Are black holes fuzzy or bald? This question is intimately connected with the greatest puzzle in modern physics: How can general relativity be merged with quantum theory?

Gravitational waves, like those recorded at the Virgo interferometer near Pisa, Italy, are helping scientists test if individual black holes have unique qualities. www.quantamagazine.org/astrophysici...

🌌 Welcome GW231123 🌌 The most massive black hole binary ever detected by @ligo.org / Virgo / KAGRA! 💥 The remnant #BlackHole has approximately 260 solar masses! CENTRA researchers are studying the origin of such an extreme event! Stay tuned! 🔗 arxiv.org/abs/2507.08219
