Acceleration of expansion of Universe not that fast?

  1. Apr 12, 2015 #1
    There is some surprising twist regarding measurements of accelerating expansion of Universe. Maybe it is not accelerating that fast as previously predicted. It seems that there is something questionable about Ia supernovae.

    What do you think about it? Is this real game changer or some minor glitch in data?

    Consider the source. Certain authors have certain prejudices about cosmological interpretations. That is not necessarily a bad thing, but, it provides a reference point. I think you should not take them more seriously than the source of claims contested without equally firm observational backing - which is often the main reason such papers are viewed as controversial, or ignored by mainstream scientists.
