|I thought dark matter was hypothesized to explain the orbital velocities of stars within galaxies? It seems like that issue would be there regardless of where the galaxy came from in the first place.|
That's my understanding as well. Furthermore, the effects have of dark matter been observed pretty directly:
The history of dark matter also touches on the claim (in the statement Peter Henderson quoted) that dissent isn't tolerated. From what I recall taking intro astronomy in the late 90s, there was still quite a bit of resistance to the idea. Observation showed that something wasn't right, but there was still hope that it could be resolved in some way that didn't require inventing a whole new weird class of matter. Dark matter survived because it fit the evidence better than the alternatives, not because it's gospel of the big-bangist conspiracy.
