Cool. I don’t know if that aligns the the current theory and frankly, don’t care enough to research it.

But that doesn’t disprove my statement. Unless all matter juices itself into energy, heat will exist. heat is a property of matter unless said matter is at -273 C (which seems impossible that that is the temperature for the universe to settle on)

But… I’m not a theoretical physicist and you probably aren’t one either. So we are both out of our depth.
