Back in my youth, after the Internet became common but before Wikipedia, I tried to discover the answer to this and came away disappointed again and again. Every article I could find simply stated "because light scattering", and barely much more.

How does scattering work? Why does light scatter? _What does scattering even mean in the context of light?_

Yes! This is exactly why I wrote this article :)

Any other questions give you the same disappointment?

How can light "bounce off" something if it doesn't have mass?
