I know we're all happily geeking out over the new findings at the LHC and elsewhere. You know, since we like to exist, and stuff.

Quote:
Physicists at the Fermi National Accelerator Laboratory are reporting that they have discovered a new clue that could help unravel one of the biggest mysteries of cosmology: why the universe is composed of matter and not its evil-twin opposite, antimatter. If confirmed, the finding portends fundamental discoveries at the new Large Hadron Collider outside Geneva, as well as a possible explanation for our own existence.

In a mathematically perfect universe, we would be less than dead; we would never have existed. According to the basic precepts of Einsteinian relativity and quantum mechanics, equal amounts of matter and antimatter should have been created in the Big Bang and then immediately annihilated each other in a blaze of lethal energy, leaving a big fat goose egg with which to make stars, galaxies and us. And yet we exist, and physicists (among others) would dearly like to know why.


It's a good read. Fat muons! Indecisive B-mesons, the Hamlets of subatomic particles! Thrills, chills, spills and adventure.

Also, and this impressed me quite a bit... has anyone else noticed that as soon as you scroll to the last line in the article, the little slide-in window at the bottom right appears with the next suggested article? Very nice work, NY Times.

As for the article,

Quote:
As it happens, the mesons, created in the proton-antiproton collisions, seem to go from their antimatter state to their matter state more rapidly than they go the other way around, leading to an eventual preponderance of matter over antimatter of about 1 percent, when they decay to muons.


Makes perfect sense from a layman's perspective. Particles that change to matter more quickly than they do antimatter will inevitably spend more time existing as matter, resulting in an imbalance, and eventually, us. Interesting stuff.

Polonius and Gertrude nearly had him sussed:

Polonius:
Your noble son is mad:
Mad call I it, for to define true madness,
What is't but to be nothing else but mad?
But let that go.

Queen:
More matter with less art.

Polonius:
Madam, I swear I use no art at all
That he's mad, 'tis true, 'tis true 'tis pity,
And pity 'tis 'tis true—a foolish figure,
But farewell it, for I will use no art.

Score one for the local boys over at Fermi!

It's a shame the way we dropped the ball and allowed the new collider to go over to Europe.

I'm sure we could eke a few billion out of the unspent bailout funds to build a bigger, better, more bad-*** collider here now.

Go for the space laser instead imo.

You guys recall the Superconducting Supercollider (SSC) cancelled in 1993 (after 15 miles of tunnels were dug)?

It would have had about 3x the energy of the LHC.

Also: very cool article Samira! I actually didn't realize this was not well established. When I finished undergrad around the mid-1990's there was a shiny new theory which purported to explain matter–antimatter asymmetry and literally until 10 minuets ago I would have told you that. However, turns out that didn't work out. The most recent review article on the topic from 2003 begins with:

"Although the origin of matter-antimatter asymmetry remains unknown, continuing advances in theory and improved experimental limits have ruled out some scenarios for baryogenesis, for example, sphaleron baryogenesis at the electroweak phase transition in the Standard Model. At the same time, the success of cosmological inflation and the prospects for discovering supersymmetry at the Large Hadron Collider have put some other models in sharper focus. "

Yup. Thanks, Bill Clinton.

Clinton tried to prevent the cancellation, actually. Congress decided it was too expensive (and of course its cost had ballooned, so they had a point).

I know, but I had an opportunity to lambaste slick Willy, so I took it. Take your sense of Recent Perspective and back off.

I should take the kid by Fermi Lab now that he's old enough to understand it. Also, they have buffalo wandering around there.

I spent some time at Stanford's linear accelerator when I was in my teens. My dad was on the realignment project after the '89 quake. 2 miles long with tolerances of 3 microns (3 millionths of a meter). Interesting place.

As long as it was misaligned anyway, they should have filled the tunnel with water and shot you through it before they got started.

I interned at Fermi one summer while in college. The first week I was there a cat had gotten lost in the tunnel and died and it smelled awful. Very interesting place.

If you think dead cats are interesting, let me show you some alleys you should find enthralling...

I just found the phrase "evil-twin" to describe antimatter amusing, as if somehow we were lucky that we aren't made up of antimatter. Not to be obvious or anything, but if the universe had decided to give antimatter the edge instead of matter, we'd just have switched the labels. It's not like we'd be able to tell the difference...
