This is the basic argument. The Compton wavelength or equivalently the de Broglie wavelength with v = c is equal to the Schwarzschild radius. That is how to derive the Planck length. The argument that nothing smaller exists just means the Heisenberg uncertainty principle can't isolate some

There is a related concept, the Planck Mass that also involves the 3 most fundamental constants in nature, the speed of light the Planck constant and the Gravitational constant. If you take the Planck energy (c^5*h/2*PI*G)^1/2 and confine it in a box one Planck length (G*h/2*PI*c^3)^1/2 on a side

To measure small things you need comparably short wavelengths.  If you make a photon with a wavelength so short it can measure the Planck length it will have so much mass-energy that it will fold spacetime around it and become a black hole...so you won't be able to use it to measure any

What is the argument for the claim that we cannot, in principle, measure any length smaller than Planck length? TIA, AG -- You received this message because you are subscribed to the Google Groups "Everything List" group. To unsubscribe from this group and stop receiving emails fro
