By nature, black holes do not themselves emit any electromagnetic radiation other than the hypothetical Hawking radiation, so astrophysicists searching for black holes must generally rely on indirect observations. For example, a black hole's existence can sometimes be inferred by observing its gravitational influence on its surroundings.

We cannot see anything from inside there, so we have no idea how much smaller the actual "object" involved must be, or even whether there is even an object at all, and the self-similarity of black hole geometries means that it provides a useful ...
WebThis radius depends on the mass of the black hole. For a black hole as massive as the Sun, the radius is about two miles (3 km). For every extra solar mass, the radius increases by two miles. This radius enfolds the singularity in a zone of blackness - in other words, it makes a black hole black. WebProblem 4 - A supermassive black hole has 100 million times the mass of the sun (1.9 x 1033 grams), and an event horizon radius of 295 million kilometers. What would be the tidal acceleration across a d=2 meter human at a distance of 100 kilometers from the event horizon of the supermassive black hole? Answer: a = 2 x (6.67 x 10-8) x (1.9 x 10 41
WebSep 28, 2012 · Scientists Measure the Radius of a Black Hole at the Center of M87. This image, created using computer models, shows how the extreme gravity of the black hole in M87 distorts the appearance of the jet near the event horizon. Part of the radiation from the jet is bent by gravity into a ring that is known as the ‘shadow’ of the black hole.
