Single Idea 23005

[catalogued under 27. Natural Reality / D. Time / 2. Passage of Time / g. Time's arrow]

Full Idea

The laws of nature are time-reversal invariant, with the small exception of the kaon (a type of sub-atomic particle)

Gist of Idea

The kaon does not seem to be time-reversal invariant, unlike the rest of nature

A Reaction

If that fact about the kaon were very secure indeed, then that would mean the collapse of the claims about the time-invariance of the laws. Since time-invariance is still routinely asserted, I assume it is not secure.
