How to investigate the X Files of physics

CERN file

The Large Hadron Collider, shown here during its construction phase, is the locale where physicists hope many of their most puzzling cases will be solved. But there are other mysteries to ponder in the cosmos.

By Alan Boyle, Science Editor, NBC News

They may not be on a par with alien goo or liver-eating mutants, but there's a whole collection of real-life X Files that physicists are puzzling over. Some cases eventually will be solved, like the hunt for the elusive Higgs boson. Some will fizzle out, like the case of the faster-than-light neutrinos. And some will baffle the boffins for years and years, like the mystery of dark energy.

Two sharp-eyed truth-squadders discussed how scientists investigate the X Files of physics?? and how you can tell when a scientific case is really, truly closed?? on "Virtually Speaking Science," an hourlong talk show hosted by yours truly on Wednesday.

Sean M. Carroll and Matt Strassler aren't FBI agents, although they could probably teach Fox Mulder and Dana Scully of "The X Files" a thing or two about critical thinking. They're theoretical physicists (Sean at Caltech, Matt at Rutgers) as well as accomplished writers and bloggers. Carroll is the author of several books, including "The Particle at the End of the Universe," his account of the Higgs boson search. Strassler performs reality checks on the Higgs quest and other big topics in physics on his blog, "Of Particular Significance."

What kinds of X Files are we talking about? Here a sampler:

The proton problem is "one of those classic scientific puzzles where what's actually going on is probably some other type of issue in the experiment, or the interpretation of the experiment, that doesn't have anything to do with the radius of the proton," Strassler told me during our pre-show interview. "There's a small chance that it's something fundamental and really deep, but it's more likely to turn out to be some little detail."

That sort of thing goes on all the time in science, he said. In fact, some degree of uncertainty surrounds many of the experimental results produced by the scientific process. Professional scientists understand that's "par for the course," Strassler said. "The only thing that's unusual is the level of media attention."

Are there any tricks of the trade that regular folks can use to figure out how to judge a scientific claim's solidity? Actually, there are plenty. But Strassler's top tip is to develop a better understanding of how news outlets work, and how scientific announcements work.

"We all know how to read advertisements. We know they're selling us something," he said. "But we don't necessarily know how to read an article on the front page of The New York Times or an article in Newsweek. They have a big, exciting topic, but when you look closely, you realize that it's only one person saying this. Or there's been one experiment that shows this. If there's only one, it may be nothing. It may go away."

Carroll said scientists themselves are getting into the public outreach field ??either by blogging, as he does on Preposterous Universe, or by creating videos and other user-friendly materials about their research. "It'd be great if more scientists wanted to become regular contributors, to at least try to explain their most recent work," Carroll said.

"I can play devil's advocate on that one," Strassler said. "I worry about us generating so much information that no one's able to sift through and get to the meat of what we really know and what we don't."?

"That's a very interesting topic," Carroll replied. "There's a lot of information out there. In some sense, we could still use more, but it's a matter of finding it. That's the big challenge."
