We have a lot to learn about black holes and their place in the Universe. Two new gravitational wave detectors should tell us a lot.

When it comes to gravitational waves, we’ve detected dozens of them, both confirmed and candidates awaiting confirmation. But they all have one thing in common: they’re all from stellar mass black hole mergers. That’s because Virgo/LIGO can’t detect mergers of more massive black holes. They occur too slowly.
The paper is “Identifying heavy stellar black holes at cosmological distances with next generation gravitational-wave observatories.” The lead author is Stephen Fairhurst, Head of the Gravity Exploration Institute at Cardiff University. “We discuss the impact that these observations will have in narrowing uncertainties on the existence of the pair-instability mass-gap, and their implications on the formation of the first stellar black holes that could be seeds for the growth of supermassive black holes powering high-z quasars,” the researchers write.is a proposed GW observatory under consideration by several nations in the European Union. It promises more precise GW astronomy.
“Sources that are barely detectable by Advanced LIGO, Advanced Virgo, and Kagra will be resolved with incredible precision. The resulting explosion in the number of detected sources — up to millions per year — and the fidelity of observations will have wide-ranging impacts in physics and astronomy,” the CE website says.Both these detectors will allow us to find BH mergers in the ancient Universe.
