The 5 craziest things we learned about the universe in 2017

Via The Washington Post, this: The 5 craziest things we learned about the universe in 2017

The article starts with “the most insane asteroid we’ve ever seen,” moves on with a tiny little Neptunian moon that has a ring, and ends with “the fact that the universe shouldn’t even exist” —

The Big Bang is believed to have produced equal parts matter and antimatter — but since the only difference between these two is their opposite electrical charges, the reaction should have resulted in a violent eruption.

Scientists at the European Organization for Nuclear Research have spent their careers trying to figure out why this didn’t happen. They’ve tried to find differences in the particle’s mass and electrical charge, among dozens of other properties, but everything comes up identical.

“All of our observations find a complete symmetry between matter and antimatter, which is why the universe should not actually exist,” Christian Smorra, the study’s lead author, said. “An asymmetry must exist here somewhere but we simply do not understand where the difference is. What is the source of the symmetry break?”

Lots of super-snazzy astronomical stuff over the past couple of years. I wonder what we’ll discover in 2018?
