Matter and Antimatter Symmetry - John Doyle

Physicist David Southwood from University of Cambridge on how the magnetic field of Earth causes natural losses of spacecraft, the aurorae and why it’s important to study plasma physics.

Perfect

[@jklappenbach]

What if we *are* made of antimatter, and what we call antimatter is the real stuff?

[@dennismoore2752]

Ok, why are they looking for time-reversal? Why do i get the impression, they try to explain matter of fact with even more convoluted means?

[@doodelay]

Kindly, because you don't know what you're talking about and they do. So you don't know what's matter of fact or how to solve the problem they're trying to solve

[@darkzeda]

is it possible that during inhalation of matter and antimatter we see only the photons produced by the matter while the antimatter photons who have opposite charge and spin are sucked in by nucleus ...in other words anti matter light travels in opposite direction ,( time minus, an instant black out)......This will explain the presents of dark matter in the universe,...... You guys don't forger to give me credit for the major theory I just made up,...

Siva Sankaran time with minus sign lol

[@hasanmasbaulalitaher9705]

good idea

[@livelaughloveandmore]

Thank you so much for a brilliant theory there. :D Although the photons do not discriminate between matter and antimatter. The Standard model of Particle Physics has just fermions and bosons. To every particle in the fermion, we have a corresponding antiparticle. However, as far as experimentally proven and well discussed in the theory, photons are of only one sole type, photons. So when a particle anti-particle pair annihilates, we get just energy which corresponds to the pair and is not specific to either particle or antiparticle.

Photons are neutral so this would not work

[@ibperson7765]

We actually live in an anti-matter universe. We have misnamed the two. We can’t tell, but it’s true.

8years later: what happened?

Second this
