I have calculated that an electron attracts the Earth according to F=GmM/r^2 formula just as well the Earth attracts it with a minuscule value and that yields to the acceleration of Earth towards the electron and again according to x=1/2 a t^2 formula Earth's CM move to an electron 7,48.10^-54 meters. But that is much smaller than Planck length.
I thought anything smaller than Planck length is meaningless.
"This is the ‘quantum of length’, the smallest measurement of length with any meaning."

How come?

What did you take 't' as?

also... smallest measurement of length with any meaning does not mean 'quantum of length'.
