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.
 

1. What is antimatter?

Antimatter is a type of matter that has the same mass as regular matter but with opposite electrical charge. For example, an antiproton has the same mass as a proton but with a negative charge.

2. How is antimatter created?

Antimatter can be created through high-energy collisions, such as those that occur in particle accelerators. It can also be produced naturally through certain radioactive decays.

3. Why are predictions for antimatter considered weird?

Predictions for antimatter are considered weird because it behaves differently than regular matter in certain situations. For example, when an antiparticle and a particle come into contact, they annihilate each other and release a large amount of energy.

4. What are some potential uses for antimatter?

Antimatter has potential uses in medical imaging, cancer treatment, and propulsion systems for spacecraft. However, it is currently very expensive and difficult to produce and store in large quantities.

5. Is there more antimatter than matter in the universe?

No, currently there is a significant imbalance between matter and antimatter in the observable universe. This is a major mystery in physics known as the baryon asymmetry problem.
