Did Einstein just invent time and space?
Imagine you're on a train moving at a constant speed. To you, everything inside the train seems normal. But to someone standing outside, the train and everything inside it are moving. How can both of you agree on what's happening?
The theory of relativity suggests that time and space aren't absolute; they change depending on how fast you're moving. This idea is called "spacetime."
Example
If you're on a train moving at high speed, a clock inside the train ticks slower than one outside.
Remember this
The key insight is that time and space are linked and can change based on speed, not constant.
