"A new study used data from the Chandra X-ray Observatory, the Wide-field Infrared Survey Explorer (WISE), the ground-based Large Binocular Telescope in Arizona, the Sloan Digital Sky Survey (SDSS) and the Mapping Nearby Galaxies at APO (MaNGA) survey to identify the pairs. They are circling one another before they eventually merge. Finding the black holes could help astronomers understand how the objects produce such powerful gravitational waves when they finally combine."

The Universe will end as a giant black hole.

As these black holes merge and grow larger their gravitational pull will consume everything until the entire Universe becomes one singular black hole.

Gravity doesn't hoover up everything - the inverse square law applies even for black holes - and even the largest black holes eventually evaporate. I'm not sure where the entropy goes - most of the universe's entropy is contained in black holes (proportional to the area of their event horizons). The Bekenstein bound implies that black hole entropy is maximal.

How do you know you're not living inside a black hole right now?

Entropy will easily defeat the black holes when it comes to ending the Universe first.

Dark energy might rip everything apart long before heat death, black hole evaporation or proton decay hold sway.
