We may be about to solve one of the biggest mysteries in the universe

The discovery of gravitational waves in February is leading to remarkable new insights in physics. One of the most promising is identifying what dark matter is made of, the elusive missing majority of the universe that we know is out there but can’t detect directly. NASA Cosmologist Alexander Kashlinsky thinks that black holes could be the answer, and that detecting gravitational waves could be the best way to confirm it. Here’s how.
