Don’t waves need a medium to travel through? Isn’t space just essentially empty? I know they’re electromagnetic waves, but what does that mean essentially?
Edit: Thanks for the response guys. From your response I’ve realised there’s no way to explain to a 5 year old how light works!

It doesn’t need a medium to travel, it’s not actually a wave as others have said. However, you might be interested to know that at one point it was theorized that light traveled through the “ether”. The experiment to disprove this is pretty interesting: https://en.m.wikipedia.org/wiki/Michelson%E2%80%93Morley_experiment .
