I saw this today and thought I should share it.

In short, there have been a handful of events detected by two neutrino detectors, ANITA and IceCube, that are nearly impossible to explain with the standard model. The confidence these events aren't from standard model particles is 5.8 sigma, which sound quite compelling to me. What do you all think? Have results like these evaporated before, or is this solid evidence of something new?
Article: There's something mysterious coming up from the frozen ground in Antarctica, and it could break physics as we know it.
Physicists don't know what it is exactly. But they do know it's some sort of cosmic ray—a high-energy particle that's blasted its way through space, into the Earth, and back out again. But the particles physicists know about—the collection of particles that make up what scientists call the Standard Model (SM) of particle physics—shouldn't be able to do that. Sure, there are low-energy neutrinos that can pierce through miles upon miles of rock unaffected. But high-energy neutrinos, as well as other high-energy particles, have "large cross-sections." That means that they'll almost always crash into something soon after zipping into the Earth and never make it out the other side.
