Antiparticles moving opposite direction in time?

[rolnor]

TL;DR Summary

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 it correct?

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

Thread closed.

As a follow-up, the underlying physics that leads some pop science sources to talk about antiparticles "going backwards in time" is discussed in this previous PF thread:
