Fine Tuning Constants: Understanding Variables and Ratios | Physics NIST

Click For Summary
SUMMARY

This discussion focuses on the variables and ratios involved in the fine-tuning of physical constants as outlined by the NIST database. Participants seek clarity on which constants from the NIST list are used in calculating specific ratios, along with the relevant equations. Additionally, the sensitivity of these constants and the implications of their variations are crucial points of inquiry. The discussion references specific NIST resources for further exploration of these constants.

PREREQUISITES
  • Understanding of physical constants and their significance in physics
  • Familiarity with ratios and their mathematical implications
  • Basic knowledge of equations used in physical theories
  • Awareness of NIST resources and their relevance in scientific research
NEXT STEPS
  • Research the specific constants listed in the NIST database related to fine-tuning
  • Study the equations that involve ratios of physical constants
  • Explore the sensitivity analysis of constants and their impact on physical theories
  • Review Bernard Carr's videos for insights on constants not listed in the NIST database
USEFUL FOR

Physicists, researchers in theoretical physics, and students interested in the implications of physical constants and their ratios in the context of fine-tuning the universe.

This isn't a question about whether the universe is fine tuned or not. Which is more of a philosophical issue than a physics one. This is whether anyone on here knows of the variables involved from the following http://physics.nist.gov/cuu/Constants/Table/allascii.txt in the "fine tuning" findings. If some of the "fine tunings" are ratios, could a responder perhaps mention which constants from that list are involved in calculating the ratio and what the equation is, so that people can understand what the ratio is, and how the value is arrived at.

Furthermore it would be great if the responder knew how sensitive the constants or ratios were, and what difference it would make if they lay outside of the range (if not it doesn't matter).

A big ask I guess, but I thought there might be an expert on here. I watched some Bernard Carr videos, but couldn't see some of the constants he mentioned on the list, and didn't know how to derive them, so thought I'd try here for some help.

Thank you, I'll take at look at it now :)
