The discussion centers on the concept of antiparticles and their relationship to time, specifically whether they move backward in time. While John Wheeler proposed ideas related to this notion, the consensus is that antiparticles do not actually move back in time; rather, there are only mathematical similarities in certain models. The conversation highlights the distinction between hypothetical ideas and established scientific understanding, noting that while antiparticles like positrons have practical applications, they do not originate from the future. Humor is also present in the discussion, with references to "anti-time" as a playful concept. Ultimately, the idea of antiparticles moving back in time is dismissed as incorrect.

Anti-particle is particle that moves back in time ? Jonh Wheeler has an argument about it ?
Is this really true ?
How this works ?
Thanks

No it is not. Mathematically there are some similarities in some models, but that is all.

I am sad :( I didnt expect this answer...

There are a great many "hypothetical ideas" that get lobbed around in science. Almost none of them get beyond the hypothetical stage, but they often attract the attention of amateurs and crackpots and, because many of these ideas sound really cool, they tend to get shared more than the mainstream models and ideas.
 
We can make or collect some kinds of antiparticles such as positrons which now have routine applications such as PET scans in hospitals.
This is obviously not possible if the positrons used have to come from the future, after then scan has been done.

An anti-particle always move forward in anti-time....:ok:

I expect that was a joke on OCR's part.

Yes, however, the explanation only exist in the future, but I can give you a preview.... :oldsmile:

This part is really true, Arman777... it was a postulate, proposed by John Wheeler to Richard Feynman, alluding to the one-electron universe.... :oldcool:

So... no need to be sad... :ok:

I heard that.But ita not a correct idea..
