    The video doesn’t mention the sun. Could an antimatter sun shine?

      In fact, yes. Photons don’t have a charge, so anti-photons would illuminate the Earth all the same. The issue, as the video points out, will come from too much energy hitting the Earth’s surface, not too little.

        in fact so far as i can tell, there wouldn’t be anti-photons, they’d just be normal photons

          Yep, anti-photons are just photons. They are their own counterpart.
