Theories about black holes
Webb1 juli 2024 · A central law for black holes predicts that the area of their event horizons — the boundary beyond which nothing can ever escape — should never shrink. This law is Hawking’s area theorem, named after physicist Stephen Hawking, who derived the … Webb13 okt. 2024 · Learn more here. Black holes are regions in space where an enormous amount of mass is packed into a tiny volume. This creates a gravitational pull so strong that not even light can escape. They are created when giant stars collapse, and perhaps by other methods that are still unknown.

Webb12 apr. 2024 · Black hole echo is an important observable that can help us better understand gravitational theories. The non-linear electrodynamic black holes can admit multi-horizon, and the destruction of outer horizons does not violate the weak cosmic censorship, which leads to the multi-peak effective potential for the scalar perturbations … WebbBlack holes are some of the most fascinating and mind-bending objects in the cosmos. The very thing that characterizes a black hole also makes it hard to study: its intense gravity. All the mass in a black hole is concentrated in a tiny region, surrounded by a boundary called the “event horizon”. Nothing that crosses that boundary can return to the …
Webb10 apr. 2024 · Black holes were once thought to be only a mathematical curiosity. They were bizarre beasts that squashed gobs of matter into infinitely dense abysses. But bit by bit, astronomers tallied up evidence for black holes’ existence. They puzzled over where these behemoths live and how they gulp down matter.

WebbAstrophysical theory allows black holes to come in many sizes, and the size of a black hole is simply proportional to its mass. Thus, a black hole with the mass of the Earth would be about an inch across, one with the mass of the Sun would be a few miles across, and one with the total mass of the Milky Way Galaxy would be about a light-year ...
