| Oct 2, 2019 at 14:17 | comment | added | MrSpudtastic | To clarify, instead of galaxies getting pushed away from each other, think of it like more space is being created between them and where they're going. They aren't necessarily moving, but still end up farther away. This also means that if we were to travel through space and target a specific destination, we would actually travel across a greater distance than what was there when we began travelling, because that extra distance would have been created by the expansion of space-time as we traveled. We'd end up traversing a greater distance than what even existed when we started. | |

The galaxies don't even have to move relative to one another, but they will still end up farther away from each other because space itself is literally getting bigger. So, it's not so much that galaxies are moving towards emptier zones of the universe, but that these empty zones are constantly being created and expanded, because "empty space" is getting bigger. | |

| Oct 2, 2019 at 5:04 | comment | added | Stu Smith | I once read (forget the source) that the universe's expansion can be visualized through baking raisin bread: raisins represent galaxies, and the dough represents space between the galaxies. Thus, as the dough rises, each individual raisin "sees" every other raisin moving away from it. In addition, distant raisins move away faster than closer raisins because there's more expanding dough in between. Although I prefer chocolate chips... | |
