New 'Mystery Meson' Sub-Atomic Particle Discovered
securitas writes "The BBC reports that scientists in Japan have discovered a new sub-atomic particle that defies current theories of matter and energy. The 'mystery meson' X(3872) was revealed while studying beauty quarks at the KEK High Energy Accelerator Research Organization Tsukuba meson factory. 'It weighs about the same as a single atom of helium and exists for only about one billionth of a trillionth of a second before it decays into other longer-lived, more familiar particles.' Scientists say the lifespan 'is nearly an eternity for a sub-atomic particle this heavy' and may require a change in current theory. Possible explanations for this include the particle being comprised of two quarks and two antiquarks, instead of the usual one-one pairing. More explanation and illustrations at KEK."
Overall, money invested in science has historically paid off at better than 10-1. You see a lot of projects that dead-end or don't produce all that much of value, but every once in awhile you get a major, bonanza strike. Problem is, you can't tell which projects will be the big hits until afterward, so it looks like a big waste of money.

It isn't. We're still benefiting (enormously!) from the basic research done in the 1950s; they had ideas back then we still haven't fully tapped. Every time someone looks back at one of those obscure reports and says "hey, wait a minute!".... it's a payoff. We have long, long since paid off the money we invested in the 1950s, and made a handsome profit to boot. Everything after that is gravy.
Research... the gift that keeps on giving.
"Another Contradiction" is much too strong a statement. The Standard Model has two problems (1) it doesn't play well with gravity, so it can't be the "final answer", and (2) it is so ridiculously successful that no one knows quite where to go next in theoretical particle physics. The SM is more or less able to give the right answer to any question we're able to ask it, right up to the edges of black holes or the first tiny fraction of a second after the birth of the universe. There are some problems too complex for our calculational techniques and approximations (i.e. we can't calculate the physics of many bound states precisely or derive human behavior), but there aren't really any contradictions. The recently reported new particle is more likely to lead us to tell us our calculational approximations aren't very good, rather than that something fundamentally new (though one can always hope!) Particle physicists are always hoping to find something fundamentally wrong with the standard model - it's just an extremely good approximation to the right answer, and until the approximation breaks down you don't know how to improve it.
