Considering our galaxy alone is 200,000 lightyears across, there's a good chance that if this started on the opposite side of our galaxy genetic drift in the human species would destroy humanity as we know it before this became a concern.  If it happenened in any galaxy outside of our Local Group (which is 99.999999999999999% of them) then the sun's stellar evolution would be a far more pressing concern to us.  In fact, it's entirely possible protonic decay may become a bigger concern, especially considering that universal expansion wouldn't be halted by this.  The universe is BIG ya'll.

I have often thought of putting bogus math equations into paper submissions, just to make some poor grad student spend the time to actually disprove the math...not just minor ones, either...like the WHOLE thing would be full of equations that had absolutely no bearing on the topic of submission...

Not possible to be occurring now within the observable universe.  A certain percentage of local particles are connected through quantum entanglement with other particles and it stands to reason that some are connected with particles billions of light years distant. I'm pretty sure the entangled local particle would exhibit some change state if its sister particle underwent one.

Yeah, I hate to bust the article writer's bubble, but theoretical physics is just a place for ideas -- without testable, falsifiable evidence, these ideas are just peculiarities in math that can be debated, but which amount to little more than educated speculation.

What's more, this isn't even a new idea. The only thing new here is that these guys have figured out a way to lend more credibility to the idea using a new approach in the math.

OneFretAway: "The basis of the theory is that sooner or later a radical shift in the forces of the universe will cause every particle in it to become extremely heavy.   Everything - every grain of sand, every planet and every galaxy - will become billions of times heavier than it is now."

... a process that may have already begun with Subby's Mom.

Every particle has a symmetrical partner that is traveling backwards in time and is also reversed in some other basic ways. From their perspective, we, and everything in our universe, are those symmetrical partner particles. The big bang was just one end of a cycle. At the other end is a big bang for those particles. But nothing actually ends.

There's nothing to enlighten. It's just word salad by somebody who once heard the words "quantum" and "entangled" but has literally no idea how to use them correctly in a sentence. The last sentence in particular is a dead giveaway of somebody who doesn't understand what entanglement means.

If he was within six leagues of saying something coherent I'd take a crack at clarifying. But the only "clarification" to be made here is to throw the whole thing out and say something completely different. So why bother?

It is, to quote the great Wolfgang Pauli, "not even wrong".

dangelder: Every particle has a symmetrical partner that is traveling backwards in time and is also reversed in some other basic ways. From their perspective, we, and everything in our universe, are those symmetrical partner particles.


Not really, no. Time reversal is an interesting mathematical way to interpret the symmetry of the Dirac equation for the electron, but it doesn't really have any meaningful physical interpretation. In particular, cause and effect only ever appears to operate in the forward direction, so this supposed backward traveling particle doesn't carry any information backwards, which makes any interpretation of the positron as a time-reversed electron of limited physical interest. (The same goes for the retarded waves predicted by the symmetry of Maxwell's equations.)

There are also other more detailed problems, such as time reversal not being a perfect symmetry; and the huge asymmetry between matter and anti-matter. There are many more electrons than their are positrons. So it really doesn't work to imagine the presence of a time-reversed "mirror universe" rushing past us in the opposite direction.

The big bang was just one end of a cycle. At the other end is a big bang for those particles. But nothing actually ends.

It's an open question as to whether our universe is open or closed. If it's open, there's no Big Bang for time-reversed particles under any interpretation. The apparent presence of Dark Energy suggests it's open, which means it will end in a Big Rip, and after that... no theory we have predicts what would happen after that.

Even if the universe is closed, it's far from clear what would happen in the Big Crunch. Some theorists have even suggested that one or more of the arrows of time would reverse at the mid-point as the universe begins to contract. And we certainly have no coherent theory of what happens at a Big Crunch -- whether there is a "bounce" and another cycle afterwards is purely speculative. However, there's some good work that suggests that, if the universe is indeed cyclic, (a) each cycle starts with higher entropy than the previous one, which means that the whole thing will eventually peter out into a bland, maximally entropic soup; and (b) bounces cannot have extended infinitely into the past (because if they had, we'd already be in that maximally entropic state, which clearly we aren't). Of course, this work too is speculative because we don't really know what happens when the universe is close to a singularity, but there are good reasons to believe that the principle here is relatively immune to the precise details of what happens at the pinch point between cycles.

TL; DR: when it comes to cosmology, science fictiony hand waving is easy; actual physics is hard.

There's speculation that's within the realm of possibility; there's speculation that's probably not, but produces interesting philosophical questions anyway ("what would it mean if time travel paradoxes actually could happen or the past could change? what if somebody could be Dead and then Not Dead After All? what would that look like from the point of view of a god who is outside time, just welcomed that person into Heaven, and then had that "undone" because time changed? Or would such events in fact be definitive proof of the logical impossibility of a god outside time?"). And then there's speculation that's just terminology taken out of context.

Anyhoo, feel free to take potshots at the speculation above, or indeed at my speculation about the nature of free will (another topic on which, definitively, Nobody Knows Anything) which, I promise, will turn up in any thread remotely related to free will, consciousness, or mind vs. brain.
