Spacetime Vortices Discovered in Action For the First Time, Confirming Einstein’s Century-Old Prediction
- Astronomers observed frame-dragging around a supermassive black hole during a tidal disruption event, confirming Einstein's prediction on a large scale.
- The study used multiwavelength data from AT2020afhd to detect rhythmic changes in X-ray and radio signals indicating frame-dragging.
- The finding proposes a new method to study black holes by analyzing spacetime distortions caused by rotation.
- Cosimo Inserra described frame-dragging as a way to understand how a spinning black hole drags space-time and influences nearby objects.
- Frame-dragging may help unlock further secrets of black holes and their accretion dynamics.
- Tidal Disruption Events provide a laboratory to study how black holes influence their environments.
- AT2020afhd produced a plasma disk and jet, with short-term signal changes linked to frame-dragging.
- The research appears in Science Advances and introduces observational markers for gravitomagnetic effects.
- Physicists hope frame-dragging studies will broaden understanding of black hole mechanics and TDEs.
- The work marks a milestone in directly measuring frame-dragging on cosmic scales.
