WebOct 15, 2024 · Recently, the first ever image of a black hole has been captured by a network of eight radio telescopes around the world . These discoveries open up hope to directly test various black hole theories from astronomical aspects. One remarkable property of classical black holes is the famous no hair theorem [2,3,4,5,6,7,8,9]. WebA black hole is a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape its event horizon.
