Talk about a mind-bender. A no beginning and no end approach is very Tralfamadorian...

If there's no change in time, I would assume that the universe is at a steady state, no? Which would then dictate that the change of entropy in the universe is undefined, since dt is zero. How does this theory not break the 2nd law of Thermodynamics. Or is it that t=infinity, in which case we're at the end process of...everything? This time the change of entropy would be zero for the entire universe, again breaking Thermodyamics. In this case, wouldn't the universe also have experienced heat death or some other awful end-game scenario?

This also has me thinking of a slightly related question or how the very first thing came to be. I guess this theory kind of resolves the whole infinite density conundrum of the Big Bang. Tangentially related, I'm infinitely curious as to how the very first thing came into existence. I mean the origin of the very first particle, be it a quark, higgs, anything.
