Intergalactic space

Intergalactic Space



in Union astronomical terms it is the physical space between galaxies (often referred to as Deep Space) [1][2]

Union claims a 1 light year diameter 200,000 LY  "tunnel" of Intergalactic space  around the Bridge (and the other transgalactic connections between galaxies). The long term inhabitants of Z Point Station an other Intergalactic installations sometimes refer to themselves as "Intergalactics"

[1] The term Deep space is neither official nor accurare as it changes meaning with the advance of technology. At one point the space beyond the outermost orbit was called deep space, then the space between galactic spiral arms.

[2]Intergalactic space is the physical space between galaxies. The huge spaces between galaxy clusters are called the voids. Surrounding and stretching between galaxies, there is a rarefied plasma that is organized in a galactic filamentary structure.This material is called the intergalactic medium (IGM). The density of the IGM is 5-200 times the average density of the Universe. It consists mostly of ionized hydrogen; i.e. a plasma consisting of equal numbers of electrons and protons. As gas falls into the intergalactic medium from the voids, it heats up to temperatures of 105 K to 107 K, which is high enough so that collisions between atoms have enough energy to cause the bound electrons to escape from the hydrogen nuclei; this is why the IGM is ionized. At these temperatures, it is called the warm–hot intergalactic medium (WHIM). (Although the gas is very hot by terrestrial standards, 105 K is often called "warm" in astrophysics.) Computer simulations and observations indicate that up to half of the atomic matter in the Universe might exist in this warm-hot, rarefied state.When gas falls from the filamentary structures of the WHIM into the galaxy clusters at the intersections of the cosmic filaments, it can heat up even more, reaching temperatures of 108 K and above in the so-called intracluster medium.
