The bible of particle physics is dying for an upgrade. And physicists may have just the thing: Some particles and forces might look in the mirror and not recognize themselves. That, in itself, would send the so-called Standard Model into a tailspin.
Just about all fundamental reactions between the universes subatomic particles look the same when they are flipped around in a mirror. The mirror-image, called parity, is then said to be symmetrical, or to have parity symmetry, in physics speak.
Of course, not everyone follows the rules. We know that, for instance, reactions involving the weak nuclear force, which is also weird for a whole bunch of other reasons, violates parity symmetry. So it stands to reason other forces and particles in the quantum world are also rule-breakers in this area.
Physicists have some ideas about these other hypothetical reactions that wouldn't look the same in the mirror and hence would violate parity symmetry. These strange reactions could point us toward new physics that could help us move past the Standard Model of particle physics, our current summary of all things subatomic.

(70,225 posts)in college. i liked chemistry, but physics had the best toys.
my dad loved science, and was on his way to being a doctor when the depression hit. even tho he had a full boat, he had to drop out as a junior. he had straight a's in pre-med.
broke his heart, and he tried hard to get one of his kids to go for it.
he had hope for me, and my first pass through college, that was the plan.
he taught me so much science as a little girl, that my first 2 years were pretty much a breeze.
family got in the way, and by the time i got back to school it was art school, w a stint in the building trades in between.
but i still love science, and really appreciate your posts.
sometimes they go over my head, but i always get something out of them.

I learned long ago there are people who absolutely live on different levels mentally, and I am amazed and curious, and very thankful.
Thanks for your great post.
