Question: do nuclei make up everything?

James Smallcombe answered on 25 Sep 2020:

Yes, almost.
They make up everything we can see or touch: people, buildings, planets, stars.
We can also say these are made of atoms, but this just means nuclei with electrons stuck to them, the electrons are all identical its the nuclei that change and make different materials.

There are other particles that exist but these are usually just flying around invisibly, they don’t ever make up solid stuff that you can actually see and use.
