A theory is, light particles can act in reverse time. Two subatomic particles do seem to communicate with each other regardless of how far apart they get in space & time. Its a theory that rests on a sort of time travel called Quantum Retrocausality. A backward concept that time can go backwards. Lasers, prisms, splitters, & fiber-optic cables can be used to detect non-local signaling between entangled photons. Experimenting with those and the above light particles just might work. What do you think?

Anti-particles behave like normal particles running backwards in time, but we have never observed anti-atoms or anti-molecules, let alone anti-matter galaxies. It is not known if they have anti-gravity.
In my Fractal Foam Model of Universes, there is a sub-universe and a super-universe, both running in reverse time relative to our universe. Because they run backwards, I assume they are made of anti-mater, but on a vastly different scale than our regular matter.

actually time can move backward in case you are a subatomic paricle and you aren't bound to the classic laws of physics.
At least it appears that this is the case for such particles.
unfortunatly time cannot run backward for you as human being cause it would violate the concept of entropy on a too large scale.
To solve that riddle it seems necessary to imagine spacetime as to be something which has a few more dimensions than those we commonly believe in.
unfortunatly this is higly theoretical, and it seems we have to wait another few decades till experiments in particle accelerators may come up with something more than just hints on how our universe is possibly working.

No, our concept of time is based on observing motion through space. If all motion stops our concept of time stops, if motion goes backwards,what is backwards? is backwards,backwards or is backwards, forwards, who decides?? Time stands still and the world moves forward, even if the world was going backwards we would still think it was going forward so time will always appear to go forward no matter how warped our concept of space and time becomes.
are you confused yet?
the end (or is it the beginning, I'm not really sure)

Time does move backwards, at least it does when I'm at work!

Unfortunately, some of the symmetries will fall apart if you allow that and the universe decays ... no cigar.

Most of scientists believe that you can only travel "forward" in time, never "backwards".

I like to keep it simple....if, what goes up must come down..then, what goes forward must go backwards. that really is the duality of existence......even on a quantum level...methinks.

Time is a zero-point dimension.
It is not a material phenomenon and no one can move it around or move around in it.
