What are lorentz transformations?

Lorentz transformations are like special rules that help us understand how things look when they're moving really fast, almost as fast as light.

Imagine you're on a train that's zooming down the tracks, and your friend is standing still outside the train. To you, everything inside the train seems normal. But to your friend, things inside the train seem a little squished or stretched. That’s what Lorentz transformations explain, they show how time and space change when something is moving super fast.

Think of it like playing with blocks. If you’re standing still, your blocks look normal. But if you start running past them really fast, the blocks might seem a little shorter to you, even though they didn’t change at all! This is called length contraction.

At the same time, time also changes. Imagine you have a clock that ticks every second. When you're moving super fast, your friend outside will see your clock ticking slower, this is called time dilation.

So Lorentz transformations are like the "rules of the game" when things move really fast, they help us see how time and space act differently for people who are moving quickly compared to those who are still.
