and we can't interact with it. Matter particles, game mass at this point, the observable universe exists as a sphere of about 300 light seconds across. That's about 0.6 astronauts, that's the distance of sun that's away from it. So, about more than half of that. And at QED, that's the quantum-electro dynamics. I tend to minus 15 seconds, the exponent minus 15 seconds. Quark-Won plasma, a particle, combined into a hadron, mostly protons, neutrons, and drons. Proton and neutrons are considered composite particles are made up of quarks and gluons, just drop in. And neutrino decoupling happened just after that. And these, this is where they stopped the electron. They stopped interacting with regular matter, baryonic matter.
