"Though in some cases the particle and anti-particle are identical. That’s the case for example for the photon, which has no electric charge."

That's interesting. I was not aware that the photon had a degenerate state in this manner.

Mass, charge, spin are the basic properties of elementary particles in the Standard Model. I used to look at this poster[0] (now missing Higgs boson) but the image(svg)[1] on the Wikipedia page for Standard Model is better organized.

From popular science news, it seems like the explosion of creation would have energy concert to matter and antimatter in equal parts.

But instead, for every 10 000 000 000 anti particles there were 10 000 000 001 particles… cool!
