39 Entropy: Boltzman right, Planck wrong 125 Space is the lowest energy state for particles: that's how two oppositely charged particles can be generated out of nothing, the empty position is a hole with the opposite charge of what left it. -Matter/Antimatter comes from E=+-mc^2 since E^2=m^2c^4+p^2c^2 130 Elements heavier than iron are made in supernovae. 171 Measuring which hole an electron goes through in a dual slit experiment makes the distribution act as if they were particles, not waves anymore. -That is what makes you think of the Copenhagen Interpretation 190 A photon is its own antiparticle because time has no meaning at the speed of light by relativity and because antiparticles are said to travel backwards in time 229 You can't send information with photonic(/electron) action at a distance because the initial state of polarity or spin is random and unknown, and making a measurement changes the state of both, in effect re-randomizing, so there is no way to know whether it has changed or not - it is essentially trying to extract information from the difference of two random patterns, which is meaningless. 230 With just one particle in the universe, inertia doesn't make sense.
