Bizarre Particles Keep Flying Out of Antarctica's Ice, and They Might Shatter Modern Physics (livescience.com)
There's something mysterious coming up from the frozen ground in Antarctica, and it could break physics as we know it. From a report: 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. And yet, since March 2016, researchers have been puzzling over two events in Antarctica where cosmic rays did burst out from the Earth, and were detected by NASA's Antarctic Impulsive Transient Antenna (ANITA) -- a balloon-borne antenna drifting over the southern continent.
ANITA is designed to hunt cosmic rays from outer space, so the high-energy neutrino community was buzzing with excitement when the instrument detected particles that seemed to be blasting up from Earth instead of zooming down from space. Because cosmic rays shouldn't do that, scientists began to wonder whether these mysterious beams are made of particles never seen before. Since then, physicists have proposed all sorts of explanations for these "upward going" cosmic rays, from sterile neutrinos (neutrinos that rarely ever bang into matter) to "atypical dark matter distributions inside the Earth," referencing the mysterious form of matter that doesn't interact with light.

They we shouldn't store modern physics above Antarctica! Who's bright idea was it to put it there in the first place?
I browse on +1 so AC's need not respond, I won't see it.
The intern they hired to mount the sensor on the pole skipped the part about "This end up"
What if those "upward going" particles are a sign that something is happening in the mantle deep under the North Pole
What if you knew where Antarctica was located?
