Is it possible for anyone to invent time machine?

Well i don't think it is possible....but if it is created it will be great...but the cost will be very high...many unsolved mysteries would be solved...hope someone invents it.. ;)

Nope.  You'd have to INVENT the thing, and nobody would use it.  \n\nBut PRINT out the thing, then SCAN that into your computer. \n\nGood luck and Happy Computing!

Time travel is possible when we travel forward not backward. IF you look to the history books there are no such thing of human come form the future. So that is the proof that has defined the theory that we can't go to the past. There are theory that we can move forward by using the method of speed. Once you increase the speed of travelling the time will change very fast, and you might be in the future. But to have that kind of machine to bring you forward needs a lot of discovery especially about the strenght of metal, fuel, speed, and a lots more. You can get the theory about speed from einstein. Whatever you want to know about it, you can get it there, BUT eventhough you learn about time travel, you won't get that technology while you still alive. Maybe you can use that information just for you knowledge. Not more than that.

Currently there is no answer to this question.  Mankind will not know this until 1. We make contact with a time traveler or 2. We know ever thing there is to know about physic and the universe.  Time travel may be achievable but it is possible ; no civilization has be in existence long enough to figure out the solution.....If there are time travelers in the Universe now we might presume they would not make their presence know to us. We would be mere babies in comparison to their intelligence. So the answer is yes or no.

Possibly although Stephen Hawking once said that if time travel existed, we would see plenty of tourists from the future already and we would have historic accounts of them. There are plenty of theories of how it could work but no definitive solution has been developed.

I believe that there will never be something like that invented. However you might cheat a bit (not in the near future). You could use a device that copies everything in your brain everyday. Next you would need something to form your body when you die. That would be best done when you are younger. So when you die a machine automatically brings back you to life and you then go and install your latest memories. In that way you lose only the most important knowledge and that is how and why did you die! Personally I believe that you must not even try to live indefinitely because we are here to evolve and nothing more...

time machine can be created if we somehow catch the light rays which are currently present. what i want to say is that whatever is happening during this particular second is characterised by light rays. if we keep record of light rays of say  1st feb 2001 we can go back to that day.

Both time travel/time machine and cold fusion have theory, scientific theory on how it can be done and accomplish.\n\nBut to bring a scientific theory into practical application, it will take years of experiment, and trial-and-error experimentation. \n\nSometimes coming up with a practical application can take decades or centuries due to limited technology.\n\nIn example, Black Hole, it was an old theory that Black Hole exist, but only in the last 10 years when scientific observation and space exploration confirm black hole do exist, among the technology use is the Hubble telescope, which were unavailbale quarter of centuries ago.\n\nOn the fusion side, its harder to create fusion than fision. The energy requires and the scale or scope of the work. But maybe sometimes in the future, someone might stumble into a way to create a tabletop fusion.

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

That is a scary thought, just one wrong person or even one wrong move and the world could be thrown into a parallel time or alternate universe, but would someone with a time machine be able to fix what went wrong. Then I think of what good even I could or what  I would want to go back and "fix" warn myself or loved ones of mistakes, prevent some deaths, but I know that this is not my place and I would not want to "play" God, Greed would probably play into it and I would want to play the lottery or something equally greedy. Great Question!!! Thanks for getting me to think about this.

Make a time machine and go back to the seventies.

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

It's not necessarily impossible according to theory, but given our current technology, it's out of the question.  There's a lot of trouble with time travel theory, including multiple paradoxes.\n\nThe most famous paradox is, of course, the grandfather paradox.  It goes something like this: One day, after you've built your time machine, you decide to travel back into the past to shoot your grandfather before your father is born.  Here is the major paradox, if you suceed in killing your grandfather, you couldn't be born to go back and shoot him.  Just as well, the conditions required for you to shoot him couldn't exist and thus he lives.\n\nStill on the 'travel back in time to shoot grandpa' string, several other things could happen as well.  You could be transported to an alternate timeline, similar to ours, but not ours, and whatever you do there doesn't affect anything in our time line.  You could go back and try and kill your grandfather, but you are thwarted in every attempt, which tends to imply some sort of destiny or grand scheme.  You could try to go back in time but are ripped to shreds because every fragment of your being wants to be in its natural time.  There's a million and one other things that could happen.\n\nThat, I believe, is not necessarily answering your question, though.  Time itself is not understood by physicists even now.  What it is, no one is quite sure!  (However, I'm fairly certain time is related somehow to mass.)  One thing that's always for certain is time moves forward in a very linear fashion, cause followed by effect otherwise called casaulity.  I can't say one way or another why exactly we can't go back in time and I won't say it's not possible, some theories say it is.\n\nHowever, I believe Stephen Hawking offered up the best proof against time travel to date: Wouldn't there be time tourists from the future visiting us if time travel was feasible?

Under Einstein's General and special theories of relativity, time travel is considered possible. Stephen Hawking has speculated that it must not have been discovered to be practical as we have not seen tourists coming from the future to visit us.

yes you can. it takes you back in time...or you get to see the future..this is how time machines work.

Assuming time travel is possible, I think such a senario might be possible.  The trouble people have with time paradox lies in the assumption that every thing in the universe shares the same time line.  Why should that be true?  Here's an example:\n\n\n------  X  -------------------  Y  ---------\n\nAbove is our theoretical timeline.  Y represents me, in the "present".  I use my time machine to go back to X, before my grandfather sires my father, and kill him.  Logic dictates that I shouldn't exist.  What I'm suggesting looks like this, instead:\n\n---------------------------  Y  ------------\n                             \n\n---------------------------  X  ------------\n\nX & Y still represent me & my grandfather, but each of us now possess our own separate time line.  Instead of "going back in time", I simply hop off my timeline & onto his.  I am now free to perform my assassination, without consequence to me (beyond the obvious legal ones), as I was not born on this timeline, but my own.  Whether or not I can now return to my own timeline is an entirely different question, however.

I would go to the distant future and speak with people who perhaps allready have the time machine so I could understand how to use it carefully without disrupting the continuum. I would be careful on going to the future to get reports on sports games and the stock market because each future you visit is only one particular future, and with each passing second it creates a completely differrent future. I also might take christians and other religeous fanatics to the far distant past to prove to them that evolution occured once and for all and their bible thumping is basicaly meaningless. However this could also be dangerous because any foreign disease on us, or exhaled by us that was exposed to the primordial world could totaly change what we know to be current history. Every invention created by us happens very carefully, we make nothing before we are ready. If (in total speculation) a future time traveller visited the past he would have all precautions accounted for, such as disease, mistakes, and keeping a low profile. In our century we have no such precautions. So if I ever did get a hold of a time machine, I would return it to whoever it came from. Another problem with using a time machine to change the past or "the grandfather" paradox is Richard Feynmans theory of "a particle will take every possible path in space time" meaning if I went back and changed a past, I would change the past in a totaly differrent time frame then the temporal continuum I am used to, so when I returned everything would be the same. However I would be still messing with the universe. Theirfore if I ever found a empty time machine I would indeed leave it alone, or return it to the big temporal lost and found. We are not ready for such technology, and probaly wont be for a long time.
