Yes I too can contrive a thought experiment that combines a bunch of physical constants. It's hardly a construct. It's just a length. It might mean something. It might mean something when multiplied by pi or a tenth or whatever. It's the scale at which quantum gravity might maybe possibly could be important. Nothing more nothing less.
- gizmo686 9y agoI would not consider the explanation I describe to be a thought experiment, but rather a mathematical derivation; although I might showing my roots as a mathematician instead of a physicist there. Additionally, all the argument, as I presented it, shows is that there is some length beyond which we cannot observe. It turns out that we can calculate this length, and the result happens to be precisely the plank length. As a mathematician, this seems highly unlikely to be a coincidence; however I am not familiar enough with physics to know if this is a deep result, or a trivial consequence of it's definition. To clarify the disagreement: do you agree that our current theory predicts that there is some length beyond which we cannot measure?
- gaze 9y agoYeah, that would make sense, but I don't imagine it's a hard cutoff. It may be that you get diminishing information per unit energy at a length scale related to the Planck length or something.
