Discussion Overview

The discussion revolves around the relationship between the concept of time, specifically t=1 second, and the Planck length in the context of gravitational attraction between an electron and the Earth. Participants explore the implications of calculations involving these concepts, questioning the significance of measurements smaller than the Planck length.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant calculates the gravitational attraction between an electron and the Earth, yielding a displacement of 7.48 x 10^-54 meters, which is smaller than the Planck length.
  • The same participant expresses confusion about the meaning of measurements smaller than the Planck length, citing it as the "quantum of length" and questioning its significance.
  • Another participant seeks clarification on the interpretation of 't' in the calculations, specifically asking if it is taken as 1 second.
  • There is a distinction made by one participant regarding the term "quantum of length," suggesting that the phrase does not necessarily imply the smallest meaningful measurement of length.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the implications of measurements smaller than the Planck length or the interpretation of time in the context of these calculations. Multiple viewpoints remain regarding the significance of the Planck length and the definitions used in the discussion.

Contextual Notes

There are unresolved assumptions regarding the definitions of time and length in the context of quantum mechanics and gravitational interactions. The calculations presented depend on the interpretation of physical constants and their implications in theoretical frameworks.

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'.
