Universe or Multiverse in Cosmos

According to Urantia.org, There are seven super-universes in the grand universe, and they are constituted approximately as follows:

The Universe where we are living is called "Nebadon" which is within Super-Universe called as " Orvonton".

It is said that Our Universe is quiet young compare to other Universes which is few Billion years old.

Super-universes. . . . . . . . . . . . 7

 Major sectors. . . . . . . . . . . . . 70

 Minor sectors. . . . . . . . . . . . 7,000

Local universes . . . . . . . . . 700,000

Constellations . . . . . . . . .70,000,000

 Local systems. . . . . . . . 7,000,000,000

Inhabitable planets . . 7,000,000,000,000

Each of the seven super-universes is constituted, approximately, as follows:

One system embraces, approximately. . . . . . . . . . . . . 1,000 worlds

 One constellation (100 systems) . . . . . . . . . . . . . . .100,000 worlds

One universe (100 constellations) . . . . . . . . . . . 10,000,000 worlds

One minor sector (100 universes) . . . . . . . . . 1,000,000,000 worlds

One major sector (100 minor sectors) . . . . 100,000,000,000 worlds

One super-universe (10 major sectors) . . .1,000,000,000,000 worlds

 All such estimates are approximations at best, for new systems are constantly evolving while other organizations are temporarily passing out of material existence.

The vast Milky Way starry system represents the central nucleus of Orvonton, being largely beyond the borders of your local universe.
