Are Planck Lengths Constant?

[ranyart]

Here is a great paper, obviously overlooked here, but not at (superstringtheory.com)

Anyway it has some major consequences for new thinking, like asking the above question in the post title.

It is definately a important paper, and although it will no doubt stir the imagination in the reader, it should clarify a very important direction for string v lqg disscutions going on in forums.

hello ranyart, I got the address for the abstract
http://arxiv.org/gr-qc/0310096
in case anyone wants to check the abstract out, like dipping a toe
in the water before jumping in. Looks like just 12 pages, so
an easy download in any case.

The paper you have shared is indeed an important contribution to the ongoing discussions about Planck lengths and their constancy. The concept of Planck length, also known as the quantum of length, is a fundamental unit of length in quantum mechanics and is defined as the distance at which quantum gravitational effects become significant.

According to the paper, Planck lengths are indeed constant and do not vary with changing conditions or in different regions of space. This is consistent with the current understanding of the Planck length as a fundamental constant in physics.

The paper also highlights the implications of this constancy for string theory and loop quantum gravity, two major theories attempting to reconcile quantum mechanics with general relativity. Understanding the constancy of Planck lengths is crucial for these theories to make accurate predictions and provide a deeper understanding of the fundamental nature of the universe.

Overall, this paper serves as an important reminder to consider the fundamental constants in our theories and to further explore their implications. It is a valuable contribution to the ongoing discussions and should be taken into account in future discussions and research. Thank you for sharing this insightful paper.
