Yes it is possible i always wanted to be a scientist my name is reshma i like to invent a time machine where i could travel from present to the future and the present to the past. I think u have the same thinking.

Even among physicists, there is a difference of opinion about whether time travel is possible.
Of the currently known laws of physics, there is no law that absolutely _forbids_ time travel. Some physicists have proposed ways that involve a serious warping of spacetime (e.g. wormholes). None of the proposed methods involve traveling faster than light; transmitting information faster than light _is_ considered impossible by current laws of physics.
But many physicists believe time travel is impossible based on logical contradictions of causality. For example, time travel would allow you to receive a reply to a message, before you actually sent the message. This creates a lot of logical problems. For example, suppose you receive the reply (on Tuesday), but then when you're supposed to send the message (on Wednesday), you decide not to send it? Is that even possible?
For that reason, many physicists believe that there is probably some not-yet-discovered law of physics that says that time travel is impossible. But nobody is 100% sure.

I WANT TO BELIEVE !
1. things go approaches light speed, its mass will increased. 2. hypotetical partical faster than light speed is Tachyon.
if u watch back to the future and the time machine, then u r time travel forward, bcoz u have just spend hours watching those movies, huh.

No. Time travel is NOT possible. EVER.!!
If you don't believe me, learn to understand Einsteins work.

Einstein didn't say you couldn't go faster than light. He just said that as you approach the speed of light, it would take infinite energy to achieve it. Infinities are an indication that the equations are off.

I just came back from A.D. 3000 and asked them, and they said they tried but to no avail! So, I guess not!
I'm just kidding! I don't think so. If anybody can, then God can.
