if time's just the virtual dimension determining
how long light needs to pass space, not likely -
but since there are mirrors, all virtualities exist.

I can remember when I was a kid, back in the Stone Age, my teacher and class laughed at me for suggesting that other planets could be beyond what we can see. They thought there were only 9 planets. (Well, laugh now witch!) That said, I think there are many possibilities we wouldn't normally find logical right now. You are far more sciencey than me though!

Hmmm... not sure I saw anything all that new there; Hawking and Penrose already posited the Entropy = Arrow Of Time idea - and Hawking even initially said that during the "Big Crunch", time would run backwards (later backing off that idea).
Title's also a bit weird... Could time flow backwards in another universe? More importantly... could you tell that time was flowing in a different direction? Answer: probably not.
The basic idea's sound though. Although I'd phrase it differently; when there are multiple probable outcomes to particle-particle interactions (eg. feynman-style sum-of-many-histories), the universe picks the outcome which increases the total energy of the system as a whole. On the level of particles, time does not exist; any interaction affects the whole history of all particles concerned - this allows the entire system to act as a relaxation network, where observers only see the net effect which increases entropy. The distance from an interaction to another interaction (in terms of network nodes) decreases the effect of that node on others.
One of these days I'll write this stuff down and do the math ;-)

Sorry - typo. Meant "increases the total entropy of the system as a whole"

How do we know it's not going backwards here, right now?
moducOct 19, 2010
Because it doesn't. Time never goes backward, unless you change its definition. Say you have a video, and play it backward. When doing that, time goes forward. Same for physical world. If somehow, things all go reverse, time still goes forward. Things just go reversed.
Now, let's think if it's possible.
Take the moon goes around the earth. Could it go backward? If there is another physical force like other people said, then it doesn't go backward in the sense of reverse of entropy, but rather just go reverse like you go backward because the force of your feet pointing a different way, nothing major here.
Ok, let's consider the case of the same those force, but just reversed due to some kind of odd entropy that verses it.
You know that if the earth and the moon pushes each other, the moon won't go around each other.
It just defines logic that pushing would mean getting things together.
Would any kind of reverse entropy that allow that kind of push that things moves closer? Probably not. This is not physic anymore, and it's math. That's when it becomes constant through out the universe.
How about not pushing, pulling, but it just goes reverses. That's normal. If it's been going the other direction, it would continue to do that. If going forward, the suddenly reversed, then the "reverse entropy" only occurs short amount of time, and unlikely.
How about the other case, where all forces just reverse. When that happens, it's almost true that entropy reversed. When that happen, I think physics equations are the same, but things would fly either in chaos, or it will reach equilibrium at some point, then same old world, just different physics. This can be simulated through computers. Probably things just keep flying out, like light.
One more case, where all the forces are the same, but the "fabric" of the universe somehow allow things to move the opposition. That's by our definition, we just call the force the opposite, and physic equation would be the same, just different force.
How about when the "fabric" just go nut, and not reversed, but just different. Well, that's when time is not going backward, but it goes nuts.
The question is that is there such a thing as we call "fabric" in the first place.

That is incorrect. Shoving is the answer. Shoving wil protect you from the Terrible Secret of Space.
brad324Oct 19, 2010
Considering time is 1 dimentional, time flowing backwards would feel the same as time flowing forwards. If you travel 50mph eastbound, it does not feel any different than travelling 50mph westbound. The only way time would feel different is if the speed in which it is travelled were changed, as it would change the relative "constants" such as gravity, but even then, would any conscience mind be able to notice the difference? If our entire lives were lived in 1 second, would our minds still process it at the same rate as normal?
glbernsOct 19, 2010
Theoretically, in other universes the rules of physics are different. light may move at a different speed, there may be other forces than gravity friction strong and weak forces. there might not be those. You want to define time by the rules of our universe. In another universe those rules don't exist.
agmlauncherOct 19, 2010
But the point is that it's all based on relative perception. The only way you'd notice something different is if you had an alternative to compare it to.
kidcelticOct 19, 2010
I'm so tired of theoretical physicists presenting incomplete, incoherent thoughts just to get their 15 minutes of fame. What ever happened to scientific method, peer review, etc.?
glbernsOct 19, 2010
Agreed. This is not testable. Although, maybe some mathematicians can get to work and draw something up. Thats the only way this can be proven. Until then, this is just an interesting thought.

Time does travel backward, but we just can't realize.
Closed AccountOct 22, 2010
:) actually travel does time backward,
but we realize only upon overbooking.
druceOct 19, 2010
This assumes that time flows forwards. This is kind of like saying "could height flow downwards in another dimension?". When will we figure out that half of our problem understanding time is we try to rationalize out limited perception of it.
We accept that stuff doesn't really get smaller when it gets farther away from us. It is just a tool that our brains use to process depth, but we get stuck believing that "now" is anything other that a similar construct used by our brains to make sense of the world.

If there is no time in some universes and time in other universes then time is not a dimension or a reality, it is only a relative yardstick for measuring rates of change.

if one assumes an multiverse/omniverse of infinite "time" & "space", all conceivable (& yet inconceived) possibilities have happened, are happening, & will happen... now go read alice in wonderland ;-)

Nonsense!
No seriously, there is nowhere in this universe or any universe where time does not flow. Time=Space=Existence. Something with no time therefore CANNOT EXIST.Comment is buried, click here to see the rest.
hackwrenchOct 21, 2010
How about this, then: In other time spurs of what is essentially the same universe, time does flow backwards only we're always on a time spur where this doesn't happen. Meanwhile in other "universes", Santa, the Tooth Fairy and the Easter Bunny do exists and Marty and Doc are travelling through time.
