the.com/locality
The universe's way of refusing to let information cheat and skip the line.
means A specific place or neighborhood, especially one considered in terms of its immediate surroundings.
from From Latin 'localis' (relating to a place), built on 'locus' meaning 'place' — the same root that gives us 'local' and 'location.' The word entered English in the 1600s, first in the physics-adjacent sense of 'the fact of having a place,' before loosening into the everyday meaning of 'a particular neighborhood or area.' Physics later borrowed it back for the principle the essence above is winking at: that cause and effect can't outrun space, no shortcuts allowed.
- core claim
- nothing influences anything faster than light
- einstein's hope
- he wanted it to save realism from quantum weirdness
- bell's challenge
- experiments show nature violates it anyway
- loophole hunters
- physicists still debate if locality or realism should die
