I finished my degree in astrophysics in 2010 while just was just a promise. Everyone was talking about how it would move things on and the last 6 months or so have been fascinating.

Cosmology is getting a real going over post Planck, its reminiscent of the 1890s when Kelvin talked about dotting Is and crossing Ts. The crisis in cosmology and now this, it's brilliant.

Do these '6 ancient galaxies',
(and presumably many other the JWT just hasn't been pointed towards yet),
mean that we,
(well astronomers, astrophysicists & cosmologists)
'need' less Dark Matter for current theories to hang together?

I don't know... And the implications are probably not that clear for now, if they do then out to be galaxies and not something else then there are a few parameters or assumption of the cosmological model that might need to be tweaked or worse.
