# Is space continuous? [duplicate]

Take a particle, it has a position $$(x, y, z)$$ maybe it is $$(0.231, 8.962, 10.567)$$.

Is there a maximum precision to this? Is the space discrete or continuous? If it is discrete, how thin the measurement is between a point A and B in space?

If it is in fact discrete, the smallest length is expected to be on the order of the Planck length, $$\sqrt{\hbar G/c^3}$$, built out of Planck’s constant, Newton’s gravitational constant, and the speed of light. This distance is a minuscule $$1.6\times 10^{-35}$$ meters, so you can see why we haven’t detected any discreteness yet.
