Quantum eavesdropping could work even from inside a black hole

Black Hole Found Consuming its Own History

One of the common misconceptions about black holes is that they devour not only matter, but also the history of that matter. So when a black hole forms, you can only guess how it came to be. That isn't entirely true. Informational history is only lost when matter crosses the event horizon, and perhaps not even then. The material surrounding a black hole still has a rich history. In a recent study, astronomers have used that history to uncover th…

James Webb Space Telescope's observations of galaxy rotation direction startle scientists. James Webb Space Telescope observations have startled astronomers. According to scientists, the observations made by the space telescope may indicate that our universe exists inside a black hole. Based on observations by the space telescope that began in the summer of 2022, scientists have noticed that most galaxies rotate in the same direction. About two-…

Listening that hides inside a black hole could still get information about quantum objects on the outside, a finding that reveals how effectively black holes destroy quantum states near their event horizons An observer hiding inside a black hole can listen to quantum objects [...]

Eavesdropping in Black Holes: Quantum Communication Possible within Event Horizons

Observers hiding inside a black hole can eavesdrop on quantum objects outside it Van Van/Shutterstock Quantum eavesdropping is possible in at least one direction, in one direction, in one of the most impermeable universe boundaries: black hole event horizon. Dane Danielson At the University of Chicago, Illinois, we wanted to know how space-time structures, how [...] Source The post Eavesdropping in Black Holes: Quantum Communication Possible wit…

Quantum eavesdropping could work even from inside a black hole

An eavesdropper hiding inside a black hole could still obtain information about quantum objects on its outside, a finding that reveals how effectively black holes destroy the quantum states near their event horizons
