The same way you went back in the first place! How elementary! :)

"if you went back in time, how would you get back? :)" Hahahahaha your right since there is an infinite number of parallel universes the time traveler has to be very lucky to guest the one universe that the time traveler came from of the infinite number of paralell universe to return back XD

Well said Kage.

Its possible to travel faster then the speed of light, its just impossible to accelerate matter trapped in our space-time past the speed of light. In our frame of reference yes C is constant and cannot be exceeded but there are other ways to by pass the ''acceleration'' albeit being theoretical and well beyond our current technology. Tachyons are an example of hypothetical particles that travel faster then light and do not violate causality.

Wait. :)

The problem is that the speed of light is believed to be the highest speed at which something can travel, so it is unlikely that we will be able to travel into the past. As an object nears the speed of light, its relativistic mass increases until, at the speed of light, it becomes infinite. Accelerating an infinite mass any faster than that is impossible Pythagorean rule L122 = (X2 - X1)2 + (Y2 - Y1)time(1 - (U/c)2)1/2(U=speed, c=speed of light) dilation factor

no matter what u cant go to the past before the machine was created. u wouldnt be able to prevent yourself from being born like the movie time machine he couldnt save the girl because the girl was the reason the machine was createdif she lived the machine wouldnt be there thus making it impossible for her to live |
