Universe = size of grapefruit?

If the universe did not come from a singular point, then that brings up questions of causality; how could everything come from absolutely nothing? But is easier to think that the universe came from nothing when if it began from a singularity, because a singularity can be considered nothing, since there is no dimension to it.

This is certainly not the big bang theory... do you have anything to support this? It seems like nonsense!

Light travel time is not a certainty either. You must accept that GR and redshift correlation to distance is correct. These appear to be good bets, but, not proven - nor will they ever be. BB is basically an extrapolation of GR. Since GR is not absolutely proven, any extrapolation is even more uncertain. Most scientists recoil from any therory that predicts infinities in nature. It indicates the theory is unreliable at that level.

If the universe always existed, then that's the same thing as saying that there's no tracibility to its ultimate cause. It's a denial of cause and effect. It's the same as saying that the universe is illogical and not reasonable. If the universe started from a finite size, then this is the same problem; it only differs in a matter of scale. You're still saying that some finite size universe always existed. Since you cannot trace it back to a time before that, you're saying it always was. So the only way cause and effect remain tracible from the beginning of the universe is if it started from a single point. This is not to say that some things have infinite value at the single point, only that it must have started from a single point.

I'm not debating it, I'm asking for a source... I don't think it is appreciated in this forum to set out and defend personal theories.
