## Homework Statement

*Use relativistic equations and γ to demonstrate the following:*

b) Light travels through space but not in time

b) Light travels through space but not in time

## Homework Equations

Lorentz factor γ = 1 / √(1 - [v/c]^2)

Time dilation t = γ t°

Length contraction L = γ L°

Mass relativity m = γ m°

E = m c^2

## The Attempt at a Solution

To be honest, I'm not exactly sure how to approach this. I don't quite understand the concept behind what the question is really asking for. Furthermore, I don't know how I can use these equations to prove that light does not travel through time.
