View Full Version : Why does the Plank length depend only on G, c and h?

The question I am trying to answer is:
'Explain why you would expect the Plank length to depend on the three fundamental constants G, c and h, ie assume that there is some function with f(lp,G,c,h)=0'

I looked in a few books but they just say something like 'the Plank length is determined by these constants' but don't say why :(
