If there are other stars orbiting a black hole, their orbits can be usual to determine the black hole’s mass and location.
😊By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses may form.
😊In numerous ways, a black hole acts like an ideal black body, as it reflects no light.
😊The theory of general relativity predicts a sufficiently compact mass can deform spacetime to form a black hole.
😊 A black hole is a region of spacetime where gravity is so strong nothing—no particles or even electromagnetic radiation such as light—can escape from it.
😊Matter falls onto a black hole can form an external accretion disk heated by friction, forming quasars, some of the brightest objects in the universe.
😊Stars passing too close to a supermassive black hole can be shred into streamers shine very brightly before being “swallowed.” Black holes of stellar mass are expected to form when very massive stars collapse at the end of their life cycle.
😊The presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as visible light.
😊As of December 2018, eleven gravitational wave events own been observed originated from ten merging black holes.
😊After a black hole has formed, it can continue to grow by absorbing mass from its surroundings.
😊This temperature is on the arrangement of billionths of a kelvin in support of black holes of stellar mass, making it essentially impossible to observe.
😊There is consensus supermassive black holes exist in the centers of largest galaxies.
😊Objects whose gravitational fields are too strong in support of light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace.
😊The discovery of neutron stars by Jocelyn Bell Burnell in 1967 sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality.
😊The boundary of the region from which no escape is possible is called the event horizon.
