Timelessness

[Time Traveler]

Ah, I think I get it. I've posted about the low entropy point with futures in both directions before, it's very appealing. What seems to break time symmetry (apart from the tiny CP violation in weak interactions which is not a drastic breaking) is the wave function collapse of the usual copenhagen interpretation of quantum mechanics. It only goes one way apparently. Is Stenger says something interesting about that, I have to read it.

I think Stenger's books are probably more targeted to laymen, though he does include blocks of physics equations which will certainly mean a lot more to a physicist like you than me. I think he wrote a number of white papers and other technical publications which would probably be more up you alley. In The Fallacy of Fine-Tuning, Stenger gives a very superficial explanation of the "biverse" model, so you may have better luck exploring Carroll, et al. who originally published the hypothesis.

My question for you would be: At the beginning of our universe there was a slight disproportionality of what we now consider matter over antimatter (about 1 part per billion difference if I remember correctly.) Is it possible both matter and antimatter were indeed produced in equal quantities and the antimatter resides on the other side of the "biverse" Carroll and other proponents imagine? Because my limited understanding is that antimatter can be looked at like matter, simply flowing in the opposite time direction. In other words, if Carroll (and others) biverse model is correct, would we expect to find it populated with antimatter, or matter?

The "B" theory of time really blows me away. I have a hard time wrapping my head around all points of time existing simultaneously. It's never a good bet to go against Einstein but is that really what is meant in relativity when it says all observers viewpoints are equally valid? Must all of time simultaneously exist like Brian Green's slices on a loaf of bread analogy to satisfy that tenant of relativity?

That's my understanding. Of course, Relativity breaks down at a quantum level, which gives theorists some wiggle room in exploring certain aspects of how time works on micro-levels. But read about the twin paradox, time dilation, length contraction, etc., and if the reality of those things don't hurt your head, nothing will.
