What is the indivisible unit of Time called if the Atom is the concept of indivisible space?

Question

I know that there are smaller things than atoms!!!

...but its a concept of indivisible space. Is there an equivalent in time?

If not why was/is space considered to be indivisible at the smallest point and time not?

an atom (Greek ἄτομος or átomos meaning "the smallest indivisible particle of matter, i.e. something that cannot be divided"
historical concept
If space has this concept then why hasnt time?

Answer 1

The current best theories in particle physics (which means the smallest whatever before the theories explode) give the smallest unit of length and the smallest unit of time as the
Planck length and the Planck time, respectively, 1.6 × 10^{−35} metres, and 5.39 x 10^{-44} seconds.

I'm curious why you say the atom is the smallest indivisible element?

Answer 2

I would say that an "atom" is the concept for indivisible matter, not space. I'm not sure I've seen anything which would be the smallest indivisible unit of space. Certainly position variables in quantum chemistry are treated as continuous. So I guess my answer is "there is none for time, just as there is none for space."

Answer 3

if you want to consider that ATOM is "indivisible space" then its time equivalent would have to be the 'time taken by electron in the lower most shell' to make one revolution around the nucleus.

Answer 4

not that i know of

this may be as time is a single dimension, while space is 3...

i believe the smallest unit of time used is Planck Time, about 5.4x10^-44 seconds
