Does special relativity allow anything to travel faster than light explain?

Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s. This speed limit makes it unlikely that humans will ever be able to send spacecraft to explore beyond our local area of the Milky Way.

Does relativity affect speed of light?

In special relativity, the speed of light is constant when measured in any inertial frame. In general relativity, the appropriate generalisation is that the speed of light is constant in any freely falling reference frame (in a region small enough that tidal effects can be neglected).

Why the theory of relativity implies that it is impossible to travel faster than the speed of light?

Relativity does forbid ordinary matter from ever reaching the speed of light, because it would require infinite energy. Named “tachyons” by physicists in the 1960s, these subatomic speedsters would actually need an infinite amount of energy to slow down to the crawl of light-speed.

What is the fastest we can travel in space?

For centuries, physicists thought there was no limit to how fast an object could travel. But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second).

Who proved that Tachyon is faster than light?
