One of the great mysteries of modern physics is why antimatter did not destroy the universe at the beginning of time.
To explain it, physicists suppose there must be some difference between matter and antimatter apart from electric charge. Whatever that difference is, its not in their magnetism, it seems.
Physicists at CERN in Switzerland have made the most precise measurement ever of the magnetic moment of an anti-proton a number that measures how a particle reacts to magnetic force and found it to be exactly the same as that of the proton but with opposite sign. The work is described in Nature.
All of our observations find a complete symmetry between matter and antimatter, which is why the universe should not actually exist, says Christian Smorra, a physicist at CERNs BaryonAntibaryon Symmetry Experiment (BASE) collaboration. An asymmetry must exist here somewhere but we simply do not understand where the difference is.

there..I've solved it. Now back to lunch.

(13,485 posts)Now I can. Weird. Note the edits on that post. Several times I tried it with and without Javascript. Maybe it was a momentary chance meeting with anti-apostrophe.

(40,416 posts)There is a special circle of Hell for headline writers like that.
And particle physics, and quantum field theory in general, is all about symmetries, and broken symmetries.
I seem to remember that there was a broken symmetry recently discovered in particle/anti-particle interactions. Sorry, just cannot remember what that was.
Regardless, obviously the universe exists, so there has to be a broken symmetry somewhere.

Other than that, it does seem that the universe does exist.

The universe shouldn't exist, according to new ultra-precise measurements of anti-protons.
But the fact that I'm typing this article and you're reading it, however, suggests that we are here, so something must be awry with our understanding of the physics the universe is governed by.
The universe is the embodiment of an epic battle between matter and antimatter that occurred immediately after the Big Bang, 13.82 billion years ago. Evidently, matter won because there are galaxies, stars, planets, you, me, hamsters, long walks on sandy beaches and beer but how matter won is one of the biggest mysteries hanging over physics. [The Strangest Things in Space]
It is predicted that equal amounts of matter and antimatter were produced in the primordial universe (a basic prediction by the Standard Model of physics), but if that's the case, all matter in the universe should have been annihilated when it came into contact with its antimatter counterpart a Big Bang followed by a big disappointment.
