But other researchers have questioned attributing these seasonal variations that have been detected to dark matter.

Some experiments claim to have seen signals of dark matter in the form of annual modulation.

But for the other half it will be moving with this tide and less dark matter will hit.

This has posed a challenge for scientists trying to figure out where dark matter is.
Dark matter remains a mystery because there has been no direct observation of it, he explained.
CNN: Space station detector gives first clues to 'dark matter'
Planck data also suggest that our universe has more dark matter than previously thought.
"It is a so-called 'smoking gun' signal of dark matter annihilation, " Prof Bergstrom told the BBC.
Under supersymmetry, dark matter could be made up of fermions, which are superpartners of bosons.
Dark matter would be this lightest particle, called a weakly interacting massive particle, or WIMP.
Meanwhile, in space, scientists are looking for the signatures of dark matter and dark energy.
At least, in theory -- so far, no dark matter has been detected that way.
Among other things, this telescope is also looking for evidence of dark matter and dark energy.
Meanwhiel, in space, scientists are looking for the signatures of dark matter and dark energy.
Dark matter has nothing to resist gravity, so it collapses in on itself rapidly.
As dark matter particles steam through the detector, scientists hope that a few will collide with the argon atoms.

They point to a body of other evidence for the existence of dark matter.
More than half of the language, the authors wrote, is "dark matter" that has evaded standard dictionaries.
Many scientists are betting on this theory to explain some big cosmic puzzles, such as dark matter.
Dark matter was first detected in the 1930s, thanks to its gravitational effects on ordinary, visible matter.
But even if this question is solved, it will not reveal what all dark matter consists of.
The assumptions on which the existence of dark matter are based will thus rest on stronger foundations.
During the three month competition, there were 73 teams that submitted solutions to the dark matter problem.
Dark matter seems to be largely intangible, which means light (and everything else) very rarely bounces off it.
To see which bits of it are dark matter simply requires superimposing the known pattern of visible matter.
ECONOMIST: Cosmology: I spy with my little gravitational lens | The
We know there is dark matter - but we have to understand what this dark matter is made of.
BBC: Dark Matter: Experiment to shed light on dark particles
Dark matter comprises slightly more than 80% of the mass of the universe.
This covers territory at the top end where some other experiments have already reported tantalising hints of dark matter.
The other 96% consists of dark matter and dark energy, two mysterious substances about which very little is known.
WSJ: The Weekend Interview with Michio Kaku: Captain Michio and the World of Tomorrow
The Standard Model of Particle Physics describes all the known properties of nature (with the exception of dark matter).
By examining the resulting charge and light produced in this collision, scientists can determine whether dark matter was involved.
