What if our universe was inside a black hole?

It's generally accepted by many that everything began with a big bang, and our laws of physics break down when we try to go beyond that. We also know when a star explodes that sometimes they create a black hole and our laws of physics, again, break down when it comes to black holes.

This universe is filled with energy and energy cannot be created or destroyed, only transformed into another form. A black hole consumes energy but that energy has to go somewhere.

Our universe is expanding and black holes continually get bigger the more they consume. Also nothing can escape a black hole and nothing is able to leave our universe.

This would also explain the concept of infinity. If inside every black hole is its own universe, and like ours has billions of galaxies, each with a black hole at the center which is in turn there own universes. And we're just inside a black hole that's at the center of a galaxy inside a universe that has billions of galaxies. that would mean that energy is infinite and that our creator was actually the death of a star in another universe.

It was would also explain why the laws of physics, that only apply to our universe, break down when it comes to black holes.

Thoughts?

To some extent you need to define what is a black hole.

If defined as something from which nothing can escape then as we cannot (it seems) escape the universe we are in one.

This has been around for many years, but it is just one way of viewing things. No more.

One problem with all this is that we are ignorant, after 100 years it seems to be assumed that we have the answers to everything (like this). Relativity is not yet 100 years old. Do you still talk about the force of gravity ??

We do not much at all, we know very, very little, and if you read around the vast majority are "What if.........?"

This os a What if,

I would say that the laws of physics did not break down at the big bang, they simply are not the mix that we are familair with now. The laws now predominate, back then other ones were likely dominent.

Inside a black hole the relationship between space and time becomes incoherent and there are vast tidal forces at work. We don't observe any of this in our universe other than where black holes are thought to exist.

However, there is a wonderful book by Lee Smolin (The Life of the Cosmos) in which the author's hypothesis elegantly addresses a number of fundamental cosmologogical problems, most notably the apparent need for fine tuning in order to have a star forming universe. He suggests that if stellar mass black holes seeded new universes with an imperfect 'memory' of their own parent universe then good star forming universes would select themselves into existence along Darwinian lines and become a probability rather than an improbability. Whether or not this really happens is anybody's guess but the thinking stikes me as quite beautiful. Well worth a read!

I have a few queries about your original proposition and the assumptions it makes.

I'm not sure what you mean by the statement "a black hole consumes energy"

Do all black holes continually get bigger? 

"Nothing can escape a black hole" what about Hawking radiation?

Taking in this case the laws of physics to be General Relativity (GR)  it predicts that the universe started at a singularity and that black holes also have singularities (there can also be bare singularities without an event horizon). These are point at which world lines start or finish. (Formally they not in space time at all.) While it is generally thought other physics will come into play before the singularity forms we don't have an agreed upon theory yet. Between the event horizon and the singularity GR is thought to hold in the same way we not think the laws of physics change as we reach the edge of the observable universe.

The conservation of energy is a consequence of time reversal symmetry and holds in inertial frames. However, it breaks down in curved space time (as does conservation of momentum with the loss of translational symmetry) as there is , in general, no time reversal symmetry. In addition in the standard LCDM model of the universe the dark energy density remains constant which requires the continual creation of energy, albeit at a very slow rate.

Some current models require some new universes to be continuously created like bubbles in boiling water. They are superficially more like white holes than black. It is not a model I favour as it leads to some 10^500 universes!

I prefer some of Lee Smolin's ideas about a Singular Universe undergoing various phase transitions and loop quantum gravity to String/M theory.
