Hubble Finds 10 Times More Galaxies Than Thought
Does this have any implications for the amount of dark matter or do estimates of the energy content of the universe not rely on the number of observed galaxies? If the number of observed galaxies does not matter, how do we account for this factor of ten? Galaxies are probably not ten times lighter - ignoring dark matter - than previously believed. Are those missing galaxies just very light? Is the universe heavier than previously assumed? How does that change the expansions of the universe? Does there have to be even more dark energy to compensate for this additional baryonic matter to match observed expansion rates?
