Okay, so I see this pizza chart a lot on the web that points physical matter with mass making up 4.6% of all matter in the universe, followed by dark matter with 23% and dark energy with the rest. Where the heck did old fashion, normal energy go? is it not good enough to get it's own place in the pizza chart? I've seen neutrinos in some, but what about photons, all waves on the electromagnetic spectrum, heat, sound, etc.? Also...Is there dark anti matter?
