Is There Any Accepted Theories About Time Machine?

If you can travel faster than the speed of light in theory you will move backwards in time because the light from the present will not have reached you yet. So in essence you will be seeing the past, but moving without moving is the drawback seeing as that itself is impossible, because in order to move faster than light you will have to go a long distance, but you cannot stand in one spot and go back in time because you will not be moving anywhere.

If there really were any accepted theories about this, then the whole world would know about that.

That answer below has me confused.

Even theoretically, is there anything at all that associates moving faster than light-speed with moving in time in this way?

Surely you would have moved beyond light-speed but still reside in the same space-time? Therefore, yes, light from the "present", [or light from the present that's behind you], could no longer catch you, but you would still be in the "present". In the theoretical event that you could move beyond light-speed, how would that enable you to "see" the past, automatically?

I don't get the rest of it either: 'in order to move faster than light you will have to go a long distance"? Why? Light moves at light-speed as an absolute and it does so, mostly, regardless of space or time. Light moves at Light-speed in the long distance between the sun and my desk, and also at the short distance between my computer screen and my eye.

At the theoretically point of breaking Light-speed, why would distance suddenly be an issue? There seems to be a reliance in that answer on a correlation between light-speed, time-travel and actual spatial travel and movement that I'm really not sure about at all.

I'm not sure I understand how theoretically breaking light-speed would have you travelling in time, automatically: I wish he could explain.

I do agree with him, [I think] that practically breaking light-speed, for any body with Mass, might be difficult - because of this: E=MC2.

That equation has always suggested to me that for a body with Mass to even equal the speed of Light, let alone break it, you would need the Energy - which means ALL of it: All the Energy there is, all the Energy there was, and all there ever will be.

Human beings seem capable of doing a great many amazing things - given time - so maybe travelling in Time will be one of them, but I don't think it will be as a result of anything or anyone solid breaking Light-speeds.

You question was about theories:

There are many. None of them are even anything close to being "accepted".
