   Format: MarkdownItexI have added to _[[microcausality]]_ a quote with a nice discussion. That also cites experimental bounds. But back from the 1970s only -- there must be better ones by now. Does anyone happen to know a citation for better experimental bounds, or else might anyone enjoy googling for it? I am out of googlin time now, but I am entertaining myself with advertizing this as an "experimental bound on higher category theory in fundamental physics", along the lines of the story [here](http://ncatlab.org/nlab/show/motivic+quantization#ExpositionIntroduction).
