This is the smallest observable measurement we’ve made: https://www.google.com/amp/s/futurism.com/physicists-have-measured-the-smallest-division-of-time-ever-observed/amp/
It’s a fun read.
Hope it helps you understand the term measurement
Since all electrons have EXACTLY the same charge and mass the only way we’d ever be able to tell them apart is to make to observations at the same time.
And by the same time I’d assume time to be in Planck terms.
Could we conclude that if we indeed observed 2 at the exact same time then the...
My question was inspired by an episode called spacetime on PBS about the one electron universe thought noted in a nobel prize speech: https://en.m.wikipedia.org/wiki/One-electron_universe.
So I thought why not observe 2 electrons at the same “time”.
