Time symmetry requires that the laws of nature operate the same when time goes either forward or backwards.
https://en.wikipedia.org/wiki/Time_translation_symmetry To the best of my knowledge, most physicists don't believe that antimatter is *actually* matter moving backwards in time. It's not even entirely clear what would it really mean to move backwards in time, from the popular viewpoint. If I'm remembering correctly, this idea all comes from a story that probably originated with Richard Feynman. At the time, one of the big puzzles of physics was why all instances of a particular elementary particle (all electrons, for example) are apparently identical. Feynman had a very hand-wavy idea that all electrons could in fact be the same electron, just bouncing back and forth between the beginning of time and the end. As far as I know, that idea never developed into anything mathematically grounded, but it did inspire Feynman and others to calculate what the properties of an electron moving backwards in time would be, in a certain precise sense that emerges from quantum field theory. What they came up with was a particle that matched the known properties of the positron. Just to give you a rough idea of what it means for a particle to "move backwards in time" in the technical sense: in quantum field theory, particles carry with them amounts of various conserved quantities as they move. These quantities may include energy, momentum, electric charge, "flavor," and others. As the particles move, these conserved quantities produce "currents," which have a direction based on the motion and sign of the conserved quantity. If you apply the time reversal operator (which is a purely mathematical concept, not something that actually reverses time), you reverse the direction of the current flow, which is equivalent to reversing the sign of the conserved quantity, thus (roughly speaking) turning the particle into its antiparticle. For example, consider electric current: it arises from the movement of electric charge, and the direction of the current is a product of the direction of motion of the charge and the sign of the charge. Positive charge moving left is equivalent to negative charge moving right. If you have a current of electrons moving to the right, and you apply the time reversal operator, it converts the rightward velocity to leftward velocity. But you would get the exact same result by instead converting the electrons into positrons and letting them continue to move to the right; either way, you wind up with the net positive charge flow moving to the right. By the way, optional reading if you're interested: there is a very basic (though hard to prove) theorem in quantum field theory, the TCP theorem, that says that if you apply the three operations of time reversal, charge conjugation (switch particles and antiparticles), and parity inversion (mirroring space), the result should be exactly equivalent to what you started with. We know from experimental data that, under certain exotic circumstances, the combination of charge conjugation and parity inversion does *not* leave all physical processes unchanged, which means that the same must be true of time reversal: *physics is* not *time-reversal invariant*. Of course, since we can't *actually* reverse time, we can't test in exactly what manner this is true. The SPP can be compared to the electron in terms of time symmetry breaking into a positron. The SPP is not LENR active until it has been converted to its antiparticle by a time reversal operator. That operator is the KERR effect that changes the rotation of photons inside the whispering gallery wave. The purpose of the LENR stimulus is to change the nature of the SPP into its LENR active form.
