You can always keep going faster and faster, but as you approach the speed of light and keep gaining more and more relativistic mass, it becomes harder and harder to increase your speed.

### Can information travel faster than light?

According to Einstein's theory of relativity, No.

### Where would you end up if you could travel faster than light?

If you could travel faster than light, then you could also travel to the past. This is related to the definition of simultaneity, in the Special Theory of Relativity.If you could travel faster than light, then you could also travel to the past.

### Where does the light travel fast?

Light travels fastest in vacuum. It can never go quicker than that (this is one of the postulates of special relativity).

### Where does a photon get its speed from?

Nowhere. A photon must travel at the speed of light so it starts with that speed when it is created. This is the origin of the theory of special relativity.

### Can a lepton travel faster than the speed of light?

Leptons have mass.According to special relativity, no particle with mass can travel at or faster than the speed of light. It would take infinite energy to do so.

### Why any object cannot travell with the speed of light?

Some particles, like photons and gravitons, are believed to ALWAYS travel at the speed of light. Particles, or larger amounts of matter, that move at a slower speed can't be made to travel at the speed of light - according to the Special Theory of Relativity, that would require an infinite energy.

### According to Einstein's Special Theory of Relativity if you are moving at near light speed?

Near the speed of light:Time will go slower.Masses will increase.Distance will get reduced (in the direction of travel).Energy will be dissipated in Gravitational Waves.All of this is from the point of view of an outside observer - one that doesn't participate in the movement.

### According to Einstein's E equals mc squared... theoretically... what would happen to an object if it's velocity excelled the speed of light?

According to special relativity, nothing can travel faster than the speed of light. The formula E = mc2 does not directly show that a body cannot travel faster than the speed of light, but if it did travel that fast, its energy would be so high that its mass would also have to be very, very large.

### What is the speed that gravity travels?

Gravity is believed to travel at the speed of light. This follows from theory, especially the Special and the General Theory of Relativity; I believe there is not yet enough experimental evidence to confirm this speed.

### Why was the theory of relativity invented?

It was invented when Albert Einstein realized that Universal Gravitation was incorrect. He realized that he needed to propose a theory which would resolve this problem. When Einstein completed Special Relativity, he formulated that nothing travel faster than the speed of light. However, Newtonian Gravitation stated that Gravity was an instantaneous force, therefore this was problematic. Thus Einstein worked on General Relativity to resolve this query by introducing spacetime distortion which result in the gravitational waves that travel at the speed of light.

### Why can't anything travel at a speed faster than light?

Various reasons, most of them related to the Special Theory of Relativity. 1. To speed something up so that it even reaches the speed of light (from an initial speed that is slower than light) would require infinite energy. (However, this doesn't preclude hypothetical particles that ONLY travel faster than the speed of light.) 2. If it is were possible to travel faster than the speed of light, it would also be possible to travel to the past. This is due to the definition of "simultaneity" in the Special Theory of Relativity. If you ever read stories about time travel, you would know that time travel may result in many contradictory situations, so it seems doubtful at the least.

### If time travel was possible could you in the distant future move several light years in a space by traveling close to the speed of light and than traveling backwards through time at regular intervals?

Indeed, time travel, and travelling faster than the speed of light, are intimately related in the Special Theory of Relativity. Looking at the situation from the other side, if it were possible to travel faster than light, then from some point of view, you would be travelling backwards in time. For more details, read about the definition of "simultaneity" in the Special Theory of Relativity.Probably none of the two is possible - travelling backwards in time, and travelling faster than light.Indeed, time travel, and travelling faster than the speed of light, are intimately related in the Special Theory of Relativity.
