Thanks for the clarification about recession speeds, Martin, it seems to make sense for me.
"If you want links to recent papers, please ask."
I don't know if I have enough understanding of theoretical science to read through peer- reviewed papers, but if you have links to some of them, than I might as well try.
If you guys are interested my theory, I guess that I will explain it, although keep in mind that it's a fairly basic, and I expect that it will have some massive holes in it. Here it goes:
In my theory, I'm accepting that m-theory (and therefore string theory) is correct. As I understand it, the membranes in m-theory have the possibility of being gigantic, and membranes/ other universes also have the possibility of having different physics from each other. If two membranes collided with something like our singularity (at the time, I was still thinking of a singularity as a physical object) in the center, it could produce a whole lot of energy, and the conflicting laws of physics from the membranes would make it so that our laws of physics were very badly distorted for a brief period of time, allowing for anomalies that would break general relativity. After this period, the physics of our universe became normalized, resulting in the general relativity that we have now. Feel free to debunk/ comment on it
