Dirac large numbers hypothesis

The Dirac Large Numbers Hypothesis is a set of ideas proposed by physicist Paul Dirac in 1937. It explains why some numbers in the universe, like the age of the universe, and the ratio of the strength of gravity to the strength of electromagnetic forces, are so much bigger than anything else. According to the Dirac hypothesis, these numbers were created extremely early in the universe's history, and because they were so big to begin with, they have stayed big all this time. This means that something happened in the very first moments of the Universe to create these huge numbers, and then remained the same ever since.
