Hey, if they are faster than the speed of light, they can do anything. They can most probably travel into the future and bring us back the next winning lotto numbers

As long as something new found to be faster, who cares if he would be happy or not.

My cat cares!

"Extraordinary claims require extraordinary evidence."

I am betting they got it wrong - otherwise it will be a crowded Nobel Prize ceremony next year (obviously not a scientific argument).

this is  a self-contradiction

your cat is a perfect match with Einstein, a Nobel cat

Yeah, I thought about the time too.  You must hear of the Twin paradox?http://en.wikipedia.org/wiki/Twin_paradox
Although I'm not sure I fully understand that, I'm always wondering what would happen when the twin get together again after a faster-than-light travel, a man v.s. his "baby" brother?

I'm really curious, can the backwards-time work in the view of the physicist?

I am very rusty on my physics. It seems the older you get, the less you understand. If I remember correctly (others please correct me):
1. it is not a true paradox, because the twin on the rocket will feel the acceleration and deceleration, but not the twin remaining on earth;
2. using general relativity, physicists can calculate there is an age difference.

All this is explained much better in Wikipedia.

Of course, if one of the twins can travel faster than light - where do you start, special relativity would be useless?

Yeap, I agree all of that.

I'm more interested in the operability of the backwards-time.

I guess some physicists would get nuts when they try to take it seriously.

Nuts, it certainly drives me nuts when I think about traveling backward in time, or time traveling through worm holes etc.
