Surely they are talking about the gravitational properties of the voids,

"Swiss Cheese" Model Refines Dark Energy Calculations

"A group of researchers from Fermi National Accelerator Laboratory in Batavia, Ill.,
recently invoked what's called the Swiss-cheese model of the universe to explain why these
supernovae might appear to be moving faster away from us than they really are. The
universe is made up of lumps of matter interspersed with giant holes, or voids, somewhat
like Swiss cheese. In fact, last year, astronomers at the University of Minnesota, Twin
Cities, reported finding the king of all known voids, spanning one billion light-years. In
other words, it would take light -- which holds the title for fastest stuff in the
universe -- one billion years to go from one side of the void to the other!

"The researchers at Fermi said these voids might lie between us and the supernovae being
observed, acting like concave lenses to make the objects appear dimmer and farther than
they really are. If so, then the supernova might not be accelerating away from us after
all. Their theory claimed to provide a way in which dark energy might go poof.

"Vanderveld and her colleagues at Cornell University, Ithaca, N.Y., looked more closely at
this theory and found a few "holes." The group at Fermi had assumed a bunch of voids would
line up between us and the supernovae, but Vanderveld's group said, in reality, the voids
would be distributed more randomly -- again like Swiss cheese. With this random
distribution, the voids are not enough to explain away dark energy".

Vanderveld should have done the math.

Given the refractive index of a *void* is almost exactly 1.000000
(take it as far as you like), and the density of "ordinary"
intergalactic space is about 10 to 100 hydrogen atomes per cubic
meter:

The density of hydrogen at STP is 2 * 6.02252x10^23 * 1000 / 22.4 =
5.37725 × 10^25 atoms per cubic meter.
The refractive index of hydrogen gas at STP is about 1.000132

It has been shown that the refractive index of hydrogen at low
pressures is approximately linear in pressu

from a physics religion standpoint of course so far you have
completely ignored the dark matter and dark energy contributions to
this divergent lense disscussion and perhaps would have not ignored it
if you had any idea of how to do it!

God Knows!

YOU PEOPLE can NOT of course say with any certainty that time, and
space, and matter of all types you think exist and the "physical laws"
that govern such will not just END in the next second!

and even if you could, you extrapolate the "physical laws" you think
you know back some 10,000,000,000 years and act as if YOU KNOW that
THEN they of course applied during the whole stretch of time until way
back then.

God must laugh at you and so do i!

have you no sense of humor?

it IS funny!
