What was the size of universe before Big Bang?
Indeterminate.
The Universe (as we know it) did not exist before the Big Bang and it was a singularity. (here the laws of physics are indeterminate). The Universe came into existence at Planck time as the symmetries were unraveled.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
