Thanks to a NASA physicist, the notion of warp speed might just travel out of sci-fi and into the real world. NASA's Harold White has been working since 2010 to develop a warp drive that will allow spacecraft to travel at speeds faster than light -- 186,000 miles per second.

So, simply going faster than light does not inherently lead to backwards time travel. Very specific conditions must be met—and, of course, the speed of light remains the maximum speed of anything with mass.

However, assuming that it is there, it is located 4.37 light-years from Earth. So traveling at light speed, it would only take a little more than 4 years to get there.

According to science nothing is faster than light and it is true technically as thoughts are the result of small sparks of electricity between nurons which is much slower than the speed of light. So we can say that light is faster than though.

“There is no real practical limit to how fast we can travel, other than the speed of light,” says Bray. Light zips along at about a billion kilometres per hour. ... Therefore, humans should – in theory – be able to travel at rates just short of the “Universe's speed limit”: the speed of light.

Do gravitational waves travel faster than light? No, gravitational waves also travel at the speed of light in vacuum. However, the interstellar medium is not perfectly empty but filled with plasmas which slow electromagnetic waves (light, radio) down by a factor n, the refractive index.

Tachyons. In special relativity, it is impossible to accelerate an object to the speed of light, or for a massive object to move at the speed of light. However, it might be possible for an object to exist which always moves faster than light.

Yes, wind can travel faster than the speed of sound. ... The speed of sound is not a fundamental speed like the speed of light is. The speed of sound just describes how fast a mechanical wave travels through a material. Different materials have different speeds of sound.

['Faster-than-light (also superluminal or FTL) communications and travel are the conjectural propagation of information or matter faster than the speed of light.', 'The special theory of relativity implies that only particles with zero rest mass may travel at the speed of light.']

There is yet another possible way in which faster-than-light travel is technically possible: rifts in space-time itself that allow a voyager to escape the rules of normal travel.

As dark energy causes the universe to expand ever-faster, it may spur some very distant galaxies to apparently move faster than the speed of light. ... Over and over (and over and over) we're told the supreme iron law of the universe: Nothing — absolutely nothing — can go faster than the speed of light.

An Italian experiment has unveiled evidence that fundamental particles known as neutrinos can travel faster than light.

The fact is we'll never be able to travel beyond the speed of light, at least based on our current understanding of established physics. ... The LHC, the largest and highest-energy particle accelerator we have, boosts protons as close to the speed of light as we can get, but they never quite hit the mark.

The FTL Drive is the propulsion system used by human and Cylon ships to achieve faster-than-light travel through space. Prior to a jump, the drive is "spooled up" and then the ship "jumps" to another point in space.

The answer lies in tachyons. These are particles with imaginary mass that can be thought of as travelling backwards in time. They move faster than light, and slowing down to the speed of light would be as impossible for them as it is for us to accelerate to light speed.

Simply put, the speed of light (c) is the fastest velocity at which an object can travel in a vacuum. As an object moves, its mass also increases. Near the speed of light, the mass is so high that it reaches infinity, and would require infinite energy to move it, thus capping how fast an object can move.

So, here's your answer! We can travel faster than time by just approaching close to the speed of light. ... But, time dilates negligibly for every body “not at rest” with low velocities (like we achieve in our daily life) with respect to another body at rest in the same frame of reference.
