Lorentz transformation

Lorentz transformation is a type of mathematical equation that helps us to think about how things move when they are going really fast. It's like an equation for super speed! When we do the equation, it helps us understand how things look different if we were looking at them from two different points, like from two different spaceships. For example, if one spaceship was moving really fast, and we looked at the same thing from both spaceships, it would look like two different things. The Lorentz transformation helps us understand what those two different things look like.
