Does antimatter moves back in time? CPT-invariance and atheism.

[joinfree]

The Standard Model of Particles demands the Charge-Parity-Time symmetry (CPT) between matter and antimatter,´so, one can conclude, that positron is of opposite electric charge, mirror-reflected, and moves back in time? The CPT-invariance was perfectly confirmed in 2017: A parts-per-billion measurement of the antiproton magnetic moment

No, the CPT-invariance is not the CPT-symmetry, The CPT-invariance holds for electron (or an other particle) only. Namely, the positively charged electron, which moves back in time, is same as the negatively charged electron, which moves forward in time. Because the motion back in time is forbidden, then the CPT-invariance is not physical, but mathematical. Therefore, how can one judge over the amount of antimatter in Beginning of Universe, looking at CPT-invariance? The Dr. Kaku'es video: Reality Rejection as result of Atheism

Appears as though you really need to convince yourself of something.

Have fun.

If time is simply the observation of cause and effect relationships, then such an observation moves in the same direction irrespective of the matter observed.

What does this thread have to do with atheism?

Posting the same thing in multiple threads doesn't make it any more correct.

I'm guessing (wildly, at that), that the argument goes something like: science doesn't have an immediate answer to a strange thing, therefore all science is false and thus BIBLE.

I've heard this point of view on many occasions and it's more than a bit baffling.

...so, one can conclude, that positron is of opposite electric charge, mirror-reflected, and moves back in time?

Not really; it's more a way of considering interactions in Feynman diagrams, meaning (roughly) that you can use the same diagram for electron or positron interactions by reversing the time direction.

The CPT-invariance holds for electron (or an other particle) only. Namely, the positively charged electron, which moves back in time, is same as the negatively charged electron, which moves forward in time. Because the motion back in time is forbidden, then the CPT-invariance is not physical, but mathematical.

It comes to the same thing - CPT-invariance doesn't require movement back in time, only that a positron with mirror spin and direction (to an electron) must be indistinguishable from the electron moving back in time.

This text-book way of thinking has led Scientists into the conclusion, that there is no Universe (see the link with Dr. Kaku video). Thus, new thoughts are needed, one of these is in my thread.

God did it. End of discussion and study.

There may be something to it. I went to service training for medical PET scanners. A PET scanner detects antimatter particles call positrons. The physicist who taught one of the classes said a positron is an electron with its arrow of time reversed. After being ejected from the nucleus the positron travels on average only a few millimeters before its kinetic energy is expended. Then it combines with a random electron, is annihilated and converts pure energy in the form of two 511 Kev photons. What is perhaps kind of interesting is that these photons travel in exact opposite directions. It is actually these photon pairs moving in opposite directions that the PET scanner detects.

Where is all the anti-matter is a curious question. Perhaps at the Big Bang matter and anti-matter went in opposite directions in space and perhaps even time. It is mind boggling and I'm glad I don't have to try to figure it out for a living.

Not that there is no universe - obviously. But that we don't yet understand its early moments well enough.

Even if matter and antimatter had annihilated completely, there would still be a universe - but one without matter.

Science runs on a popularity model. More is more.

Because the motion back in time is forbidden, then the CPT-invariance is not physical, but mathematical.

Not forbidden, just not a viable option.
