i am as god made me, sir (a small object estimated to be between 100 and 1,000 metres (300 and 3,000 ft) long, with its width and thickness both estimated between 35 and 167 metres (115 and 548 ft))

two weeks pass...

I for one welcome Amaterasu, "one of the highest-energy cosmic rays ever detected".

This article was amended on 24 November 2023 to clarify some of the wording, based on agency copy, that was used in an earlier version regarding the speed of particles.

that copy:

Some charged particles in the air shower travel faster than the speed of light, producing a type of electromagnetic radiation that can be detected by specialised instruments.

idk maybe it's technically correct (mutters something about group velocity or c in a vacuum)

The Amaterasu particle has an energy exceeding 240 exa-electron volts (EeV), millions of times more than particles produced in the Large Hadron Collider, the most powerful accelerator ever built, and equivalent to the energy of a golf ball travelling at 95mph.

I would not want to be in its way, but a 95mph golf ball does not seem that cosmically terrifying?

what if that golf ball actually went through your brain?

"In September 2011, it was reported, in a major release by CERN, that a tau neutrino had traveled faster than the speed of light; however, later updates from CERN on the OPERA experiment indicate that the faster-than-light readings were due to a faulty element of the experiment's fibre optic timing system.[12]"

it aint over till…
