Was the Universe a point prior to the Big Bang ?

Was the Universe a point prior to the Big Bang ? * There were no histories prior to the Big Bang * This implies that there was no time evolution of space prior to the Big Bang * This implies that the Universe was static prior to the Big Bang * This impli

Answers:

Where is the rust before you oxidize the iron?

Theoretical and quantum mechanics physics make NO assumptions, like you are, that the Universe existed as ANYTHING, except possibly ANOTHER universe, BEFORE the Big Bang.

The universe MIGHT exist because of a random quantum fluctuation in the quantum foam or subspace.. Physicists are not assuming that the Universe existed at or AS ANYTHING BEFORE the Big Bang.

Yes, the geometry resolves to a point, but the point does NOT HAVE to exist BEFORE the Big Bang.

I don't understand: If you believe you know the answer already, (as you obviously do), why bother to pretend to ask the question?

<QUOTE> Was the Universe a point prior to the Big Bang ? </QUOTE>

No, for the same reason that there is nothing smaller than a point. We just don't know if the question even makes sense. It's like asking what's north of the North Pole.

No.
For one thing, we do not know what the phrase "prior to" means in this context.

There is no big bang, in the Big Bang theory. The "bang" is the expansion of space itself, and that is still going on.
There is, however, a moment called the Planck Time, which is the earliest moment we understand using the Big Bang theory.

At the Planck Time, the energy density would have been so high that we don't know how things work at higher levels ("before"). Worst, we don't even know how time itself could flow at that level of density.

This does not mean time did not flow... it simply means "we don't understand".
That makes it difficult to use the work "before" at that moment.

The Observable Universe would have been very small at that moment (but it would still have non-zero size in all three dimensions).
Now, for the big "if":

IF the universe (the whole thing, not just the Observable part) is infinite now, then it was already infinite at the Planck Time.

"Before" that? we cannot know. There are roughly half-a-dozen scientifically sound ideas as to what it COULD have been, and only one of them has it being a "zero dimension" point. Since none of the ideas can be tested (yet), picking any one of the ideas is, for now, just guessing.

>> This is consistent with a zero dimensional structure.
It's also consistent with a non-zero dimension structure, even with infinite size.
