🌌 Gravitational Shockwave! Biggest-Ever Black Hole Smash Detected, Record-Breaking Black Hole Merger Detected: GW231123 Challenges Einstein’s Limits
📰 Summary
In a cosmic event that has stunned scientists, two gigantic black holes merged to form a supermassive black hole weighing about 225 times the mass of the Sun. The powerful ripples created by this event — known as gravitational waves — were picked up by the LIGO-Virgo-KAGRA (LVK) Collaboration on November 23, 2023, and the event has been named GW231123.
This discovery not only sets a new record but also challenges everything we thought we knew about how black holes are born and grow.
Key Points:
- GW231123 is the most massive black hole merger ever detected via gravitational waves.
- The final black hole formed weighs about 225 times the mass of our Sun.
- LIGO-Virgo-KAGRA (LVK) detected the event during their fourth observation run.
- This event challenges current theories of stellar evolution and black hole formation.
- The merging black holes were spinning near the maximum allowed by Einstein’s theory.
🔍 What Are Gravitational Waves?
Gravitational waves are tiny ripples in space-time caused by massive cosmic events — like two black holes crashing into each other. These waves travel across the universe and were first detected in 2015 by LIGO, opening a new window into the universe.
🧪 Key Findings
- 225-solar-mass Black Hole: The largest black hole merger detected so far.
- Unusually Rapid Spins: The black holes were spinning extremely fast — close to the speed limit set by Einstein’s general relativity.
- Strange Origin: Scientists believe these black holes were formed by earlier smaller black hole mergers — a concept called hierarchical merging.
- Difficult to Explain: This massive duo can’t be explained by traditional models of how stars die and turn into black holes.
