Quest For Dark Matter Begins With A Few Tiny Bubbles


Northwestern University physicist Eric Dahl is part of a group of physicists that has just launched an unusual new experiment in an attempt to be the first to directly confirm the existence of dark matter.

Scientists this week heard their first pops in an experiment that searches for signs of dark matter in the form of tiny bubbles. The experiment’s one-of-a-kind detector is located in a laboratory a mile and a half underground in Sudbury, Ontario.

“For every gram of light matter, or atoms, in the universe, there are 5.5 grams of dark matter,” said Dahl, an assistant professor of physics and astronomy in the Weinberg College of Arts and Sciences. “It is still unknown what this dark matter is actually made of, but whatever it is, it’s something new. Physicists already have ruled out every known particle.

“If we do find dark matter, not only will we answer one of the biggest mysteries in cosmology and astrophysics, we’ll be seeing into a new world of particle physics as well,” he said. “The potential payoff is huge.”
