and an anti electron orbiting it.

It's even been hypothesized that you could theoretically have entire planets made up of antimatter with exactly the same chemistry as our planet, just with the antimatter versions.

Although as far as we know, no such things exist, because the very early universe seemed to have the a huge asymmetry between matter and antimatter, and almost all of the antimatter was eliminated.

When an electron and a positron come close enough together, they'll eliminate, uh they'll cancel each other out effectively and and produce

A photon.

The same thing happens with other types of matter and antimatter as well.

So early in the universe, it's thought that there was at some point equal matter and antimatter.

But most of the antimatter was eliminated, leaving a small residual left over, which is the matter.

But we don't know where this initial asymmetry came from.

That's still an open question.

So fr theoretically from the standard model, there could just be as much matter and antimatter around as each other, they could be equal, uh, because all of the f forces work the same as far as you know, with matter and antimatter.

Uh but as it turns out, the universe currently is filled almost entirely with matter, and w we don't entirely know why this is the case.

So at this point, I've introduced all of the particles that are in the standard model.

So there are 24 different fermions.

That's a spin half particle and think matter particles.

So there are six quarks, six leptons, and then the corresponding anti quarks and anti leptons.

There are then three different sort of families of gauge bosons, each corresponding to a different fundamental force.

There's the gluons for the strong nuclear force.

photon for the electromagnetic force, and the W and Z bosons for the weak nuclear force.

bosons have a spin of or these bosons I should say have a spin of one and they can be thought of as energy as opposed to the matter that constitutes the fermions.
