Hi I'm writing a scientific paper and want to write something along the line of:

"Static in time" objects are ...

Is there a single word describing time independent?

    Please supply more background information. Are these objects abstract entities, physical objects, geographical locations...?

  • Time-independent is a single word. Commented May 27, 2014 at 8:00

Something constant over time might be immutable or unchanging, in that it is the same now as it was before and as it will be in the future.

It may also be permanent if its existence is unchanging, or even eternal or timeless if time has no effect on it and/or it does not age.

  • Immutable was exaclty the word I was looking for thank you.

  • Then what you mean is static in space through time; i.e, f(t1) = f(t2) for all tn. "Static in time" makes no sense. Commented May 27, 2014 at 16:41
