PAM Dirac had found a number with dimension time using fundamental constants like mass of electron, universal gravitational constant, speed of light and so on.
This number that he had found coincided with the age of the universe.
How to replicate his formula for age of universe? What will be the actual relation?
This is also known as Dirac's Coincidence,
or Dirac's Large Number Hypothesis.
