Dark-matter measurement looks unlikely

The claim by an experiment in Italy to have detected evidence of dark matter looks highly unlikely after a similar experiment in Korea failed to replicate the findings.

Astrophysicists know that there must be more to the Universe than what we can see because galaxies rotate at faster speeds than they should be based on the visible matter they contain. We’re surrounded by mysterious dark matter, but it has proved very difficult to detect, with so far only the DAMA experiment in Italy claiming to have found evidence for it.

Now, a team led by researchers from Institute for Basic Science in South Korea has analyzed data amassed over 1.7 years from a similar experiment and found no evidence to support DAMA’s results.

This contributes to mounting evidence from other sources that DAMA’s observations aren’t consistent with an observation of dark matter.
