Predictions for antimatter are weird

  • #1
Is antimatter time-reversed negative matter?
If so, then it would behave like ordinary matter electromagnetically BUT Newton's grav would yield like mass charges attract and unlike masses repel. Ie, a combination of antimatter and matter does not make a diametric drive due to the time inversion of the antimatter.
It would make an elegant symmetry between the em forces and gravitation.

You may have read something somewhere about antiparticles being normal particles moving backwards in time? If so, that's not really what's going on. It is true that antiparticles are represented in Feynman diagrams that way, but that's a just a convenience in the calculation, and it does not imply that they have negative mass.

Because Physics Forums rules prohibit discussion of personal theories and non-mainstream science, this thread is closed.
