I do not have any mathematical proof of this being possible, but am hoping to include equations soon. For now, it is purely conceptual. According to the Steinhardt-turok model, our universe is on a 3-brane located next to another 3-brane. I will assume this is the case. I am also presuming...

I've actually been looking into the metastability event myself, but I don't think anyone could truly know. Any experimental evidence to suggest it exists would end the universe in the blink of an eye =P

Well plenty of work has been done on M-theory and we have no direct evidence of this, either. According to known knowledge on M-theory, does this work? I guess this is a better question.

I'm not sure whether this belongs in this topic or Beyond the Standard Model. I was reading through various articles and threads on this site when I had an epiphany, and now I am curious to see if it could work. The biggest influence on the fate of the universe is its entropy. Because...

Yes, I was hoping to find more information regarding any non-eternal models, any that do not cycle on forever. Also, if a reason for why the model or theory or whatever it may be is not more widely regarded.

I am doing a project in school and am looking up different cosmological models to research. I have found Steinhardt Turok Model, Kaluza Klein. I know these are not the best models, so I was wondering if there are any more specific models that I can look into.

From what I have gathered, M-theory states that there are 11 dimensions. We live in 4 of these dimensions, and I believe the common understanding is that the 7 other dimensions are incredibly small. At the time of the Big Bang, these 3 dimensions expanded along with the universe while the...

Wait, so if the other dimensions are compacted, but everywhere, what is the difference between them and the other dimensions which are also located everywhere?

From what I have gathered, M-theory states that there are 11 dimensions. We live in 3 of these dimensions(unless time is considered its own dimension), and I believe the common understanding is that these other 8 dimensions are incredibly small. At the time of the Big Bang, these 3 dimensions...

Ok thank you. Does it also explain exactly where all of this matter and energy AND dimensions came from?

These responses are helpful, but I can't quite understand what it all means yet. Is there a universal understanding on this topic, or has it not been studied enough in order to have a solution?

Oh ok. But does dark energy affect this, seeing as how it cancels the effect of gravity in the universe? I know dark energy is causing the acceleration of the universe, but is it considered antigravity?

Yes, but is the amount of energy needed in order for the Big Bang to occur calculated already? I read somewhere that it was a rather minute amount as compared to the energy the Big Bang created.

I have recently been studying cosmology in my free time, but I came across something that strikes me as rather odd. From what I know, at the time of the Big Bang, there was an even amount of matter as there was antimatter. There was also a superpartner for every particle. This would cause the...
