How is a black hole possible
Web23 jun. 2024 · Einstein said that mass and energy are equivalent – you can turn mass into energy and energy into mass – so very high energy particles smashing together could potentially lead to the creation of a black hole. However, the energy required for this would be the equivalent to taking the mass of a mountain range and converting it into energy. Web8 apr. 2024 · The supermassive black hole, which is likely around 20 million times the mass of our Sun, is zooming through the universe at about 3.5 million miles per hour. …

If the astronaut were to look out from inside a black hole, they would see the universe behind them moving rapidly. Due to dilation—a shift in one’s perspective of time due to extreme gravitational forces—it is speculated that the astronaut may even be able to see future events within the universe.
A 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. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The … Meer weergeven 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 … Meer weergeven By nature, black holes do not themselves emit any electromagnetic radiation other than the hypothetical Hawking radiation, so astrophysicists … Meer weergeven Entropy and thermodynamics In 1971, Hawking showed under general conditions that the total area of the event horizons of any collection of classical black holes can never decrease, even if they collide and merge. This result, now known as the Meer weergeven The no-hair theorem postulates that, once it achieves a stable condition after formation, a black hole has only three independent … Meer weergeven Given the bizarre character of black holes, it was long questioned whether such objects could actually exist in nature or whether … Meer weergeven The evidence for stellar black holes strongly relies on the existence of an upper limit for the mass of a neutron star.
