Dark matter search turns up empty

<<<Scientists using Earth-based experiments to detect particles of dark matter might now know why they keep coming up empty-handed: There may be no dark matter in the solar neighborhood — at least, not within 13,000 light-years, reports a study appearing in an upcoming issue of the Astrophysical Journal.
Though dark matter, a mysterious substance different from ordinary, visible matter, supposedly makes up more than 80 percent of the matter in the universe, the new work suggests that the solar system lives in a dark matter desert. That's a problem, because most scientists think the the Milky Way galaxy is embedded in a large halo of dark matter.
If the results hold, scientists will have to reconsider what sort of shape that dark matter halo takes, although it's unlikely to cause any major cosmological upheavals.
"This doesn't mean that dark matter does not exist," says study coauthor Christian Moni Bidin, an astronomer at the Universidad de Concepcion in Chile. "The result is only that dark matter is not where we expected it.">>>
Okay. So maybe this means the whole universe doesn't suck. By process of elimination then, we are left with the idea that there's a whole lot more pushing, at much greater scales than what we now think.
How the Casimir effect works
So this is an explanation of why dark energy increases. The more crowded the universe is, the fewer wavelengths are allowed. The less dense, the higher and higher integer multiples can exist between the masses that exclude them from the inside, but allow them on the outside The fewer and fewer. So pressure increases on the inside. Those waves in the animation integer multiples. They take effect only when an entire doubling of the distance has happened.
But I don't know nothing. I just listen.
