What if I could tell you that the entire universe was mad up of 3 things?

Ready?

The most basic “things” that make up everything we know. Protons, Neutrons and Electrons.

But wait. We don’t even have the technology to see atoms!! So how do we know if these 3 basic “things” aren’t made up of some element that we, obvouisly, cant detect, see, whatever.
