Is time travel possible?

In theory, the faster you move, the slower time advances for you. If you were to move at a speed approaching the speed of light, you could slow time enough that you could "travel" forward. It isn't really time travel, but whatever works...\n\nAs far as I know, traveling backwards definitely is not possible; time is a construct, something that only exists in one's mind. It is really a rate of change; the change can only occur in the positive direction, so traveling backwards is out.

are you trying to suggest that time travel in the reverse direction,ie, travelling to the past, is possible..\n\nif thats the case then anything can have an opposite of it, like mass etc. which are conventionally taken to be positive

Time travelling is a very difficult topic.\n\nYou can supposedly travel into the past if you travel faster than the speed of light but this involves getting a source of infinite energy as when matter gets closer and closer to the speed of light its mass will dramatically increase.\n\nThis is said to be very unlikely but general relativity says it may be possible on highly unusual circumstances.\n\nWormholes, permitted by general relativity,  could be possible only if it is traversable.\n\nIf you read general relativity and objects at speed of light you get time, space and gravity based dilations where light appears to be bent by gravity and arrives at an object at different times.\n\nYet again the object has to be travelling at 0.99c or faster!!\n\nI says time travel will never happens but i wish it would.

I watched a Discovery Channel Feature bout time and space,\nand one guy said that the present laws of Physics do not\nprohibit time travel... so it is a possibility.\n\nThe concept is so real that I think people from the future are walking amongst us today. They are more stronger, tougher, faster, and smarter. From the future, they are sent to our time to rule everybody else. I know one. His name is Ben Wallace.

it is believed by many time travel is not only possible but that it has all ready begun. look up time traveler john teeter or it may be john titor .tell me what you believe the truth is that you see

One type of time travel occurs routinely here and now: our inexorable one-way drift into the future. Einstein's special theory of relativity revealed the possibility of accelerated travel into the future \nSuppose a person spends a year in a rocket that's traveling slightly less than the speed of light. Because motion at such enormous speeds drastically slows the clock for the traveler, that person could return to Earth to find that many years had elapsed at home. In that way, a traveler could leap into the future.

the answer is - it depends - on a lot of things\n\nI hate to answer a question with a question but here goes ...\n\n- do you mean in theory or in practice ??? (in [einstein's relativity] theory it is possible to travel into the future - all you need to do is to go out into space for a while - the time here on earth will continue to progress at a normal pace while time for you will progress more slowly - when you come back you'll have essentially traveled into the future - not quite a time 'machine' but same effect

I have not seen or met a time traveller. However their is such a thing as a gauche horizon. Basicaly when you create a time machine you cannot travel back before the time machine was created. So sence as far as I know, no time machine has been invented as of yet. It would be impossible for a time traveller from the future to experience what life is like in our historical period. For instance if the time machine was created in 2500 they may start having time travellers from the future coming back for anthropological surverys. However they could not visit 2006 because the time machine was not yet invented.

I really don't think it's possible to travel through time, though...

I doubt it, I think it's just one problem that someone put forward to explain why Time Travel would be impossible, some of the first examples given were the Grandfather Paradox and the Butterfly effect but loads of Oxymoron's exist such as "American Military Intelligence!"  but what's the point of being an oxygen breather if you can't be a moron :0)

Relativistic time travel is possible. Time passes more slowly for an observer who is in motion relative to one that is at rest. The next trick is to define which is which, which is why Einstein won the Nobel Prize (although it actually wasn't for relativity, but that's another question).

time is not linear and people can shape shift, remote veiw, and time travel. For the answer to your question, simply sit and meditate upon it, it will become clear....you already know.

You can travel to the past but you can not travel to the future BECAUSE it did not occur yet.\nCheck the latest Physics web sites on this topic of time travel

I think i read on here somewhare that Albert Einstien said that time travel was impossible but time seeing was a possibility.

Yes, but you can only go to the future, not the past

Sadly, I've actually heard about this before.  I can't believe how much useless junk I put into my head...I'd say pure fiction.  Its just more likely that he was some bored computer geek trying to get some attention.  Its still unclear whether or not time travel into the past is possible.  Based on current science I'm leaning toward the impossible side.  Oh well, 2036 will be here soon enough.  Then we'll know for sure.   ;)

Theoretically possible. See: http://www.pbs.org/wgbh/nova/time/through.html
