Well, we believe the Universe is expanding because of Red Shift. And we presume that the expansion is accelerating because objects we presume to be farther have higher red shifts.
But, there appears to be a big flaw in the interpretation that Red Shift equates to expansion. Recent discovery of "Quantized Red Shifts" seems to invalidate Hubble Red Shift as expansion hypothesis. Why would Red Shifts be quantized? Shouldn't it be uniform if Red Shift is an manifestation of an expansion movement? Anyways, I think it may be time to seriously question the Big Bang/Expanding Universe paradigm. That way, we don't have to come up with Pixie Dust explanations such as Dark Matter or Dark Energy.
