What are Tachyons? Tachyons are particles that travel faster than the speed of light in a vacuum. Imagine an object that, instead of moving in the normal forward motion, appears to move backward in time. This is the concept of the tachyon, theorized by American physicist Gerald Feinberg in 1967.Tachyons are believed to have the ability to travel at speeds faster than that of light. They are never at rest and possess no mass. According to Einstein’s Theory of Special Relativity, nothing can outpace light in a vacuum, but tachyons would be able to go faster than light, so they can theoretically travel backward in time.Normally, when we think of particles traveling faster than the speed of light, we envision them as particles with a positive speed. Tachyons have a different type of speed, referred to as imaginary speed, which results in them traveling backward in time. This means that events appear to happen before causes.Tachyons can also exhibit some fascinating properties, such as the ability to maintain a constant velocity throughout space-time and an infinite acceleration when given enough charge. In comparison to a normal particle, the tachyons speed increases as it moves closer to any point in
