Physics, Astronomy & Cosmology / How do galaxies keep a stable size?
« on: 23/05/2019 11:35:49 »
Peter has this cosmic query:
How can each and every galaxy, given their multiplicity of sizes and shapes,exist in a finely-tuned dynamic equilibrium with the expansion of space such that no individual galaxy expands or contracts?
Can anyone expand on an answer?
