How long is a realm?

There are 2 Billion time periods per planet.  Each time period lasts for Decaillions and Billions and Trillions of years until the pyramids of ancient egypt are built, until the pyramids of the aztecs and mayans are built, until the modern era has finish with half of each time period having ancient times and the other half is modern times.

There are 30 Billion timelines per planet with 1 time period per segments of each timeline.  Each timeline has 2 Billion time periods.

There are 1 Earthlike planets per galaxy in the 1st program.  

There are 7 Earthlike planets per galaxy in the 10th and 12th programs.  They are Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto with 2 moons orbiting each planet that are also Earthlike in all ways.

There are 1 Billion galaxies per realm.

Each "sets of realms" consists of Decaillion, and Billions, and Trillions of realms or more.  I don't remember exactly how many, but a lot, almost uncountable due to the large number.
