Well... yours is actually one of the most difficult questions of science ever, even though it seems so simple in conception.
Travelling forwards is easy. Just lower your relative state of motion to that of the rest of the universe to near zero, and you will effectively zip forward in time. Sounds complicated? Throw a piece of meat in your refrigerator, why doesn't it rot? Because time for it has slowed because the rate of reaction for it has been slowed by the drop in temperature. An object at absolute zero is experiencing no reactions at all, and time is effectively stopped for it, while time for everything else continues as normal.
So basically time is a way of measuring reactions and changes of state in one body relative to the changes and reactions in another body. If one body does not change state (like a rock say) and another does (like a weed) then we recognize the changes of state for the second object as time passing.
How then, do we travel backward in time? It is a matter of changing the reference point of yourself to the rest of the universe. In effect, you would need to access the universe in an altered state.
There are two ways to go about this problem. The first is to alter the entire universe to match the pre-existing state or condition. Effectively moving the universe backward in time relative to your vantage. Since that is just a wee bit impractical, let's look at the second way.
The second way to travel backward in time is to move only yourself to a prior state of the universe. To do this, you would need to find a way to slip outside our universe (a feat which is barely even theorized at this time) and then, perhaps even more difficult, you would then need to manage to re-insert yourself into the universe at a prior state. Nothing currently on the scientific horizon is capable of doing this, although wild speculation on the topic abounds.
The worst errors committed scientifically on this subject are errors in the understanding of relativity as regards light and black holes. People mistakenly think that exceeding or travelling through these would result in travel backward in time. It would not, nor does relativity state such. Instead, it would merely -seem- as though time was travelling backward. The reality, however, is that this is simply a nifty illusion, not worthy of the credence sometimes attributed to it.

It depends on when you want to go.
Theoretically speaking, it is possible to comparatively travel forward in time because of a principle of special relativity called time dialation. These theories state that time passes more slowly on a faster moving body relative to a stationary body. The faster the body moves, the more time "dialates" relative to the stationary body.
This has actually been reproduced by observing the slight differences between the chronometer on the Space Shuttle and the one on the ground after a mission. The one on the Shuttle is slightly slower because the Shuttle is moving much faster relative to the ground station.
The faster you go towards the speed of light, the slower time will pass for you relative to a stationary observer.

Yes!
The physical body may not be able to move through time/space at will in any direction BUT, being anywhere in time/space at any time is possible.
I think in the movie Dune, they had it mostly correct, it will just be like folding a piece of cloth and moving from one point on it to another then unfolding it again....Once its unfolded your all the way on the other side, with hardly taking a step.
Trouble is, where ya wanna go?

Yes, and to amend a injustice so they can get their middle finger back, must suck being hungry all the time and holding little crop circle signs up, trying to catch a bird who will only stop for free birdseed. Oh, and because they destroyed their female and get exactly what they didnt want...homo all the time from then on with sex witha tube. Great Mother " Oryana " end up kissing native *** and worshipping a peace pipe with willow stick tobbacco, know why natives looked at things at all angles when europeans first arrived? because little four fingered aliens say hello the same way...can I touch it? native way superior in the future...cant wait ; ) X ^~

If it was possible to make a time machine then it would be reasonable to assume that at some time in the future one would be invented.
If that was the case then surely we would have been visited by people from the future!

Yes, once they figured out the speed of light in the past. Also, an inanimate object might be able to travel to the past but the the human body can't. The human body might not be able to handle the 'shock' of time travel. Some recording devices might be able to send back to past for recording.

We've been making time machines for centuries. We call them clocks.
Beyond that, no, time travel is impossible...except to travel forward at a rate of one second per second. And anyone who suggests that nothing is impossible in science is simply an idiot. MANY things are scientifically impossible.

Making a time machine is possible. Human travelling in a time machine and survive is physically impossible.

Nothing is impossible in science so keep hope may be one day scientist make time machine.

enable's look at information itself, information of ones self. computers have become smarter and smarter and interior the subsequent 10-2 an prolonged time, they are going to be smarter than we are. they are going to be waiting to compute speedier than our brains can. it could then be purely a be counted of time before a gadget will replace into "conscious" that it is a gadget and if it does that, then it has information.
