Record-Breaking Forbidden Black Hole Collision Might Finally Have an Explanation
Overview: A record-breaking cosmic collision Astronomers have announced a breakthrough in explaining the universe’s most massive black hole merger to date. In what scientists are framing as a potential solution to a long-standing paradox, two black holes once deemed “forbidden” by prevailing theories appear to have formed and merged in a way that defies previous…

Record-Breaking Collision of Forbidden Black Holes: New Explanation Emerges
New Insights into the Universe’s Most Massive Merger In a landmark development, astronomers have traced the origins of the most massive black hole merger ever observed, offering a plausible pathway for the formation of two almost unfathomably large black holes. For years, researchers grappled with the idea of “forbidden” or “impossible” black holes — objects…

How Record-Breaking Black Hole Collision Could Redefine ‘Forbidden’ Giants
Introduction: A Collision That Defied Expectations In a discovery that challenges long-held beliefs about black holes, scientists have traced the origins of the most massive black hole merger yet observed. The collision involved two black holes whose sizes were once considered nearly impossible within standard models. This breakthrough not only identifies how such giants could…

Scientists Solve the Mystery of the ‘Impossible’ Black Hole Merger
Unraveling a 2023 Gravitational Wave Mystery In 2023, a gravitational wave signal captured by the global network of detectors captivated scientists and the public alike. Dubbed an “impossible” black hole merger, the event appeared to defy conventional theories about how black holes form and pair up. A year of careful reanalysis, waveform modeling, and cross-checks…

Impossible Black Hole Merger Solved: New Astrophysics
What made the event look impossible? In 2023, gravitational-wave detectors picked up a signal that stunned scientists: a merger event that seemed to involve two black holes with properties that defied established expectations. The ripples in space-time suggested a collision that should have been highly unlikely under standard models of black-hole formation and dynamics. This…

Squashed Orbits Behind Black Hole Collision: Clues to How Mergers Formed
Unraveling the Origin Story of a Black Hole Merger Scientists have taken a crucial step toward understanding how a dramatic black hole collision came to be, by examining a merger that occurred on a surprisingly squashed, or eccentric, orbital path. Detected by the global gravitational-wave network run by LIGO in the United States and Virgo…
