Atom Smashers

The United States’ largest atom smasher is smashing atoms no more.  I’m sure atoms are very happy about this, but most of the scientific community is disappointed.  In many ways, shutting down the Tevatron Particle Accelerator is like ending the space shuttle program.

The Tevatron had been in service for nearly thirty years and was responsible for many important discoveries in particle physics.  Most people never even heard of it and have no idea why this matters, but without particle physics (a.k.a. quantum mechanics) we wouldn’t have wireless communications, plastic, or most modern drugs.  We wouldn’t even understand DNA if we didn’t know how atoms and the particles inside them work.

The Tevatron cost millions of dollars to build and millions more to operate.  The Department of Energy says they could not secure funding from the federal government to keep it running.

Before the Tevatron closed, it was tantalizingly close to either discovering the Higgs Boson or proving it does not exist—which would change everything we know about physics.  The Large Hadron Collider (LHC) in Europe is also close.  And another particle accelerator in Europe, run by the same people who run the LHC, recently found evidence that one particle, the neutrino, can travel faster than light—which would also change everything we know about physics.

As an American, I wish the United States still had a large particle accelerator of its own so we could participate in these experiments, but at the same time I’m too excited to worry about patriotism.  One way or another, atom smashers are about to change physics, and when they do all kinds of new technologies will be possible.  The world of tomorrow is coming.

But That’s Impossible, Part 2

The neutrinos that allegedly travelled faster than light would undermine Einstein’s Theory of Relativity, one of the two foundations of modern science.  Quantum mechanics, the other foundation, is also threatened not by a recent discovery but by the lack of a discovery.  The Higgs Boson is still missing.

In quantum mechanics, everything that happens in physics can be explained by the existence of some particle.  Light and electricity are explained by photons.  Radiation is explained by alpha, beta, and gamma particles.  Mass is explained by the Higgs Boson, also known as the “God Particle,” but after years of searching scientists can’t find it.  They’ve tried almost every energy level where they thought it could be and got nothing.

It’s like when you lose your keys.  First, you look in the most likely places, such as the table by the door or under the sofa cushions.  Then you try less likely places until you’re forced to check in the bathtub or the refrigerator.  In the search for the Higgs Boson, scientists are now looking in the bathtubs and refrigerators of science.

The real shocking discovery would be if they fail to find the Higgs all together.  This would be like deciding the reason you can’t find your keys is because they never existed in the first place.  It wouldn’t make sense.

Failing to find the Higgs means our basic understanding of quantum mechanics is wrong.  It can’t be completely wrong, or nuclear power wouldn’t work, but we’ve messed up some detail somewhere, and scientists will have to go through the long and tedious process of finding that small mistake.  Unless they find the Higgs behind the ketchup in the fridge.

Oh, there they are.
