To the extent that experiment is getting a look-in, not just theory, there’s hope.
Are we “One Step Closer to Dark Matter in Universe,” (ScienceDaily, Oct. 31, 2011)? Some scientists say maybe:
The universe is still a mystery. We know what about 5 percent of the universe consists of. The rest is simply unknown. Researchers have gotten as far as knowing that a major portion, about 23 percent of the universe consists of a new kind of matter. No one has seen this matter, and no one knows what it consists of. …
One international research team that has taken a giant step toward finding dark matter with the help of a new method.
“We’ve looked at gamma radiation from dwarf galaxies. These galaxies are small and dim, but extremely massive, so they seem to consist largely of dark matter. Unfortunately we still haven’t detected a gamma signal from the dark matter in these objects, but we are definitely getting closer. Our new method involves looking at several dwarf galaxies at the same time and combining the observations in a new way, which yields excellent results. This is an exciting time for dark matter research, because we’re getting closer and closer,” says Maja Llena Garde.
We’ll be watching the file.
