And now for something completely physics geeky
2023's Nobel Prize was awarded for studying physics on tiny, attosecond-level timescales. Too bad that particle physics happens even faster.

And if it travels for 1 yoctosecond (10-24 seconds), it travels up to 0.3 femtometers, or 3 × 10-15 meters.
If your particles are atom-sized (about an angstrom), then attosecond timing will do it. If your particles are atomic-nucleus sized (about a femtometer), then you need yoctosecond timing.
That many particles don’t live long enough to obey the “rules” that should bind all subatomic particles. And that particles that live for short enough amounts of time don’t even have definitive properties like mass, instead existing only in an indeterminate state due to the quantum bizarreness of nature. As far as we’ve come in our understanding of the Universe, getting down to attosecond timescales simply isn’t good enough to account for particle physics and all that it includes.
