My world.

Tachyons are supposed to travel faster than light, not back in time.

And in doing so they are meant to travel backwards through time. They aren't meant to create paradoxes since they can't send information into their own past.

Of course, they are all hypothetical anyways

I love how this went from the Matrix to Tachyons.

TBF,

xt and yt are dimensions with xt being a dimension of choice and yt being another dimension that modifies an infinite amount of points along the xt axis. Void pointed out that it was redundant but I would say that yt for choice is only as redundant as y is for spacial placement. I would accept another definition for yt but it seems to me that our future would spread out in front of us as a cone of possible choices contained within three dimensional time rather than just an angle within a plane of time.

At any rate talking about 4+ dimensional time has demonstrated to me that I need to read up on string theory.

I only really said that yt would not represent time alone, and thus would not be a dimension of time, it would represent entire 4-dimensional universes, you cannot have multiple divergence of time inside the same space, so each choice, resulting in an alternate dimension, would not be yt but a(xyzt), b(xyzt) c(xyzt) etc....
