Hey Vsauce, Michael here.

The animation universe needs physics and math, just like every other multiverse does.

Or does it?..

—–
Here i am to blabber nonsensical shit on this site to make up for this universe i’ve made.

Anyways, 1 + 1 = 2
1 – 1 = 0
1 x 1 = 1, its all the same as the real universe.

Galaxy forms from interstellar gas, nebulae, clouds, black holes, etc. = false

Stars collapse into a white dwarf or black hole after supernova? = false.

Not the same.

Lets explain wh at happens to stars after death first.

Well, it ejacuates byte matter and fuel and whatever else its composed of, therefore it its just a ball of gas with no light floating through space, and will eventually become balls of byte matter that are not even byte matter anymore so at that point they’re a failed black hole.

How do galaxies form?

gas floating in space that form in random shapes by unknown gravity. <— a.k.a collision is too lazy to write it so he'll do it later.

If you have questions, ask them in the comments about this universe.
