Is there a way in theory to overcome the uncertainity principle in quantum physics?

I know that uncertainty has to do with the wave length of light and it effects on quantum particles in which you can either use long wave length light and not affect the momentum of a particle but you cannot get the accurate location due to long wavelength or you can use a shorter wave length higher energy light that will affect the momentum but give you an accurate location. Correct!? If we in theory could come up with a way to measure momentum and location without using light we wouldn’t have this uncertainty problem? Is my understanding correct or there something intrinsic in matter that will not allow for this to happen?


  1. “something intrinsic in matter that will not allow for this to happen?” Yes!
    It’s been a long time since I studied it, so here is a quote:
    “Moreover, his principle is not a statement about the limitations of a researcher’s ability to measure particular quantities of a system, but it is a statement about the nature of the system itselfĂ‚ as described by the equations of quantum mechanics.”
    I distinctly remember that being a main point among all those qm lectures.
    So shove the measurement limitation up your….

  2. You need a reflection to give a location.. However light in a quantum level takes time to perceive, therefore the location is not as accurate as we would like it to be. It sounds like you have a pretty good grasp on this theory. If you can come up with a way to measure location without using light you would be a billionaire

  3. There is something intrinsic… it’s called quantum jitters. Quanta, indeed all mass and energy, have associated waves (deBroglie). The difference between the quanta and the macro world is that the waves of the quanta are relatively much longer than the quanta themselves. So their waves are significant.
    Whereas, the waves associated with the macro world, including your body, are waaaaaay shorter than the body itself. So these waves are not significant and we can treat the macro world as deterministic, but the quantum world has to be treated probabilistically. Thus the uncertainties, the standard deviations, in the Heisenberg inequalities.
    You are right about the detector wavelengths. They must be shorter than the quantum wavelengths to detect, say, the location of a quantum. But even when that location is pin pointed, the momentum or velocity of that quantum becomes smeared across an unending interval of possibilities… the standard deviation approaches infinity. And that’s all due to its intrinsic jittery nature.

  4. No. A quantum when unobserved occupies a volume of space with some probability, the Psi Function. If you learn location, the other things like momentum are unknown. The better you know one thing the worse you can know the other. This is built into the nature of the universe. The act of measuring disturbs the observation.
