What are time travel scientists called?

Answer 1

Now, don't be stupid! Nobody has actually invented time travel yet! - Or at least nobody has invented a REAL time travelling machine! (people have come up with the idea before, but it will probably never work)

Answer 2

Theoretical physicist more than likely.

As far as time travel I fear physicists have already discovered what is worth to be know. Travel towards future is in principle possible. It is sufficient to move with a speed near the light speed with respect to the starting inertial reference (the earth for one of us).

The relativistic phenomenon of time compression provoke the time to pass much slower for the traveler with respect to the persons remaining in the "fixed" reference.

When the traveler returns in the initial reference (the earth in our example) he effectively traveled towards the future.

Unfortunately, travel towards the past is effectively impossible due to the causal nature of the laws of physics. As a matter of fact, reversing the time in only one phenomenon (the travel of our traveler in this case) violate the essential law of relativity that causal order has to survive between events happening in the same point of the space. Thus it is simply impossible.

(look, I'm not going to retype his entire response but: e-mc^2 thus a particle with a negative mass will go at a negative velocity and thus backwards in time. such particles are thought to be possible (at least not counted out yet) there are also a million other ways that intelligent forces can bypass naturally unbreakable laws such as wormhole's, however improbable they may be, given infinite time and flexible enough conditions anything is possible. so go ahead and become a theoretical physicist and prove this guy wrong.)

This renders traveling to future quite unattractive: It is impossible to return from such a travel.
