What is a Planck Length?
The Planck Length is a fundamental unit of length in quantum gravity. It is defined using fundamental constants: the speed of light, the gravitational constant, and the reduced Planck constant. Its approximate value is ≈1.616×10 −35 meters, representing a scale where quantum effects of gravity are expected to become significant.
What is a Light Year (ly)?
The light year is a unit of distance that represents how far light travels in one year in a vacuum. It is commonly used in astronomy to describe interstellar distances.
