quantumbiocommunication.com — Physicists have always scoffed at the idea of time travel, considering it to be the realm of cranks, mystics, and charlatans, and with good reason. However, rather remarkable advances in quantum gravity are reviving the theory...

the reason you ants are so baffled by time travel is because you have yet to realize time does not exist. Time is perhaps the greatest illusion in the universe. Because it is something that exists solely in our minds. In reality there is no time, only changing atoms. Time is merely the brains way of understanding an existence where everything is in a state of perpetual change, including us. intelligence manifests the perception of time so it can control some of the changing atoms(you) within the group of changing atoms(universe) it is a part of. to travel in time would actually be to travel in change, which would mean altering the state or rate of change of all atoms in the universe except your own. changing them to the state they were in to coincide with what you see as the time period you want. in order to control time we would have to control the grand force that is behind the collective motion of every atom in the universe. Gravity. The only way to travel in time would be to the future. By freezing yourself which would slow time for you but by your perception in this slowed state speed time up for everything else hence travel into the future. as long as you keep thinking of time as something that exists in the environment and not just in you're head you will always run into paradoxes.

I dont care what any of you say. It was a good read, therefore dugg.

Good lord, not that site again, the one that gave us "the heart senses future events..." Physicists have seriously considered the possibility of time travel for years, so this is nothing new. As to why we haven't seen time travelers from the future, the time travel schemes that are so far theoretically possible do not allow time travel prior to turning on your time machine. The time machine must exist in the past to travel back to from the future. If you built your time machine now, you could only go so far back as now. Ergo you can't go back and give yourself the info required to build your time machine. On the paradox of preventing yourself from traveling back in time, IE the grandfather paradox, it would seem there are two solutions, either you are stuck in an iterative loop, which must end in you failing to prevent yourself; or there is a 'many worlds' solution where you are not in your own past, but part of a past event where "you" are prevented from time traveling by you. If you want to preserve conservation of time and energy, which going back into time would seem to violate, the latter solution would at least allow you to do so for all of the 'many worlds' as a whole. "Time doesn't exist/ is an illusion," is bong based physics...

We need to stop thinking about time travel and focus on traveling to parallel universes.

"Physicists have always scoffed at the idea of time travel..."The opposite is true. Over the last 50 years, it has pretty much been assumed that it is indeed theoretically possible.the laws of physics have never precluded time travel. Maxwell's equations have two sets of solutions: one describing standard wave propagation at the speed of light, one describing waves from the future converging on the particle.Feynman even proposed a theory for describing positrons as electrons moving backward in time. His feynman diagrams are useful to describe certain observed effects, and they clearly indicate particles travelling back in time!<a class="user" href="http://www2.slac.stanford.edu/vvc/theory/feynman.html">http://www2.slac.stanford.edu/vvc/theory/feynman.html</a>The "principle of least action" (which describes the trajectory of a thrown ball, and is set by the launching conditions), also applies to objects travelling in time (if they could, or do). It can be shown that this trajectory would never result in the object hitting itself in spacetime, or any of the myriad of other interactions taking place which would result in paradoxes.
