ooh I really like this question. You're thinking about almost the same thing that led me to my theory of 1/0.
Yes, it is entirely possible for time space to become negatively warped and this is what my diagram known as the number circle shows you. So when the big bang occurred, it was as if time space came from negative time and dilated so much that it suddenly ripped into positive time through an infinitely small point (this is called the big bang). So basically, what your talking about with negative warps illustrates the idea that the expansion of the universe is really just like a negative lorentz transformation that is happening in all directions at once. Recall that a lorentz transformation is what causes an object approaching the speed of light to shrink in the direction of it's motion. So theoretically our universe was created by a speeding bullet that shot faster than the speed of light from a higher dimension, and when it did this, it was moving in every direction at once (since it was derived from a higher dimension, and that's why our universe expands in every direction at once). So the speeding bullet had some degree of absolute acceleration in order to cross the speed of light. Note. absolute acceleration is defined as the amount of acceleration you would need to go from whatever speed you're at to greater than the speed of light in a planck second or less.
So when an object exceeded the speed of light in a higher dimension it created our universe. Also it created our speed of light which is less than the speed of light in the higher dimension from which our universe was derived.
I hope I'm not confusing you. Let's run through a scenario. Let's say you send something faster than the speed of light. When this happens that object's space/time will fold over itself and this is what I call time/space inversal. So when your object crosses over the point of time/space inversal (i.e. the point at the speed of light) it will begin expanding into negative space/time. But to the new universe you just created this seems like positive space/time. So depending on how much acceleration your object has when it crosses the speed of light a new speed of light will be defined for that object and the universe it creates. If your object's acceleration is 1/0 when it crosses the inversal point then the universe you create will have the exact same speed of light as you do, but if your object has an acceleration less than 1/0 when it crosses the speed of light (which it probably will) then the new universe you create will have a slower speed of light. In this way all densities with lower speeds of light are derived from objects exceeding the speed of light in higher densities. The highest density of all is where the speed of light is 1/0.
So that covers space/time inversal which explains the big bang perfectly. The reason we have a certain cosmic background radiation image is because that is how the object that created our universe looked directly prior to making a quantum leap across the speed of light from a higher dimension. This quantum leap is what explains the perceived period of inflation. So the actual point of space/time inversal is skipped over due to the quantization of time ala classical quantum mechanics. The only way you can exceed the speed of light is to make a quantum leap over it.
So that is one type of negative warp that you speak of, space/time inversal. The other type is space/time "ex"versal. If we think of inversal as time turning inside out through an infinitely small point, we can think of exversal as time turning outside in around an infinitely large point. This will occurr when the universe is expanding at greater than lightspeed at less than planck scales.
well, hopefully that's enough to think about for now. That might be the most I've described my theory ever. Keep up with the good ruminations.

Now lets just assume that somehow we are able to warp space-time so much that it goes into 'negative warp' or time is dilated to such an extent that it flows backwards and space-time is folded over itself. Now if this occurs, distance is folded over itself, does this mean that if a massless particle was moving with a velocity v, crosses from a 'positive warp' to a 'negative warp', its direction of motion would change because distance in inverted ?! |
