SUMMARY

Antiparticles do not move in the opposite direction of time, contrary to some pop-science claims. The discussion confirms that this notion is incorrect and emphasizes the importance of understanding the underlying physics. The topic is linked to previous discussions on Physics Forums, specifically regarding the nature of antiparticles and their behavior in quantum mechanics. Practical applications, such as PET scanning, do not require consideration of time-reversal effects related to positrons.

PREREQUISITES
  • Basic understanding of quantum mechanics
  • Familiarity with particle physics concepts
  • Knowledge of positron emission tomography (PET) scanning
  • Awareness of the implications of antiparticles in physics
NEXT STEPS
  • Research the principles of quantum field theory
  • Explore the concept of time symmetry in physics
  • Study the role of antiparticles in particle physics
  • Investigate the technical aspects of PET scanning and its applications
USEFUL FOR

Physicists, students of quantum mechanics, medical professionals using PET technology, and anyone interested in the implications of particle physics.

TL;DR
Does antiparticles move backwards in time
I have seen this in pop-science, is it correct? Does antiparticles move in the oppisite direction of time? Is it possible to prove this experimentaly? Does it have any practical consequenses? We use PET-scaning everyday, is there anything to consider when working with positrones connected with them moving back in time?

Which should already raise a red flag that the answer to this...

...is going to be "no". Which it is.
