@AndrwMol @StartsWithABang I think in GR, if you model an orbit using the Schwarzschild metric, only the central mass bends spacetime, not the "test particle". Whether that's a photon, or the Earth, its affect on spacetime is considered null.
@TAndersen_nSCIr@StartsWithABang So... basically misrepresenting the truth.
It turns out precise observations of the Milky Way don't call for dark matter or MOND.
@StartsWithABang Both the dark matter crowd and MOND minority are in denial about the GAIA results of a Keplerian decline in the Milky Way.
That says basically everything you need to know about their objectivity.
@SeamusBlackley That's pretty optimistic. We saw "impossible early galaxies" way before JWST.
Bigger telescopes don't mean people give up their long cherished beliefs. They just get more convoluted reasons for being dogmatic.
@skdh Is there a possibility that time simply was slower in the past, rather than the universe expanding?
Seems like that would resolve "impossible early galaxy" problems and the like.
@StartsWithABang Science takes something simple and direct, and builds it into esoteric, complex things.
It also takes esoteric, complex things, and makes them simple and direct.

They're probably not actually compact.
In the big bang theory, there is an angular diameter turnaround at z=1.6. Anything farther than that should start to appear larger on the sky, rather than smaller as we would expect.
That's probably not real.
