“How can you create a universe from nothing?

Well if you calculate the total matter of the universe it is positive. If you calculate the total energy of the universe it is negative because of gravity. Gravity has negative energy. When you add the two together what do you get? Zero, so it takes no energy to create a universe. Universes are for free. A universe is a free lunch.

And then you may say to yourself well that can’t be right because positive and negative charges don’t cancel out, therefore, how can the universe be made out of nothing. Well if you calculate the total amount of positive charge in the universe and calculate the total amount of negative charge in the universe and you add it up what do you get? Zero, the universe has zero charge.

Well what about spin? Galaxies spin, right? But they spin in all directions. If you add up all the spins of the galaxies what do you get? Zero, so in other words, the universe has zero spin, zero charge and zero matter energy content. In other words, the universe is for free.”
