That's the 100 million dollar question. If you could find a way to travel into the past or into the future, you would be the richest man or women on the planet.
That depends: If you can go from one place to another without traversing the space in between then you can time-travel.
The Apollo spacecraft that carried men to the moon and back in the 1960s and 70s, took about three days in each direction.
Not that we know of. There are likely to be serious problems associated with time travel. Such as paradoxes. If a "time travel box" had been developed, it is probable that a future civilization would have travelled back in time to eliminate its invention and these paradoxes. [Which poses its own problems for the traveller!] I rather like the definition of time attributed to Ray Cummings in 1922; "Time is that which prevents everything from happening at once."
Molly Moon's Hypnotic Time-Travel Adventure has 392 pages.
The moon doesn't actually travel in a straight line; it orbits around the Earth in an elliptical path due to the gravitational pull between the two. This orbit appears as a curved trajectory from our perspective on Earth.
You cannot travel back in time.
you can't travil back in time
I don't know cause time travel has never actually happened (yet) so you never know what could happen if its never happened before...
Time travel isn't possible.
Moving back and forth in time is called time travel.
Well, if somebody actually ever tried it, there would obviously be an associated date. However, since nobody knows how to actually go about to actually do time travel (it may not be possible at all), it seems that time travel is more something that is talked about in in the abstract, rather than somebody actually trying it.
Time travel.
Not currently.
Because time travel is a complicated procedure that always contradicts itself.
no way! if people cant time travel now how do u expect them to do it back then!
You cannot travel backwards in time
Unfortunately, the ability to travel back in time is not currently possible. It is unknown to us what time travel requires, be it speed, distance, location, or what is capable of making the trip, if such a trip is even possible.
