Publisher's Summary

The black holes that produced the first detected gravitational waves may have exotic origins in the early universe. When the Advanced Laser Interferometer Gravitational-Wave Observatory, LIGO, glimpsed gravitational waves from two merging black holes, scientists were surprised at how large the black holes were - about 30 times the mass of the sun.

"LIGO Find Offers Dark Matter Hint" is from the September 3, 2016 issue of Science News.
