Yes, time travel is possible. That's the short answer.

You are travelling in time right now as a matter of fact. You are traveling forward at roughly +1s/s (one second per second). But that's not what you meant huh? Okay here's the longer answer:

Picture a stationary escalator. The power is off. You are standing in the middle. Cool. Now move up one step. Down two steps. Up one. You are in the same starting point but you did some space travel - you traveled in space. That took energy. Not enough to move the escalator - but took energy nonetheless.

Now fire up the escalator - flip the switch. Consider the travel up or down moving in time. You haven't actually moved in space cause your feet haven't changed position - remember that you actually had to step to another step before to travel in space. But you're still moving.... that's moving in time. Now, to go backwards in time (assume the escalator is going up) you'd have to exert a large amount of energy to overcome the natural forward motion of time by running down the escalator very fast while it was moving forward. To go forward in time - same thing, you have to expend a level of energy beyond that necessary to move you forward naturally. Anyway - thats about as good an example as I can muster using staircases and escalators :)

Yes. It is relative, though. When you look at the sky through a telescope and see a galaxy that is millions of light years away, you're seeing something as it was millions of years ago. If you could move at relativistic speeds like in Star Trek, you could get to that galaxy in maybe 25 years. But in the meantime, millions of years have gone by on Earth. So, at high speed, you can travel into the future, since if you turned around and came back to Earth, the Earth would be millions of years older. That's one example. There are actually lots of others.

Yes , you are traveling threw time now at the speed of light, Time is just something we made up to keep track of the seasons and when it will get dark etc. and we are all moving forward threw it .

That's funny you should ask. My family was just in the car and asked the same question. My husband think's it's entirely possible, but the technology has not been invented yet. My son argues that if we could, someone from the future would have already come back.

time travel will eventually be possible

the question is when you travel back in time, whatcha gonna do there and then...because of the 'grandmother paradox' you cannot do anything, because it will effect the whole timeline from that point onwards...and change the origin of your point of departure, so much so in certain scenarios you may not even exist to start the journey (see the paradox?)

phew...

Any travel is time travel. It is relative.

have you ever skipped a object across the surface of a body of water?that reminds me of a diagram i saw inside of a time machine once,but i didn't understand what i was looking at.then i heard this annoying pulse and realized it was time to get up and have breakfast...thermo-treated chicken embryos and the agitated and manipulated seed of the wheat plant soaked in a solution of bovine baby food...

It's theoretically possible, but all the ways imagined which may fit theory would be so impractical, energy-wise and time-wise, that we could never actually do it.

It's not possible. Stay away from your television......Wow! Look at all these Star Trek groupies!!
