Excerpt from thewestsidestory.net
The discovery throws new light on the currently accepted view of the
universe expanding at a faster and faster rate pulled apart by an
unknown force called dark energy this observation resulted in 2011 Nobel
Prize for Physics.
The researchers felt that the accelerating universe can be explained
on the basis of color difference in between two groups of supernova
leaving less acceleration than earlier assumed and in the process will
require lesser dark energy.
Milne said, “We’re proposing that our data suggest there might be
less dark energy than textbook knowledge, but we can’t put a number on
it, until our paper, the two populations of supernovae were treated as
the same population. To get that final answer, you need to do all that
work again, separately for the red and for the blue population.
Type la supernovae are considered as a benchmark for far away sources
of light they do have a fraction of variability which has limited our
knowledge of the size of the universe.
