Black Hole Mergers Reveal Intriguing Link to String Theory

Rapid Summary:

• Gravitational wave detections, first observed in 2015 at LIGO, have become routine, with nearly 300 events recorded via LIGO-Virgo-KAGRA collaboration since then.
• New research links gravitational wave observations to mathematical structures from string theory, specifically six-dimensional Calabi-Yau manifolds.
• The study focuses on scattering events (near-miss interactions) between black holes and neutron stars rather than mergers (collisions).
• Researchers used high-order mathematical complexity to model black hole behaviors, achieving results comparable to numerical simulations for distant deflections but diverging in near-collision cases.
• Implications include applications for waveform templates critical for next-generation gravitational-wave detectors like the Einstein Telescope and Cosmic explorer launching by the late 2030s.
