Gott (astrophyics) gave a lecture on galactic rotation curves, a hot new topic at the time (1981), showed calculations + how available data established that stellar velocities in nearby galaxies *were* within an order of magnitude of expected, so everything was okay so far.
Suffice it to say, this was Before Dark Matter, *long* before inflation was A Thing. People seemed mostly happy with Friedmann cosmology though there were clearly some warts that needed working out. Age of the universe was 15 billion years +/- a few billion, ... an annoying error bar but WAY, way better than Hubble's first estimate: 1 billion years (geologists: "Nope") which finally got fixed by better data on the Cepheids
