[LessDumbness:] Universe shouldn’t exist. No difference between matter and anti-matter.

Universe shouldn’t exist, CERN physicists conclude
A super-precise measurement shows proton and antiproton have identical magnetic properties, writes Cathal O’Connell.
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, it’s 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 CERN’s Baryon–Antibaryon Symmetry Experiment (BASE) collaboration. “An asymmetry must exist here somewhere but we simply do not understand where the difference is.”

Antimatter is notoriously unstable – any contact with regular matter and it annihilates in a burst of pure energy that is the most efficient reaction known to physics. That’s why it was chosen as the fuel to power the starship Enterprise in Star Trek.

The standard model predicts the Big Bang should have produced equal amounts of matter and antimatter – but that’s a combustive mixture that would have annihilated itself, leaving nothing behind to make galaxies or planets or people.

To explain the mystery, physicists have been playing spot the difference between matter and antimatter – searching for some discrepancy that might explain why matter came to dominate.

So far they’ve performed extremely precise measurements for all sort of properties: mass, electric charge and so on, but no difference has yet been found.

Laser excites antimatter atoms for first time
Antihydrogen, trapped in a vacuum chamber, acts just like normal hydrogen when bathed in light. Cathal O'Connell reports.

For the first time, physicists probed an atom of antimatter with laser light – and found no detectable difference between the "excitement" of a hydrogen atom and its antimatter twin, antihydrogen.

IMHO, this looks like a new fountain for research grants. pirat

So, basically the whole Standard Model theory is proven wrong by experiments and must be discarded but the title says “the universe shouldn’t exist”, as if it’s a joke.

This is science:
The theory says that the Bib Bang produced an equal amount of matter and anti matter; experiments show that matter and anti matter always annihilate each other; theory is wrong and must be discarded.

This is today’s physics religion add-on:
Fund any number of experiments to find a difference between matter and anti matter so we can change the theory.

But I ask myself why? If they fund other experiments to make real scientific discoveries and spend the same amount of money, what’s the difference? They’d be having the same salaries...
