If everything in the universe increased its size by 10 or 100 times except the universe itself, what would

happen?

Everything would come to everything else at a faster rate. Imagine two galaxies oming toward one another. If their masses increased then the gravitational attracion between them would thus increase resulting in them colliding in shorter time.
Hope this helps

I think you want to prove the existence of god this way.

Every action is a reaction of some previous action.
You look like human because your parents are human. Science doesn't understand most things but that doesn't mean god deliberately made it difficult. If god has done that then we could have never progressed in science which we human beings are good at

Example : every piece of technology u see around and as time progress more of hi-tech things arrives.

there is no evidence to support your belief in god(s)

the idea of "balance" in the universe is as mythical as that of religion.

It would turn into a giant Troll.
