# Is there a minimum distance? [duplicate]

I would imagine there is no limit to how small space can get. Is this correct? I am aware of planck's constant, but cannot objects be closer than Planck's constant is short?

Perhaps this question is simpler than I am making it to be. Regardless, an answer is appreciated.

• Planck's constant is not a distance, but look at Planck length: en.wikipedia.org/wiki/Planck_length – user81619 Oct 29 '15 at 1:38

• I think you might want to look up Planck length. – user37343 Oct 29 '15 at 4:29

I guess you are talking about the Planck lebgth, not the planck-constant.

But this is no minimum distance either. Its just the minimum space in which action can be defined. Its the distance, which is traveled trough by light in one planck second.

But that does not mean it is the smallest distance to exist.
