What If The Universe Isn't Accelerating The Way We Think?

It seems that they are going to have to fall back and punt regarding the increasing acceleration of the expanding universe and the necessary amount of 'Dark Matter and Dark Energy' necessary to 'fudge' the existing equations to meet what they thought was happening. They assumed certain characteristics of Ig stars, whatever they are, to be uniform but it turns out on taking a deeper look that they are not. And the result was that they miscalculate what the expansion rate for observable reality was. So the fudge factor must be turned down a significant amount. No telling what the situation will be once they get all their ducks in a row.
How fast the universe has been expanding since the Big Bang is something of a puzzling question. It wasn't that long enough that we didn't know it was accelerating at all, and a new study finds the acceleration of the expansion of the universe might not be as fast as thought.

The currently accepted view of the universe expanding at a faster and faster rate, pulled apart by an unknown force labeled under the umbrella term 'dark energy', is based on observations that resulted in the 2011 Nobel Prize for Physics. But observations based on uniform type Ia supernovae - cosmic "beacons" - may actually fall into different populations.
That's like comparing 100-watt light bulbs only to find out they vary in brightness.
"We found that the differences are not random, but lead to separating Ia supernovae into two groups, where the group that is in the minority near us are in the majority at large distances -- and thus when the universe was younger," says astronomer Peter A. Milne of the University of Arizona. "There are different populations out there, and they have not been recognized. The big assumption has been that as you go from near to far, type Ia supernovae are the same. That doesn't appear to be the case."
Do the new guys get Nobel Prizes also or do the first set in 2011 have to pay theirs back? Life is hard. All that work and all those numbers crunched and all of those discoveries made and now to do it all over again.
