Imagine being a civilization alone in the void, and not even a generation ship could make contact with anyone else, even if they knew which direction to send it

- sharkweek 6y agoSounds like you have a sci-fi novel to write!

- pattisapu 6y agoStar Trek Voyager had an episode where the crew got lost in a void 2,500 light years across . . . pretty interesting. https://memory-alpha.fandom.com/wiki/The_Void_(region) https://memory-alpha.fandom.com/wiki/The_Void_(region)

- nwallin 6y agoThis article was written in 2007 about the Giant Void. [0] In 2013, the KBC Void [1] was discovered, named after its discoverers, Keenan, Barger, and Cowie. The KBC void is 2 billion light years across, twice the diameter and 8 times the volume of the Giant Void. Both the Giant Void and the KBC Void contain galaxies, the Giant Void containing 17 galaxy clusters, and the KBC Void containing the Laniakea Supercluster. [2] The Laniakea Supercluster contains the Milky Way. Something to imagine, indeed.

- spiralx 6y agoThe Local Void that we are on one edge of is about 150 Mpc across (~490 million light years) and contains several "void galaxies" such as NGC 6503, about 4 Mpc (17 Mly) from us: https://www.zmescience.com/space/the-local-void-mapped-043223/ https://www.zmescience.com/space/the-local-void-mapped-04322... https://en.wikipedia.org/wiki/NGC_6503 https://en.wikipedia.org/wiki/NGC_6503 Two tiny dwarf galaxies are in the process of leaving the Local Void due to the attraction of the galaxies surrounding it: https://www.space.com/33748-dwarf-galaxies-escape-cosmic-void-hubble-photos.html https://www.space.com/33748-dwarf-galaxies-escape-cosmic-voi...
- mmazing 6y agoUnfortunately that's actually what the future holds for the universe (as far as we can tell from current observations). The universe will expand so much that civilizations into the VERY distant future will not be able to see other stars and galaxies, and will have no way to know that there's more out there. It's quite sad actually.
- deepsun 6y agoWell, even one galaxy is too big for anyone. As one astronomer said, even one local arm of Milky Way is enough to fit all and every science fiction ever imagined. There's just too much stuff, that you don't need to think about other galaxies.
