Say you have a perfectly precise machine and use it to move an object increasingly smaller distances of 0.1m, 0.001m, 0.001m and so on; would you ever reach a distance on such an incredibly small scale that pushing the object by said distance makes no change in space at all?

That even if you were to push the object by this distance in the same direction an infinite amount of times you could never get it to be 1m away from its starting point? I'm talking about a distance like 1/ one billionth the length of a quark.

> perfectly precise machine
OP knowledge is 2000 years behind. All atoms move randomly

>thermal agitation

Even ignoring that atoms move by vibration, also most materials aren't perfectly isotropic at small scale, so any "movement" of you machine could result in different results, see how hard is to control movement in nanometric sizes using piezo motors/electrostatic under ideal conditions.

You're 100 years behind in knowledge.

All particles move in expected ways, through evolution of wave function.

I know it would be implausible to build a machine like that, for the sake of this question I'm talking about a theoretically perfectly precise machine.

It doesn't even have to be the machine doing the moving, it could be a quantum computer simulation of an object moving on its own by ever smaller and more precise distances.

There's obviously a limit to precision which humans can observe, the question is if there is a limit to precision in the universe? Is there a point where something can move such a small distance away from a given starting point that it would have no effect on space-time meaning there wouldn't be any tangible difference if it never even moved that distance at all?

"Waves" of what?

Each particle has a wavefunction for which each particle we see is part of it. Thats the wave function of a particle.

There's no randomness, its all deterministic all the way through.

You're not saying anything of use. "Waves" of what?

If it were determined then it would have happened already. Yet here we are in a universe that hasn't made up its mind.

The present state happened already, universe made up its mind.

Your question is nonsensical OP.
You posit a perfectly precise machine, then ask to physically quantify the results of using said machine, the space left etc.
But a physically pefect machine cannot exist in the real world that follows the law of physics
This cannot be meaningfully answered, because there's no physical meaning in the question.
> would you ever reach a distance on such an incredibly small scale that pushing the object by said distance makes no change in space at all?

What you mean to ask is, is there such a thing as a non-zero magnitude small enough that it is zero?
The answer is no.
This is the nature of the continuum.
If the distance is not zero, it is not zero.
You can always pick a smaller distance.

Really? What about the Planck length?
