Please read on this website:

http://en.wikipedia.org/wiki/Faster-than-light

So,what does it mean-does it mean we can start to hope for travelling faster than light?

I also found,what some others wrote about this,from other websites:

Posted by Cangas:"We must remember this: Special Relativity was based on a postulate ( just another word for "unproven theory" ) that lightspeed is the same for all observers, which strongly implies that lightspeed is the maximum speed possible. SR does not PROVE c is maximal. It ASSUMES it.

In actual practice, particle accelerators have driven matter to speeds barely under c, and it does seem to be impossible to reach or exceed c. I have read that electrons have reached 10 mph less than c.

On the other hand, particles have been observed to execute quantum tunneling exceeding c. Entangled particles have been observed to reportedly interact exceeding c. Atomic electrons are said to instantaneously jump orbits when emitting or absorbing a photon. Although the subject is highly controversial, a contingent claims that gravity ( not gravitational waves ) must propagate at much over c.

When devising his famous set of equations, Maxwell started with standard wave mathematics and discovered that electromagetic disturbance should move through space at a speed exactly depending upon the electric permitivity and magnetic permeability of vacuum. A puzzling question is why anything else, charged particles, neutral matter, gravity, so on, would be obedient to the electromagnetic quality of space?"

Any thoughts?
