" ... First off, this visualization is not for real particles, but virtual ones. They are calculational tools only, not physically observable entities. Second, the Hawking radiation that leaves a black hole is almost exclusively photons, not matter or antimatter particles. And third, most of the Hawking radiation doesn't come from the edge of the event horizon, but from a very large region surrounding the black hole. If you must adhere to the particle-antiparticle pairs explanation, it's better to try and view it as a series of four types of pairs: ... "
" ... For centuries, the laws of physics seemed completely deterministic. If you knew where every particle was, how fast it was moving, and what the forces were between them at any one instant, you could know exactly where they'd be and what they'd be doing at any point in the future. From Newton to Maxwell, the rules that governed the Universe had no built-in, inherent uncertainty to them in any form. Your only limits arose from your limited knowledge, measurements, and calculational power. ... "
" ... The major problem with Hawking's explanation of his own theory is that he takes a calculational tool — the idea of virtual particles — and treats that tool as though it's equivalent to physical reality. In reality, what's happening is that the curved space around the black hole is constantly emitting radiation due to the curvature gradient around it, and that the energy is coming from the black hole itself, causing its event horizon to slowly shrink over time. ... "
" ... When most of us think about the Universe, we think about the material objects that are out there across the great cosmic distances. Matter collapses under its own gravity to form cosmic structures like galaxies, gas clouds contract to form stars and planets; stars emit light by burning their fuel through nuclear fusion; that light travels throughout the Universe, illuminating anything it comes into contact with. But there’s more to the Universe than the objects within it. There’s also the fabric of spacetime, which has its own set of rules that it plays by: General Relativity. The fabric of spacetime is curved by the presence of matter and energy, and curved spacetime itself tells matter and energy how to move through it. But what, exactly, is spacetime, and is it a “real” thing, or just a calculational tool? That’s the inquiry of Dave Drews, who wants to know: ... "
