One interpretation is that the contraction, creating a void, was followed by the light, or lightning, which created an incredibly small, but self replicating particle in the middle of the void. As it generated more and more copies of itself, they combined creating any number of complex things.
The purpose of doing this was to create a universe, that itself would “mirror” what was outside the void, so that God could find out if there was anything “not God”. Once it had achieved this purpose it would cease to exist and the void would collapse.
“It is the sound of my beloved knocking” – by means of Moses when he said: “Moses said: So said the Lord: At about midnight, I will emerge in the midst of Egypt” (Exodus 11:4). “Open for me” – Rabbi Yasa said: The Holy One blessed be He said to Israel: My children, open for Me one opening of repentance like the eye of the needle, and I will open for you openings that wagons and carriages enter through it.4. And Moses said, Thus said the Lord, About midnight will I go out into the midst of Egypt:

As long as the topic of the infinite light and the freedom from hard mind bondage is afoot, you two might wish to take a look back over at the "about midnight" in verse 4:
כַּחֲצֹת הַלַּיְלָה
You might already be aware that this is an ancient point of much commentary -- why this "about midnight" when David knew when it was exactly midnight. Not to divert, but just to note that there's a focus on this particular phrase for the timing of the Exodus.
Now what it says is "about the middle of the night", ergo midnight.
That's what I'm getting at -- "the night", and what's in the middle of it:
הלילה
"The night" is not just a palindrome, the "Y" is in the middle, the Pintele Yid. And it's flanked by lameds, so there's inherently more to the visual...
The purpose of doing this was to create a universe, that itself would “mirror” what was outside the void,..
I don't have an uploaded graphic handy, but perhaps you can visualize the word as a mirror on that yud point, flipping the second lamed and hei.
What happens it that
1) this forms the image of the Jewish heart with the Yid inside (well yeah, it's a Jewish heart). This page has the lamed-heart explained.
2) the traditional teaching is that the letter hei is formed by a yud + dalet. By way of the mirror, what is on each side of the lamed-heart in "the night" looks like this:
די💗יד
(I know, the dalet should be flipped too but there's no letter for that. I did the key thing, to flip the dalet - yud order on the second (mirrored) hei.
Now you can see the hands [יד] on each side, thumbs in, like cute little Ary the Lion whose face is heart-shaped, playing Moses:
*DAY*enu... דיי-נו. "Our Day" so to speak*, just like the letters roll out in either direction:
די💗יד
And all the firstborn in the land of Egypt shall die...
EGYPT up and died without a Jewish heart. "Died" דייד
It's all highly integrated.. an art *and* a science [מַדָּע], the science of "Y" [מַדּוּעַ] (Exo 3:3)
When you see a Y in the road, take it!
*You can find this דיי Day spelled right out in the last letters of the first three days of Creation, the same time and place as this mysterious first light of Creation under discussion.

Then we know this theory is wrong and anti-biblical.
God is omniscient. There is no "finding out" about anything.
