Does this video make sense?
The Simple Math for a Universe from Nothing
I mean, can I really explain a "universe from nothing" is this simple manner?

See Total energy of the Universe. This is essentially a duplicate of your question. The video is pointless because you can't describe the universe without general relativity. – John Rennie Dec 11 '14 at 07:20

"Nothing" in science (physics) means the quantum vacuum and not the "absence of anything", as far as I know. – Madde Anerson Dec 11 '14 at 06:39

I'm closing this as a duplicate, but beyond that it's not even asking anything as currently written. Questions need to be self-contained so that you don't need external resources to understand what they're asking. – David Z Dec 11 '14 at 09:29

It is metaphysics, instead of God creating the universe , it has Nature creating the universe, and hand waves mathematical possibilities to justify this metaphysical premise.
Some inconsistency in the end when using Newtons gravitational equation and assuming the masses zero, he says that the distance is zero too, but the distance between two nonexistent masses is undefined, not zero.
In a sense also it is a fall back to the platonic ideal of philosophy , when seen as "mathematics exists and forces form" .
Avoiding the word "creation" gets closer to physics theories which at the moment are open ended as to the beginning of our universe, i.e. there are various proposals which you may study if you continue in physics. As the beginning of the universe requires a unification of forces and quantization of gravity this is a research frontier. There may be much more interesting mathematics after all, than simple equations. They might tell us how the "choice" was made, so more interesting metaphysics :).
