The art of catching cosmic rays. They were first detected on a hot air balloon ride -- equipped with radiation detectors. They can be seen from telescopes that can see the specific type of gamma rays that they give off when they hit air molecules, and the "air showers" of debris particles that reach the ground can be detected using arrays of water tanks on the ground. Low energy cosmic rays are common, while particles like the "OMG particle" seen in 1991 are extremely rare. Where do they come from? Low-energy cosmic rays come from supernovae. The high-energy cosmic rays might come from quasars and gamma ray bursts. And the high-energy particles? No one knows. There's a cosmic particle accelerating elephant in the room.

- Yeah, I think so and new chips have error-correcting codes, so when a bit gets flipped, they can tell and flip it back.34w
