Quote:No one knows for sure how the universe really started. One hypothesis is that there's no such thing as absolute nothingness, and that universe began from quantum vacuum, which is as close to absolute nothingness as it currently seems possible to get. There are numerous other possibilities that are mathematically sound and agree with what is already known, but we need more evidence to say which one is most likely to be correct with some certainty.
I suspect that the number of mathematically sound theories that are consistent with what is already known is unbounded--I think you could arbitrarily extend a consistent theory by merely appending mathematically-consistent objects (the consistency could be achieved through appropriately defining the object you're adding), similar to a field extension.
