A new model combines loop quantum gravity and dark energy, giving birth to a black hole with a triple horizon. This layered structure affects the shadow, vibrations, and light deflection, promising to become a key to testing quantum gravity and the nature of the universe's accelerating expansion.

When a black hole spins, it drags spacetime with it, like a spoon stirring thick honey. This cosmic vortex can alter the internal rhythm of quantum particles even when they feel no forces. Scientists have calculated that for a supermassive black hole this shift reaches 10²⁴ radians — a number that m

Physicists examined two classic time machine designs within extended gravity featuring an extra field. The time loops didn’t collapse, and the chronology protection hypothesis failed. Even souped-up gravity doesn’t forbid time travel, which matters for testing modified theories.
