If gravity pulls matter so hard that light can't escape, it must be traveling at the speed of light somewhere else because of a difference in pressure, right?
Think of our universe as a balloon that's got a slow leak (black hole). It's known that our universe is expanding, so there must be something that's keeping matter in our balloon and inflating it but at the same time still allowing slow leaks to escape, right?
I think a hot air balloon may explain this. When heat is introduced, the balloon fills up with hot air and it expands, and in order to keep the balloon afloat, constant heat must be added.
Well, Stars are a constant source of heat, and although their heat may struggle to reach out of our solar system, trillions of stars could produce enough heat to make our universe expand and compensate for the leak. So if what-ever is outside of our universe, must be either colder or have less matter(diffusion).
Can someone chime in on this?
