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.
I'm really not sure. This is by no means widely accepted. The dominant framework in cosmology is still that the Big Bang occurred, that dark energy is real, and that the universe increase in disorder (as long as you ignore the existence of intelligence). I just posted this because it will be interesting to see how the idea develops. In terms of origins of fundamental particles I think research has revealed adequately how the first atomic nuclei formed from the quark-gluon soup 10^-35 after the Big Bang. I think the biggest frontier at the moment is understanding the origin and separation of the forces (i.e., strong/weak nuclear forces, electromagnetism, and gravity). The answer to that mystery will be key for understanding the cause of the Big Bang.Tangentially related, I'm infinitely curious as to how the very first thing came into existence.

Oh yeah, this is clearly an alternative theory, and this one seems to resolve the issue with dark matter/dark energy, which is a big plus. Though those two issues I feel will come into play as we get a better understanding of what exactly gravity is. Hmm. Even further than that, down to the absolute base is what I question, how did the very first anything down to the smallest subdivision come to be. That's the question that freaks me out the most. Going from nothing to something.
