Time Travel?

Now that we are on the topic of space and travel, here is something I came across today (via Huffington Post)..

It seems Russian cosmonaut Sergei Krikalev has spent more time in orbit around the Earth than anyone - 803 days, 9 hours and 39 minutes

And thanks to Universe Today, we know he is also the most prolific 'time' traveler - he has actually time-traveled into his own future by 0.02 seconds !!

"The calculation relies on Einstein's theories of relativity, which state that the passage of time is relative, and different, for two objects moving at different speeds or experiencing different levels of gravity.

Time dilation is a real effect, and has been demonstrated in experiments conducted first by flying highly accurate atomic clocks around the world on jet aircraft, and later by GPS satellites which have to be reprogrammed daily to counter the effect."

PS 1: how many of you seen 'Gravity'?

PS 2: how many of you like to travel in space?

PS 3: how many of you like to travel in space-time?!

Of course, I have watched 'Gravity' and loved it.. And am up for the rest of it on the list.. :)
