B Is it possible to do experiment on the Planck scale?

  1. May 26, 2016 #1
    I was wondering if experiments on the Planck length (about 10-35 m) are possible or not.
    If it is possible, what kind of experiment would that be?
    If it's not, then what is the problem? Or what is need to be done?

    I don't know from experimentally point of view what happen but there is the Heisenberg principle as limit in the measure process ...

    depending on what you want to observe? Maybe some parts can work right?

    Not with any currently imaginable technology. The smallest distances we've been able to measure are something around 10-18 meters, and that is fully 17 orders of magnitude away.

    I'm studying quantum control theory. So I thought if it could help to improve those small-scale experiments in the future.
    In principle, is it possible to observe 10-35 scale phenomenon?
    Or there is some kind of principle that tells us it is impossible (such as Heisenberg's uncertainty principle...).

    sure this will be usefull for future experiments, regarding the Heisenberg principle as you said you can concentrate your attention measuring exactly the space (for example) where you find a particle but in the other side you don't know the momentum so the velocity ... this doesn't permit you to have a complete description of the system ...

    before I replied to @tommyxu3 and I gave an answer to the original question...
