If we accept the usual physics, the cosmos being much larger would have an acceleration at the speed of light by relativity if it were infinite in mass. While it might seem that the outward acceleration (mostly deceleration) would leave the cosmos open, the outward expansion of the cosmos astronomers see is not up to the higher speed of light to outdistance the escape velocity a relativistic cosmos of infinite mass would have. This implies the cosmos is finite in mass, and your roommate in college will always be where she wants in science savvy. If a higher speed of gravity is allowed, it holds the otherwise presumably infinite cosmos together explaining the giant cosmic regularitys found in 2007 since the measured strength of gravity is finite, even if gravity is much faster, here too the force is finite, and thus so is the mass. So nothing around us has infinite motion. If the cosmos is not a black hole and mass and energy aren't accelerating inward at the speed of light or faster, masses of more usual size than the larger cosmos with reduced mass (proven from the slower rate of fall of the mass) wouldn't be black holes either. If the cosmos is not at the speed of light, it's not infinite. If black holes are of lower mass yet, they are finite too. This was an idea of Einstein's about this. Infinities aren't science and like Occham's method, any quantity that's never actually measured is completely eliminated from the physics, at least till it's ever actually observed. The mass goes in and it may be invisible around the outer zone of rotation. I think this would be because the implosion of the field of massive bodies while finite would be faster than light but it would be connected to the rest of the cosmos by the faster than light speed of the field, and then be accelerated out faster than light by the jets to overbalance the implosion. Energy conservation says that mass is not destroyed inside a black hole, and faster than light would be the connection. The massive source of power is more black around the outside and more energized and light at the jets. The other type of black hole that would temporarily be black would be formed by the rarer event of two stars combining that would have almost exactly equal mass and spin so the field of the black hole created would have no spin and so no jets would be formed till more spin was added, the jets would eventully form with more infalling spin however. This would predict that there would be fewer large astronomical bodies that are black and not emitting radiation, the more massive bodies are emitting more light than any other.

While infinite black holes may be in error, I believe Einsteins Other "Great Mistakes" were like him and not in error and the other three were good physics too, and of worth for research more indepth and with more good turnaround value for reasons and with possible ways of proof I discuss on these links, About the Uncertainty Principle (my site about quantum codes). The Big Bang being stabilized by an opposite Cosmic Constant, (Double Vortex Cosmic Jet Cosmology) and Electrogravity. I think Einstein's 4 Great Mistakes May Be Of More Than Historic Worth.
