Our Universe in a Black Hole, Dark Matter, and Dark Energy: A Beginner's Hypothesis
I'm not an astronomer, just an endlessly curious fan. Some (or many) of my ideas may be incorrect. If so, don't hesitate to point out any misconceptions I have. It's much appreciated .
There is a notion that our universe could be inside a black hole, which got me thinking...
Prior to the Big Bang, there was the initial singularity, a gravitational singularity of infinite density thought to have contained all of the mass and spacetime of the Universe before quantum fluctuations caused it to rapidly explode in the Big Bang.
This initial singularity is quite similar (the exact same, for all I know) to what we would find at the center of a black hole, where general relativity describes a region where the spacetime curvature becomes infinite. Or in other words, a gravitational singularity.
Dark energy is a hypothetical form of energy that permeates all of space and tends to accelerate the expansion of the universe.
Dark matter is a type of matter hypothesized to account for a large part of the total mass in the universe. Dark matter cannot be seen directly with telescopes; evidently it neither emits nor absorbs light or other electromagnetic radiation at any significant level.
Given these facts, could it be that the singularity that was our Universe was once the singularity in a black hole? Could some specific occurence in a Universe (a gamma ray burst, maybe?) cause the singularity in a black hole to undergo it's own "big bang"?
When a black hole "swallows" an object, that object is put into the gravitational singularity at the black hole's center. But if the vast majority of mass in our universe is mostly empty space, then where does the space go when the object joins the singularity...?
Is it possible that after the Big Bang occured, any matter that our "mother black hole" swallows is put into our universe as dark matter, while the space that our mother swallows is thrown in as dark energy?
And wouldn't it make sense that the expanding nature of our Universe is due to swallowed space constantly being thrown in by whatever black hole is eating it? After all, if space is endlessly put into an area that contains masses then those masses must be pushed apart, creating an effect identical to how our universe expands.
Lastly, my ideas in short:
Gamma ray burst (or another occurence in the Universe) causes the singularity in a black hole to experience a "big bang", starting the beginning of a new Universe inside that black hole. We'll call it Universe2.
Any subsequent matter swallowed by the black hole is put into Universe2 as dark matter, causing the inconsistencies in the Universe that we attribute to dark matter (stars and galaxies moving faster than expected, etc.).
Any subsequent space swallowed by the black hole is put into Universe2 as dark energy, causing the ever-so-puzzling expansion of the Universe.
Thank you all! There's quite a bit more, but I'll stop there. Any input is highly encouraged, I'm quite fascinated by this stuff!
