Although the idea of a time machine is popular, thanks to writers like H. G. Wells, the author of the famous book called "The Time Machine," time machines and time travel are not real. Time travel appeals to the imaginations of many people, because time travel is something many people would like to try. Is there any person who would not want to go back in time if given the opportunity? There are so many historical events people could witness in person if only they had access to time machines. There are so many famous people throughout history that people could meet, and have pleasant conversations with, if only they had access to travel on a time machine.

However, even though the time machine is not a real invention, there is a way that people can travel back in time, at least in their minds. Time travel of the mind can be accomplished by reading books. When you read books by authors you like, you not only experience the story, but you also gain knowledge about different historical time periods, environments, cultures, activities, and people. Reading books also enables the avid reader opportunities to silently "communicate" with the authors. How can this be? Authors write books for their audience of readers, and authors wish to communicate something to their readers. If you are reading a book set in another time period, and you understand what it is that the author is trying to communicate, you have, in a certain sense, gone back in time.

It is not possible to go back in time. The laws of physics do not allow such. And there are way to many paradoxes that could occur. What is really interesting though is that when close to objects with extremely large masses time slows. Next to a pyramid time is slower by like 0.0000007 seconds. And the satellites orbiting earth constantly have to reset their clocks because they are further away from the giant mass known as earth so time is faster for the satellites. So if we could fly a spacecraft in orbit around a black hole(largest mass known to man) we could dramatically slow down time. Say we spent 7 years in orbit that would be about 50 years back on Earth. And in a way we just time traveled. One could also travel as close as possible to the speed of light and slow time. So in conclusion it is not possible to jump from time period to time period but it is quite possible to slow time and in turn 50 years could become 7

The problem with time travel is the assumption that time is linear. Even more crucial , however, is finding out what time really is. Do we even know what it is? As far as I can tell it's nothing but change or things moving. Without movement how does time pass?

Someone mentioned time travel in the mind and this is the only form of time travel I know of. But even then, you're "going" to the past or the future within the context of the present. Think about this, if you were able to go back in time the way people imagine in movies would you really be in the past? Wouldn't you still be aware and in the present? I don't see this so much as the past but as an alternate reality existing in the same exact moment as the supposed present that you left. All experiences take place in the present, there's nowhere else to be.

Yes, it is possible to go back in time. Here's how you can time travel to the 1950's.

1. Pick up the Yellow Pages.
2. Look up the Republican National Committee.
3. Call your local branch.
4. Find out when they are having their next rally.
5. Attend.

Smile, you have time travelled to the 1950's!

If somebody could goes back in time and kills the human ancestor. When he comes back to his time, the exact time he left, he will find himself and his time machine surrounded by Gorillas and chimpanzees with machine gun ready at their hand to kill him.

It is better there will be no time machine.

According to Eisenstein's theory of relativity time and space are connected. Which when it comes down to it, it means that the faster you go the slower time goes. You can slow down time, and if you were able to reach the speed of light, you could stop it. But it is not possible to go back in time.

No. I once heard a very convincing argument by Stephen Hawking of the scientific proof of why we can't travel in time. He convinced me!

Not that we know of at the moment. But maybe sometime in the future it might be possible. We will just have to wait and see.

Who knows, perhaps someone has done this, but is still stuck in the past.

If you can go more speed than light, it is said to be possible
