"Simultaneous" means at the same time.

"(Insert Word)" means at the same location.

(For people that like physics out there, I'm studying special relativity...and I hate the fact that my notes say: "Events that are simultaneous and happen at the same location in one reference frame are simultaneous and happen at the same location in all reference frames").

There HAS to be a shorter way to say it.


  • "Colocated" means at the same location, but doesn't fit neatly into your example. – nnnnnn Mar 13 at 1:21
  • @nnnnnn thanks! Yep, it sounds a bit weird...it fits though! I'm going to use that for now. – joshuaronis Mar 13 at 1:55

    They are temporally and spatially coincident. Does sound odd but works. Good Luck. – Kris Mar 13 at 10:19

  • Possibly: "Events that are simultaneous and are localised to one particular reference frame are simultaneous and happen locally in all reference frames". – Greybeard Mar 13 at 11:29

There is "co-located", but that is usually analogous to "synchronized": we deliberately put them at the same point in space (or time), it wasn't just an accident.

There are also "convergence", "intersection", even "collision". Since things cannot be in the same spot (simultaneously), how about "adjacent" or "adjoining"?
