Ok sorry for vanishing for abt half day. Am back.
Abt time travel.. basic thing is time is not a thing or matter which u can speed up or slow down.
Time as 4th dimension is is for measurement and record purpose, it does not mean that u can go foreward or backward in that dimension.
Time comes from inifinity and goes to infinity. So when u say u can go in future or past...does it mean u can go beyond infinity in both direction?? Does not sound right?
Sameway, science says u cant go faster than light. Light is matter, I have no idea, even if say u can go equal or faster than light, how does that even make any relation to speed?
If you say ur speed is now 2*c meters per second.. but now what is your second?? Is your new second now actually half a second?
So overall, these are just hypothesis. There are claims but have unexplained counter claims as well.
@saarth: Abt time synchronization in space running out of sync. Can you send me link?
Here is link from my side: IEEE Xplore - One-Way Time Synchronization via Geostationary Satellites at UHF
It explains why time goes out of sync and why daily adjustments are needed
AS like any dimension u can go forward or backward in it. It happens all the time. To understand it you have to understand a small but complicated thing called Frame of reference. Yes going to past has been a little problematic but going to future is very easy. All u need is acceleration.
ok here comes the prove right from text books....
there is eqn of time dilation derived in special theory of relativity
that
here v is ur velocity, hence if u go to 2c the denominator turns negative and square root produces a complex root hence the y(contraction factor)
becomes absurd.
But if the value is less than c, any value like 0.01c to 0.99c, a real value comes up which is the time contraction factor. obviously when u approach c the factor tends to infinity and hence time freezes.
This is the very base of time travel theoretically. As said by @saarth satellite time sync problems occur because of this eqn. In simple words it is in future wrt to us.
Now a layman might say then if it is in future why it does not vanish? the answer is why would it vanish, it is just at another frame of reference wrt to us and has traversed less time than us.
By the way all of u are ending up trying to prove Einstein wrong !!

just got a stupid link of some stupid scientists....
The Big Question: Is time travel possible, and is there any chance that it will ever take place? - Science, News - The Independent
some stupid excerpts.....
"Time travel into the future is absolutely possible, in fact time passes at a different rate in orbit than it does on the ground, and this has to be taken into consideration in order for satellite navigation systems to work. But time travel into the past, although technically allowed in Einstein's theory, will in the opinion of most physicists be ruled out when, and if, we develop a better understanding of the fundamental laws of physics – and that's what the LHC is all about.
