Web8 de abr. de 2024 · However, a black hole was simply a theoretical object for decades. No one was sure if they really existed or if it was something that just went weird with the equations once the mass reached a particular point. The debate ended in 1971 with the discovery of Cygnus X-1, the first black hole which was discovered. WebIn September 2024, a report by James Unwin and Jakub Scholtz proposed the possibility of a primordial black hole (PBH) with mass 5–15 MEarth (Earth masses), about the diameter of a tennis ball, existing in the extended Kuiper Belt to explain the orbital anomalies that are theorized to be the result of a 9th planet in the solar system.

Black Holes

WebCygnus X-1 is a so-called stellar-mass black hole, a class of black holes that comes from the collapse of a massive star. The black hole is in close orbit with a massive, blue companion star.
