it's covered in the video
tl;dw a bit flip can recreate the glitch, but it probably wasn't a cosmic ray that did it
I watched. I agree the cosmic ray explanation seemed extremely unlikely but I only knew that it was theoretically possible and that the mystery was never solved.
Had I known the hardware was faulty, I'd have probably suggested the RAM going bad was the most likely culprit which can cause bit flips as well.
I get that the tests didn't find any problems but I've had bad memory pass tests before so it's not a guarantee.
