# Warp Speed and Relativity

The theory of relativity states that as an object travels with velocity v, its rest mass $m_0$ changes to a mass m given by the formula $m=\frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}}$ where c is the speed of light.
Warp speed is defined by the equation $v=w^3 c$. If an object’s mass is twice its rest mass, what warp is it travelling at?
