Paraphrasing here but-
The Ramban; Nahmanides, a 13th Century Great Jewish Rabbi, interpreted "tohu v' bohu" - the Void; emptiness; nothingness; formless; etc. - as The Absolute Nothingness that ever was. He posited that This Nothingness was an Absolute Point of Nothing in G-d's Creation. It was all of the Nothing that ever was and ever could be. Etcetera.
Which, in my humble opinion, pretty much describes the theoretical Black Hole that scientists postulate exploded into the Big Bang which, of course, happened when Hashem said "Let there be light!"
I do not know the figures but, I do know that scientists estimated that that there was a very long period (for us) of "time" after the Big Bang where all that existed would have been "Light" in the form of Energy.
Rabbi Isaac ben Samuel of Acre was a 14th Century kabbalist who estimated that, based on the Torah and the Zohar, the Universe was approximately 15 billion years old (give or take a couple billion)....
I don't look for the Torah to confirm science. But, I find it cute and interesting when science appears to confirm the Torah.
When the Big Bang was first proposed, those scientists were vilified as that would seem to indicate that there was a Beginning.... And, all good rational scientists of the time knew that could not be possible, mainly because the Torah said that there was, indeed, a Beginning....
