“You’ve heard of electric cars and e-books, but now we are talking about electric dark matter,” said Julian Munoz of Harvard University. “However, this electric charge is on the very smallest of scales.”
Although the type of particle that makes up dark matter is still a mystery, a NASA team using the Hubble Space Telescope has made a very compelling observational test for the cold dark matter model that passes “with flying colors,” said Tommaso Treu of the University of California, Los Angeles (UCLA), a member of NASA’s team who used a new “cosmic magnifying glasses” technique that found that dark matter forms much smaller clumps (image above) than previously known, confirming one of the fundamental predictions of the widely accepted “cold dark matter” theory.
“The first galaxies in the early universe may illuminate what type of dark matter we have today,” says Mark Vogelsberger, associate professor of physics in MIT’s Kavli Institute for Astrophysics and Space Research. “Either we see this filament pattern, and fuzzy dark matter is plausible, or we don’t, and we can rule that model out. We now have a blueprint for how to do this.”
