Thread: Planck time

Is Planck Time a theoretical limit, or a real one? Is it a limit because practically there is "nothing smaller to measure", so might as well call it a limit for convenience? Or is it a real limit? If so, does that mean that everything moves in "jitters" of Planck Length? Like a pixel on a screen appears to move smoothly but is actually jumping around from pixel to pixel if you zoom in.

By the way, ducks are the best. I mean the birds that go "quack", not some sports team or movie. Who agrees with this, please?

I agree with the Ducks bit pyoko. But, really, is a duck a bird in the true sense? Were you making a play on words here pyoko? Quacks? Quarks? Planck Time is the time between two Quarks. westwind.

A good and valid question.
I don't think we have a definite answer to this one yet.

Any current practical measurement equipment we have or could even propose to build at this time is so far away from measuring the Planck Length (/Planck Time/Planck Energy etc etc etc) that we're definitely not close to answering that question experimentally. I'm not a theorist so couldn't comment on how this problem is regarded in String theory etc.Dan
