When physicists announced in September that they had observed neutrinos traveling faster than the speed of light, the scientific community was justifiably skeptical. More »

Amidst the dubious news of neutrinos potentially traveling faster than light, it's easy to lose sight of something even stranger: neutrinos are in a constant identity crisis, oscillating between different types. Why is this? In this week's "Ask a Physicist" we'll find out. More »

Results from independent cross-checks of last month's FTL neutrino findings wont start rolling in for at least a few more months. In the meantime, however, physicists at the OPERA lab who made the initial observations will be running their experiment yet again — only this time they'll be measuring things a little differently.

There's been a lot of hubbub about the possibility of FTL neutrinos. But would breaking the light barrier really be such a big deal? Hell, yes, it would! In this week's "Ask a Physicist," we'll find out why. More »

A week ago, who among us would have guessed that light, the universe's ultimate speed demon, would be observed getting outpaced by a bunch of reckless neutrinos? Yes, these observations will obviously need to be checked and rechecked, but it just goes to show that you rarely know as much about something as you think you do. More »

Looks like Einstein may have been wrong — An international team of scientists at CERN has recorded neutrino particles traveling faster than the speed of light. More »

We're pretty much certain that dark matter exists, but we're still working to nail down precisely what dark matter is. One leading candidate, known as the WIMP, might be trapped inside the Sun, sucking heat away and altering fusion reactions. More »

In this week's "Ask a Physicist," I get counter-factual and imagine what would happen if we had perfect control over neutrinos. Would we build a death ray? Escape from an Inception dreamscape? Here's what would really happen - sort of. More »

A massive particle detector located a mile underground has found bits of antimatter known as geo-neutrinos deep inside the Earth. The find proves the Earth derives most of its power from radioactivity and could help us predict volcanoes and earthquakes. More »

Click to viewIf we received a message from an extraterrestrial civilization, would we necessarily realize it? SETI has long scanned the skies for evidence of alien transmissions, while others have proposed a hunt for physical artifacts sent by our distant neighbors. But neutrino physicists at the University of Hawaii have proposed yet another possibility: that humans have already received an extraterrestrial communication, and that we might find the message in our existing observations of the stars.
