universe sandbox is terrible at simulating collisions, what those galaxy collision videos use to make it more realistic are particles the galaxy is made of, millions of them and you didnt even bother to change the particles of the galaxies in universe sandbox you can actually do that if you select the galaxies for example my profile picture uses a program called spacesim to compute planet collisions with particles to make planets deformable
@@punamaass9802 my exams are starting tomorrow, so I won't be able to make any videos for a while. In the meantime, feel free to share that idea with @stellaf01-I'm sure she'll do a great job with it! :')
General Relativity predicts dilation wherever there is an astronomical quantity of mass, not singularities. Dilation explains dark matter. In the 1939 journal "Annals of Mathematics" Einstein 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 fundamental phenomenon of dilation. Mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon our high school teachers were talking about when they said "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 occurs 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.
Hey, I didn't skip that. I showed your idea and Stella's. You both only commented your ideas, and for this video, Stella's idea was shown. In the next video, I will use your idea!
