years or so we will have formulas for the core structure in neutron stars, whereas at this time the core is a mystery. Since the natural forces of the core are beyond our current understanding. Since the star does not collapse but retains its structure and will provide it's history in our universe. Even she is at this time attempting to understand the core, just like Hans Bethe did for our understanding the core of fusion temperature and pressure we humans will slowly gain an understanding of neutron stars not available in the lab but will slowly show how it works with high energy particle accelerators.
finally some update which is not classified ! i loved it ! and enjoyed. can't wait to see the solution about when the warp field collape challege which se state what happened inside the space ship.
The fundamental phenomenon of dilation explains dark matter. Mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. A time dilation graph illustrates the same phenomenon, it's not just time that gets dilated. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers. The mass at the center of our own galaxy is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. In other words that mass is all around us. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has been confirmed in 6 very low mass galaxies including NGC 1052-DF2 and DF4 to have no dark matter, in other words they have normal rotation rates. All binary stars have normal rotation rates for the same reason.
Most people don't know that Einstein said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was referring to the phenomenon of dilation. Mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. A time dilation graph illustrates the same phenomenon, it's not just time that gets dilated. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers. The mass at the center of our own galaxy is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. In other words that mass is all around us. This is the explanation for dark matter/galaxy rotation curves. The "missing mass" is dilated mass.
Ovchinnikov Zhavlan. Kazakhstan. Almaty Hello. Let's look at the Universe through the “lantern for gravitational quanta”? And we will measure the Universe with gravitational quanta (in digital format)?! With the help of the “HYBRID gyroscope” you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,... I am writing to you with a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core photonic-substituted vacuum zone or (NANF)” where - the light travels 250000 (750000) meters in each arm, while it does not exceed the parameters 84/84/84 cm, and the weight is 24 kg. Manufacturers of “Fiber Optic Gyroscopes” can produce HYBRID gyroscopes for educational and practical use in schools and higher education institutions. Einstein dreamed of measuring the speed of a train, an airplane - through the Michelson-Morley experiment of 1881/2024, and only then would the experiment be more than 70% complete. This can be done using a fiber optic HYBRID gyroscope. Based on the completion of more than 70% of Michelson's experiment, the following postulates can be proven: Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum. (We are not looking for ether, we will see the work of gravitational quanta) The result is a «theory of everything» in a simple teaching device and a new tape measure for measuring the universe.

hello friend
Thanks for this video...I will be part of Einstein Toolkit development team
how to give input for any metric, say Schwarzschild metric?
can u guys make a video on how to install and run einstein toolkit in cpp
okk no worries JAI SHRI RAM
only 2 comments
Neat!
I am a beginner on the numerical relativity.I like!
Thank you very much!!!
Mulțumesc mult!!!
Sorry! Question : Example(2) BSSN Hamoltonian constraint ..... Here WHAT IS BSSN?
Will there be windows workunits?
Analytic (differentiable) is dual to synthetic (integrable). Syntropy (convergence) is dual to entropy (divergence) -- the 4th law of thermodynamics!
Thanks
Thanks! It looks like great work!
Great
