Professor Predicts Human Time Travel This Century

Points to ponder:

Ren, you are right, but keep in mind that he is not saying you could travel to a time before the machine's existence. Using short-lived particles example, the machine was built before the particles were inserted, so no problems there.

The past is unobtainable, regardless of the specific reason. Maybe it's my timeless theory. Maybe it's the Deutsch theory that travel to the past is actually travel to other universes. Whatever it might be, I propose that 1) if it is possible, then someone in the future has already figured it out, and 2) it is not lethal to our existence, because we are still here.

Choobus, this is an idea that's been floating aroud for awhile (I first heard of it about two years ago) - it builds off the anomalies discovered by rotating laser beams. I don't know if this analogy flies, but for the same reason particles make multiple laps around an accelerator, building relativistic speed, that laser energy could somehow accumulate through rotation. I shall see if I can find more on this for everyone.

yeah, I suspect these are the same "anomalies" that drove otherwise sane men to spend years and years trying to construct a perpetual motion gyroscope. At the end of the day it all comes down to faulty transformations between rotating and non-rotating inertial frames.

In any case, if the laser energy does somehow accumulate then why won't an extremely strong gravitational field be generated, which would destroy the machine? You can't invoke relativity to bend spacetime and not expect a strong gravitational field.
