Predictions for antimatter are weird

Click For Summary
SUMMARY

This discussion centers on the nature of antimatter, specifically questioning whether it can be classified as time-reversed negative matter. Participants argue that while antimatter behaves like ordinary matter electromagnetically, it exhibits unique gravitational properties where like masses attract and unlike masses repel. The conversation highlights the potential for a symmetry between electromagnetic forces and gravitation, although it clarifies that the representation of antiparticles in Feynman diagrams does not imply they possess negative mass. The thread was ultimately closed due to forum rules against personal theories and non-mainstream science.

PREREQUISITES
  • Understanding of electromagnetic forces and gravitation
  • Familiarity with Feynman diagrams and particle physics
  • Knowledge of antimatter properties and behavior
  • Basic grasp of Newtonian physics
NEXT STEPS
  • Research the implications of antimatter in gravitational theories
  • Explore the role of Feynman diagrams in particle physics
  • Investigate the concept of negative mass in theoretical physics
  • Study the relationship between electromagnetic forces and gravitation
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the properties and implications of antimatter in modern science.

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.
