The discussion revolves around the nature of black holes, specifically questioning whether they have infinite mass and how this relates to the concept of infinite density. Participants explore theoretical implications, the nature of singularities, and the dynamics of the universe in relation to black holes.
Participants generally disagree on the implications of black holes having infinite mass and density, with multiple competing views presented regarding the nature of singularities and the dynamics of the universe.
The discussion includes assumptions about the nature of singularities and the interpretation of mathematical models in physics, which remain unresolved. The relationship between mass, volume, and density in the context of black holes is also a point of contention.
kapoor_kapoor said:Do the black holes have infinite mass?
Who says they do? In some sense, the mass would all be concentrated at ##r = 0##, but within the event horizon, the radial coordinate is time-like so it does not really correspond to a distance inside the black hole. Outside of ##r = 0##, the Schwarzschild black hole corresponds to a vacuum solution to the Einstein field equations.kapoor_kapoor said:If no then how can they have infinite density?
No. This is not how the Universe works.kapoor_kapoor said:Can we suppose that all the universe is orbiting a black hole (as heaviest masses bend the space time most) and loosing energy at some rate ?
No, and a quick google search would have given the same answer.kapoor_kapoor said:Do the black holes have infinite mass?
If there is a singularity in the center as general relativity predicts, it has zero volume but a finite mass.kapoor_kapoor said:If no then how can they have infinite density?
No we cannot, that does not make sense.kapoor_kapoor said:Can we suppose that all the universe is orbiting a black hole (as heaviest masses bend the space time most) and loosing energy at some rate ?
