Frequently Asked Questions
What is the Lorentz factor?
The Lorentz factor, written gamma, measures how much time, length, and mass change at relativistic speeds. It equals one divided by the square root of one minus the velocity squared over the speed of light squared, and it grows without bound as speed approaches light speed.
Why must velocity stay below 100 percent of light speed?
At the speed of light the Lorentz factor would require dividing by zero and becomes infinite, so no object with mass can reach or exceed it. The calculator therefore only accepts velocities below 100 percent.
