The Milky Way
The galaxy in which our star system Sol resides.
It resides within the DERN Universe.
It is approximately 110,000 light-years across.
The first genuinely recognisably human forms of life were created on the oldest planets of our galaxy about 9,000,000 to 12,000,000 years ago, and, before these then became real humans, who could really be designated human, certainly yet nearly another 1,000,000 years passed, or perhaps even more.
The age of this galaxy amounts to close to exactly 810,000,000,000 years since the beginning of the first formations of gas.
The oldest systems of stars or planets in the outer and outermost realms of the galaxy’s spiral arms, indicate the same age, with insignificant differences which, as a rule, do not exceed 500,000,000 years.
The Sol system exists in the outermost realms of a spiral arm, and forms, so to speak, an enclave, and therefore the Sol system is one of the oldest systems in the galaxy.
In spite of its state, of being one of older solar and planet systems, it is, however, still a young system, in contrast to other systems in the most distant galaxies, because the Milky Way galaxy itself is still very young, with a total age of only 810,000,000,000 years.
Other further and very much further galaxies are much older, and these naturally also show very much older solid material, because naturally, due to of the greater age of the galaxies, their suns and planet systems are also older.
The Milky Way contains approximately 7,000,000 systems with planets upon which higher forms of life exist.
