Two black holes of a previously unknown type have been discovered at a record-breaking distance from Earth. The discovery was made with the help of the Gaia space telescope. Astrometry is a method used to determine the … WebbBlack holes are categorized into four (4) types. The first is the supermassive black hole or SMBH. This is the largest type amounting to an unmeasurable amount of solar masses. This is usually found at the center of the largest galaxies in space. In our solar system, the SMBH is located at Sagittarius A*.
WebbThe colliding black holes that caused the recently discovered gravitational waves were considerably lighter. Like black holes, gravitational waves existed only as calculations from Einstein’s general theory of relativity, before being captured for the first time in the autumn of 2015, by the LIGO detector in the USA (Nobel Prize in Physics, 2024).

The idea of a body so big that even light could not escape was briefly proposed by English astronomical pioneer and clergyman John Michell in a letter published in November 1784. Michell's simplistic calculations assumed such a body might have the same density as the Sun, and concluded that one would form when a star's diameter exceeds the Sun's by a factor of 500, and its surface escape v… mild equator concertsWebb11 nov. 2024 · Who discovered wormholes? ...
