Why do tachyons increase in speed by decreasing in energy

Question:

Why do tachyons increase in speed by decreasing in energy?

Tachyon:

In modern physics, the tachyon is defined as the particle of imaginary mass, which travels faster than the speed of light. The energy is released when the tachyon is connected with an electric charge.

Answer and Explanation:


The expression of Lorentz invariant theory is given by.

{eq}E = \dfrac{{m{c^2}}}{{\sqrt {1 - \dfrac{{{v^2}}}{{{c^2}}}} }} {/eq}


Here,

{eq}m {/eq} is the rest mass.

{eq}v {/eq} is the speed of the tachyon.

{eq}c {/eq} is the speed of light.

{eq}E {/eq} is the energy of the particle.


The equation shows that when the speed of the tachyon is greater than the speed of light, then the energy will be imaginary, and it is also clear from the above equation that the tachyon speed is increased with a decrease in energy.


Thus, this is the reason why speed of tachyon increases with decrease in energy.
