But, in 1998, it was discovered that the actual value of q was negative, courtesy of type 1a supernova redshift measurements. This marked the point at which dark energy, a repulsive force counteracting gravity, was introduced.

This paper, published yesterday, questions whether type 1A supernovae actually have constant brightness. If this is the case, one of the original justifications for the existence of dark energy may have to be reconsidered.

The others are right. Not slowing. We assumed gravity would slow it down and maybe even reverse it but the opposite is true. The expansion is accelerating. One of those big mysteries. We don’t know why but we gave the cause a label anyway. Dark Energy. Might as well have called it Batman or Ether. We don’t have much of a clue what it is yet.
