Other evidences of the Galaxys' Acceleration

  1. May 27, 2015 #1
    According to my understanding, it is thought that the universe is not only expanding, but is also accelerating based on Doppler effect (light emitted by other galaxies have different wavelength.) Are there other evidences as well?
    Could not the galaxies acceleration be our observation of the milky way decelerating in a faster rate than other galaxy? (That would still have the same doppler effect as if other galaxies are accelerating.)

    Thank you,
