New Quantum Insights into Life and Death of Black Holes –Confirms Einstein & Hawking

Their findings dispel the so-called firewall paradox which shocked the physics community when it was announced in 2012 since its predictions about large black holes contradicted Einstein’s crowning achievement – the theory of general relativity. Those results suggested that anyone falling into a black hole would be burned up as they crossed its edge – the so-called event horizon.

Now Sam Braunstein and Stefano Pirandola have extinguished the fire. In a paper published in Physical Review Letters, they invoke quantum information theory, a modern branch of quantum mechanics that treats light and atoms as carriers of information. The key insight from quantum mechanics is the existence of `spooky’ quantum entanglement across a black hole’s event horizon.

“Quantum mechanics shows that entanglement can exist across the event horizon, between particles inside and outside the black hole,” says Braunstein. “But should this entanglement ever vanish, a barrier of energetic particles would be created: an energetic curtain (or firewall) would descend around the horizon of the black hole. We are the first to show the necessity of entanglement across all black hole event horizons and to consider what happens as black holes age. The greater the entanglement, the later the curtain descends. But if the entanglement is maximal, the firewall never occurs. Indeed, entanglement has long been believed to exist for some types of black holes, taking on exactly this maximum value. Our work confirms and generalizes this claim.”
