The article can be found here, entitled "Big Bang May Have Created a Mirror Universe Where Time Runs Backwards".
I know any notion of backwards time is probably a dead horse in this site, but given this is not a topic of time travel based on some theoretical non-linear time model, is a mirrored universe with backwards time even theoretically possible?
Wouldn't backwards time violate the second law of thermodynamics? Wouldn't reverse time reverse rate of decay (e.g., reverse aging)? Wouldn't the reversal of time imply the future is predetermined (e.g., in order to reverse a falling person, the person falling in the first place is a fixed event), et cetera? I believe even determinism can be ruled out because there exists non-deterministic configurations in newtonian kinematics.
I know that, perceptually, we would not notice a difference because our intuitions of past, present, and future remain intact. But wouldn't the physics of backwards time rule the claims of the above article absolute junk science?

It's not junk science, but the article is extremely superficial and not very accurate. It has this: One theory, proposed in 2004 by Sean Carroll, now a professor at Caltech, and Jennifer Chen, then his graduate student, says that time moves forward because of the contrast in entropy between then and now, with an emphasis on the fact that the future universe will so much more disordered than the past. This interpretation of the arrow of time is many decades old, and is not credited to Carroll and Chen.

A little bit of digging allows one to find the original Scientific American article, which links (and I wish every science article did this) to a journal article from Physical Review Letters (preprint). PRL is very unlikely to publish "junk science."
I also think the case is bolstered by the fact that they did simulations, as the Scientific American article elaborates on a little more than your linked article, and that these simulations showed two universes always arising.
That being said, these articles were published four years ago, and the "two-universe theory" (I made up that term) hasn't caught on. The reason is that it is no more or less provable than any other theory that asserts the existence of multiple universes to try to explain some kind of physics.
I typically think of "junk science" referring to pseudoscience (think astrology, for example), faked science (think anti-vaccine movements) or things that look like but aren't science (think "human design"). Under that rough operational definition, this idea doesn't qualify as "junk science." But it does qualify as a largely unprovable theory about the nature of the universe.
