Penrose Extraction Achieves 88.5% Success Rate With Kerr Black Hole Tuning
Understanding the Penrose Process and Kerr Black Holes For decades, physicists have explored whether energy can be extracted from rotating (Kerr) black holes. The Penrose process—proposed by Roger Penrose in 1969—describes how particles interacting within the ergosphere, the region outside the event horizon where space is dragged by the black hole’s rotation, could split in…

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…

Catalog Of Simulations Of Black Hole Collisions Expands
Overview: A Growing Repository for Extreme Spacetime Simulations The SXS—Simulating eXtreme Spacetimes—collaboration has long tracked the dynamics of some of the universe’s most violent events: mergers of binary black hole systems. Its catalog of simulations serves as a powerful theoretical backbone for understanding gravitational waves, helping scientists predict what waveform signals should look like when…
