Can you explain Einstein's Theory of Relativity like I'm a 5 year old?

Albert Einstein revolutionized the way we view the universe by introducing us to his Theory of Relativity. Understanding it can be difficult, even for adults, but explaining it to a 5 year old?

That’s a whole other challenge! Let’s see if we can break it down in simple terms so that even a kindergartener would understand.

To make the concept easier to explain, let’s imagine two people in two different spaceships traveling near the speed of light. One person is aboard Ship A and the other is aboard Ship B. Now, let’s say both ships are moving away from each other at exactly the same speed, the speed of light!

According to Einstein's Theory of Relativity, time passes differently for each person because they are moving at different speeds relative to each other. So, while time may pass more quickly for the person aboard Ship A than for the person aboard Ship B, from their perspective time passes normally, it just passes differently for each spaceship relative to one another!

What does this mean? It means that when you look up in the night sky and see stars that are millions of light years away, those stars might actually be very close, but due to relativity they appear far away because their light has been traveling at different speeds relative to our own. The same goes with events that happened long ago; due to relativity, they appear much older than they actually are!
