We're constantly travelling in time, but always forward. If it were possible to travel BACKWARDS in time, millions of people would go back to try to prevent the extinction of the dinosaurs. Millions of others would go back to kill Adolf Hitler in his youth, a well-intntioned move with numerous disaterous potential unintended consequences. A few people would even go back to see to it that Adolf Hitler not only lived to adulthood but also led his fellow Nazis and the Axis Powers to victory in World War Two. Eventually, even the most-advanced imaginable technology and scientific knowledge would work its way back to the Neanderthals and the Cro-Magnums, who would then use it to alter thier OWN futures and ours. The ramifications would be endless. Because of the imperfectness of human beings, we'd never be able to get this fiasco under control. Therefore, I conclude that travelling back in time will never happen.

Time travel violates casuality. The universe does not tolerate contradiction. No time travel in this universe.
If we allow infinite sheaves of parallel universes, alternate realities splitting off every time a metaphoric decision is made, then time travel is irreversibly entering an alternate reality. The bottom line is that each possible universe will be massaged until time travel is impossible or undiscovered.
If there were a universe for every possible combination of events then it would make no difference what choices you made moment to moment because you would be making all of their possibilities anyway. But it does make a difference - try reaching deep into a running garbage disposal.

no, at least not back in time. If we ever invented a time machine then we would have an infinite amount of time in which we could travel to and infinite time to travel to it. Given infinite time to travel, humans would collectively travel to every possible time in every possible place, and you would therefore see tons of time travelers swarming all around you. However, if this theory is true, it doesn't mean we won't ever be able to travel forward at different speeds.

If you read the newspaper...
...physicists have already mathematically proven that it is impossible to go into the past. However, they have not proven going into the future.
However, you are time traveling into the future at a rate of 1 second per... uh... something.
Furthermore, if time travel were possible, there would be time travelers lurking.
Even furthermore, the future is not yet written until we get to that given time.

i've got faith so, yet no longer likely for many hundreds of years. First, there'll would desire to be super advances in aspects technology, synthetic intelligence, and propulsion structures. The starship will would desire to be built of an particularly easy-weight yet good textile; a intense grade of guy-made intelligence will would desire to accomplish lots of the monitoring, maintenance, and maintenance mutually as the team is in some style of triggered torpor; and the rigidity will would desire to be easy-weight, sturdy, and fairly effectual (perhaps a million/20 g).

It is not possible not to travel through time. What time is it? What time is it now? Can you tell the difference in time? It is because you traveled through time.

Gravitational Time is different at different parts of the Universe.So as you travel to different locations in the Universe you would experience time differently.Perhaps outside the Universe time is infinite.
Since time of infinity is indeterminate we are not really able to understand it. We can only measure time relative to the motion of the earth's orbit around the Sun.
No One really understand our Creator's time. As we even exagerate or underestimate it.

I DONT REALLY THINK SO...
IT IS AGAINST THE LAWS OF NATURE AND MOREOVER, IF THIS WOULD EVER HAPPEN, IT COULD BE DANGEROUS AS IT MAY ALTER A PERSON'S FUTURE OR EVEN PRESENT...
