anti time

[jamey2k9]

I was daydreaming and I thought about time running it's infinite path and then I thought would it be possible that there's anti-time and what would anti time be any ideas

All comments welcome

I don't know what you mean by anti-time? If you mean in the same was as matter and anti-matter, then I'd say no, as they are not anti-space...

Just because matter has anti-matter, does not mean that time has anti-time. Time is an artificial measuring device like length. Using this logic there cannot be anti-time just like there cannot be anti-length. Distance measures are always positive.

In the theory of supermanifolds you have "odd" time.

 

That is a map [math] \gamma : \mathbb{R}^{0|1} \rightarrow M[/math], which in local coordinates is [math]\gamma^{*}x^{A} = x^{A}(\tau)[/math] if [math]\tau[/math] is a coordinate on [math]\mathbb{R}^{0|1}[/math] and [math]x^{A}[/math] are the coordinates on [math]M[/math].

 

It is odd as it carries Grassman parity 1. In particular this means [math]\tau ^{2}=0[/math].

 

This is more like a super-time rather than an anti-time, but it is the closest thing I can think of. Also see supersymmetry.

Again, in the category of (smooth) supermanifolds you can define an odd Riemannian structure. In the same sense as before it is like an "anti-length" of sorts. I don't know much about odd Riemannian structures, they are on the list of things to work on next.

talking long shot would there be any possibility of there been anti-time

[Airbrush]

"...any possibility of there [being] anti-time[?]"

 

Sure, anything is possible, just not probable. There is time dilation. In the most far-out episodes of The Universe on the History Channel, they never mentioned "anti-time". Nothing about anti-time on wikipedia, and they even mention time travel. The concept "arrow of time" implies time is positive. Has anyone heard of "anti-time" in scifi? Not once did I ever hear Mr. Spock mention anti-time in any episode of Star Trek. They just travel faster than light and go back in time.

[jamey2k9]

there one episode of star trek were they encounter some anti-time vortex paradox or something like that I was half asleep so ha:D:-p

[Klaynos]

I still don't get what anti-time would be...

[hewj11]

I agree. What would anti time be? Non existence? traveling back in time? Or like a anti universe?

[Airbrush]

You are not alone Klaynos, nobody gets what "anti-time" would be. Time slows down for moving objects, but it doesn't seem to reverse. Can time speed up? Does time ever stop? Time travel only occurs at Montauk Point Long Island.

An anti-universe is possible, because anti-matter certainly exists.
