Discussion Overview

The discussion revolves around the concept of anti-particles and their proposed relationship with time, specifically the idea that anti-particles may be particles that move backward in time. Participants explore theoretical implications, mathematical similarities, and the validity of this notion, referencing John Wheeler's postulates.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants question whether anti-particles can be considered as particles moving back in time, referencing John Wheeler's arguments.
  • Others assert that while there are mathematical similarities in some models, the idea of anti-particles moving back in time is not accurate.
  • One participant expresses disappointment at the rejection of the time-travel concept, indicating an emotional investment in the idea.
  • Another participant mentions the practical applications of anti-particles, such as positrons in PET scans, arguing against the feasibility of them originating from the future.
  • There are humorous exchanges regarding the term "anti-time," with some participants suggesting it was intended as a joke.
  • A later reply references the one-electron universe concept, suggesting that the idea has historical roots in theoretical physics.
  • Some participants express confusion or skepticism about the validity of the claims made regarding anti-particles and time.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the relationship between anti-particles and time. There are competing views, with some affirming the idea as a postulate and others rejecting it as incorrect.

Contextual Notes

The discussion includes speculative ideas and references to historical theories, but lacks definitive conclusions or resolutions regarding the nature of anti-particles and their temporal properties.

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..
