4-vectors

Using index notation, the time and space coordinates can be combined into a single "4-vector" [math]x^{\mu},\ \mu=0,\ 1,\ 2,\ 3[/math], that has units of length, i.e. ct is a distance.

[math]\begin{bmatrix} x_0 \\ x_1 \\ x_2 \\ x_3 \end{bmatrix}= \begin{bmatrix} ct \\ x \\ y \\ z \end{bmatrix}[/math]
