  "summary": "Active black holes are easy to detect. Their superheated accretion disks emit bright X-rays, and the jets streaming from their poles are easily seen at visible and radio wavelengths. But most stellar-mass black holes are inactive. They either drift through the galaxy alone or orbit a companion star without consuming its material. We can't observe inactive black holes directly. We can only observe…",
