Do antiparticles travel backwards time?

In terms of the known laws of physics, antimatter behaves mathematically equivalent to normal matter simply traveling backwards in time. Effectively antimatter particles are indistinguishable from normal matter traveling backwards in time on a particle by particle basis.

Do positrons go back in time?

An electron travelling backwards in time is what we call a positron. In the diagram, the electron travelling backwards in time interacts with some other light energy and starts travelling forwards in time again.

Are there particles that move backwards in time?

Hypothetical superluminal particles called tachyons have a spacelike trajectory, and thus can appear to move backward in time, according to an observer in a conventional reference frame.

Does antimatter have reverse entropy?

Not that it’s impossible, just extremely unlikely. Antimatter is matter going backwards through time.

Is there still antimatter?

For the past 50 years and more, laboratories like CERN have routinely produced antiparticles, and in 1995 CERN became the first laboratory to create anti-atoms artificially. But no one has ever produced antimatter without also obtaining the corresponding matter particles.

Does the future determine the past?

THE future can affect the past, according to a bizarre new theory which adds even more weirdness to the strange world of quantum mechanics. With distance between the particles not being a factor, researchers have now set out to discover whether time plays a part in quantum mechanics.

Can a positive energy particle move backwards in time?

However, it is always possible to interpret a positive energy particle moving forward in time as a negative energy antiparticle moving backward in time. Or conversely, a positive energy antiparticle moving forward in time can be interpreted as a negative energy particle moving backward in time.

How does an anti-particle behave in the past?

In physics, whenever you’re trying to figure out how an anti-particle will behave in a situation you can always reverse time and consider how a normal particle traveling into the past would act. “Anti-matter acts like matter traveling backward in time”.

Do physicists believe that antimatter is matter moving backwards in time?

To the best of my knowledge, most physicists don’t believe that antimatter is actually matter moving backwards in time. It’s not even entirely clear what would it really mean to move backwards in time, from the popular viewpoint. If I’m remembering correctly, this idea all comes from a story that probably originated with Richard Feynman.

Do interactions between particles play forward or backwards?

Interactions between individual particles play forward just as well as they play backwards, including particle creation and annihilation. Left: An electron and a positron annihilate producing two photons.
