The formula to travel in time

i have seen many times in discovery. it is said that if it is ever possible to travel on speed more than light, according to the Einstein law we will be able to travel in time. or some time they say if they can fold the universe they can get the speed and they can go any where in a very short period of time. i dont ever get the meaning of all those things as how it is possible to go in future or in past by merely having a high speed as light.

It's simple. For instance, let me give you an example. If you look at the sky and you notice few stars being brightful and shinning in their brilliance. To us it seems that those stars are being shun right at the very instant but in fact, the image we see up in the sky is actually coming to us after travelling millions of light years. By understanding this very notion, it becomes easier to also contemplate that whenever one can achieve the goal of travelling faster than the speed of light, one can actually travel so fast, back in space, as to see the past... like sort of rewinding back the tape... i'm sure this won't answer your every queries and I therefore, suggest you to look for more interesting documentaries out here on time travel and space exploration. It's definitely a very interesting topic to be discussed!

Hi medicguy, ur explanation is quite illuminating, and u have explained it very simply. :) Thanx. Well, I used to watch Carl Sagan's documentaries on this, and it is a fascinating subject indeed. :) Since u've chosen the name "medicguy", I am presuming u r from medical profession. So can I ask ur a simple question? Would our physiological systems be able to withstand that kind of speed? We already know that astronauts have to be conditioned to withstand such weightlessness, but there would be more of such things, wouldn't they? I am asking u because I can't ask Carl Sagan. :) Thanx in advance. :)

lol finally someone to share this with... Lemme thank you first for giving me this opportunity because i love this very concept of time travelling... it's just so fascinating :) i am still a medical student but had a handsome share of my knowledge dealing with this physical aspect of space contiuum Ok, when i was back in school doing my physics, one of my professors told me that if you happen to travel at the speed of light, nothing would change. In fact, the time for you would slow down and you won't seem to age. For instance, let's say we have mastered time travel and we decide to go to another galaxy ten light years away. So you sit in a ship (assuming that it can travel at speed of light) and you fire the engine.... for you the time will hold still but everyone back home, will be aging... so when you eventually decide to come back home... you would be ageless and perhaps, all you know about, your friends, families, everyone, would have been aged.... maybe it would be a whole different world into the future since time for earth won't be arrested or stopped so in a nutshell, once you actually achieve that sort of blazing speed, you become one with it. It's similar to like traveling in a plane or a car, speeds are very high but since we travel in momentum with the vessel itself, i believe (my opinion) our body should not face any sort of mishap!

I understood this fact during that time. by this way we can see some time the past. but how it is possible to see the future. I dont think in this way it is possible to see the future. One more thing we can get the light of the stars but how to get the light reflected by billions of objects on earth. And even one more thing is that even if it is ever possible to see the incident we cant alter any thing there or involve there.

I think..it is only in ancient story..or we seen in many movies...by time machine.. i don't reject this probability..that in future...we may be travel in time by time machine.. because time to time..technology blooming up.. and many new things discovered by scientist.. so it's possibility to travelling in time..in future...

Time travel is only theory.I don't think we can make it.
