I believe the universe came from nothing.
Two waves cancle each other out to make the appearance of nothing. If the waves however are out of sync they no longer cancle each other and you'll have somthing from nothing. (Sort of) If energy is a wave form this could also be true for the entire universe. Since everything is basicly a wave anyway.
This does not violate the laws of conservation since the debt is repaid in Time. Universes poping in and out of existance would be my guess. A "pop" could seem like forever to us (Or a lifetime) but be an instant in the real scheme of things. A universe plus an anti universe would serve the laws of conservation as well.
+1 and -1 equal zero when added together. We see the possibility of how a universe can appear from the void when we look at either wave seperatly.
Slightly out of phase and Oula!
