Before Hawking, black holes were considered the Universe’s most mysterious garbage collectors. It was once believed that nothing could escape the immense gravitational pull of one of these objects; they’re so dense that they even pull in light. But Hawking found that, in fact, some...
How did Stephen Hawking discover black holes? How are electromagnetic waves generated? How were neutrinos discovered? How do circular particle accelerators work? How does Hawking radiation escape a black hole? How are quantum dots made? What is the theory of spacetime and black holes? How do par...

The expansion of the universe does have some important effects, of course. The light that we see today as the cosmic microwave background started out as gamma rays, being radiated from the omnipresent, ultra-hot gases of the young universe, but they got stretch ou...
When that happens, there is no black hole horizon any more, and all information trapped inside the black hole can escape. In this case, the information paradox would be solved; the information would simply be re-emitted into the universe. "The black hole has a huge remnant — a Planck ...
As for their first shot at Mars, the Chinese have been thwarted by the hoodoo on Russian missions to the Red Planet. Yinghuo-1 (“Shining Planet”) rode piggyback on the Russian Phobos-Grunt spacecraft launched from Baikonur on 8 November last. The pair failed to escape from Earth orbit ...
Though a person or even an atomcannot escape a black hole, physicists believe that the universe does not destroy information, which means that, in principle, information sucked into a black hole could be spit back out. (This requirement stems from the fact that most physicists believe the laws...

During the expanding phase we need to include Ω Λ ΩΛ in the dynamics because the BH Event Horizon r S 𝑟𝑆 forbids anything to escape. This appears in the action of GR as a Gibbons-Hawking-York (GHY) boundary term [82,83,84], which is equivalent to a Λ Λ term when the ...
The application of Hawking radiation is another possible way to reach optimal solution near the black hole, inside the event horizon. Hawking verified that object can escape from a black hole and Energies 2018, 11, 1833 13 of 25 hole. Using this idea, it is possible to change the position...
