Intergalactic Space
The vast region of space that exists between galaxies, characterized by extremely low densities of matter and an absence of the concentrated populations of stars, planets, and other celestial objects typically found within galaxies.
Although often described as empty, intergalactic space contains diffuse gas, plasma, radiation, dark matter, and occasionally isolated stars and other objects. Much of its ordinary matter exists in the form of the intergalactic medium, which can include extremely hot, highly ionized gas.
Distances across intergalactic space can extend millions or even billions of light-years. Despite its extremely low density, intergalactic space plays an important role in the large-scale structure, evolution, and expansion of the universe.

"The Andromeda Galaxy is approximately 2.5 million light-years from the Milky Way, with an immense region of intergalactic space separating their main stellar populations."
"Dude, where the hell are we?"
"According to the GPS, we're about 3 million light-years outside the Milky Way."
"SO WE'RE IN INTERGALACTIC SPACE?!"
"Yes."
