What happens to mass in a black hole?
Once inside the black hole’s event horizon, matter will be torn apart into its smallest subatomic components and eventually be squeezed into the singularity. While everyone thought matter in a black hole was gone forever, Stephen Hawking in 1974 predicted that black holes could radiate energy away (Hawking radiation).
What happens to information in a black hole?
The black hole information paradox is a puzzle resulting from the combination of quantum mechanics and general relativity. Calculations suggest that physical information could permanently disappear in a black hole, allowing many physical states to devolve into the same state.
How do black holes have infinite mass?
If there are no particles in a Black Hole then what is there to interact with the Higgs Field to generate mass? A black hole has an infinite density; since its volume is zero, it is compressed to the very limit. So it also has infinite gravity, and sucks anything which is near it!
Is mass conserved in a black hole?
Black holes do not violate the law of conservation of energy. When gas or other material falls past the point of no return (called the event horizon) and into a black hole, the exact amount of energy (including mass) contained in the material as it falls in is added to the black hole.
Is information preserved in a black hole?
By the logic of this duality, if you have a black hole in the bulk, it has a simulacrum on the boundary. Because the boundary is governed by quantum physics without the complications of gravity, it unequivocally preserves information.
What happens when matter falls into a black hole?
These motions imply a dark, massive body whose mass can be computed from the speeds of the stars. The matter that falls into a black hole adds to the mass of the black hole. Its gravity doesn’t disappear from the universe. This animation illustrates the activity surrounding a black hole.
Does Hawking’s holographic principle prove black hole evaporation?
Specifically, Hawking’s calculations indicated that black hole evaporation via Hawking radiation does not preserve information. Today, many physicists believe that the holographic principle (specifically the AdS/CFT duality) demonstrates that Hawking’s conclusion was incorrect, and that information is in fact preserved.
What are the advantages and disadvantages of a black hole?
Advantage: The size of remnant increases with the size of the initial black hole, so there is no need for an infinite number of internal states. Disadvantage: Hawking radiation must stop before the black hole reaches the Planck size, which requires a violation of semi-classical gravity at a macroscopic scale.
What happens to Hawking radiation when it enters a black hole?
From the no-hair theorem, one would expect the Hawking radiation to be completely independent of the material entering the black hole. Nevertheless, if the material entering the black hole were a pure quantum state, the transformation of that state into the mixed state of Hawking radiation would destroy information about the original quantum state.
