What makes black hole so heavy even it's tiny in size?
Phobos said:A star like our sun will compact down to an object called a white dwarf which will be about the size of the planet Earth.
A white dwarf is what's left when a red giant runs out of fuel for fusion and blows away its outer layers, leaving the core behind. See red giants and white dwarfs.DB said:isnt our sun is expected to become a red giant?
Blackholes can't be seen directly, because light cannot escape them. They are detected from the X-rays that the accretion disks they form. When material falls into a black hole from a companion star, it gets heated to millions of degrees Kelvin and accelerated. The superheated materials emit X-rays, which can be detected by X-ray telescopes such as the orbiting Chandra X-ray Observatory. The star Cygnus X-1 is a strong X-ray source and is considered to be a good candidate for a black hole. Stellar winds from the companion star, blow material onto the accretion disk surrounding the black hole. As this material falls into the black hole, it emits X-rays.kiru said:Do you mean that the black hole is perfectly black?
A black hole is a region in space with such a strong gravitational pull that nothing, including light, can escape from it. It is formed when a massive star dies and its core collapses under its own weight.
The weight of a black hole is measured using its event horizon, which is the point of no return for anything that enters the black hole. The size of the event horizon is directly related to the mass of the black hole, so by measuring the size, we can determine the weight.
The weight of black holes is determined by the amount of mass that is contained within their event horizon. As more matter gets pulled into the black hole, its weight increases. The gravity of a black hole is so strong because all of its mass is concentrated into a single point, known as the singularity.
The weight of black holes has significant implications in astrophysics and our understanding of the universe. It helps us understand the evolution of galaxies, the formation of stars, and the behavior of matter in extreme conditions. It also plays a crucial role in the study of gravity and the search for a unified theory of physics.
Yes, the weight of black holes can change over time. As they continue to consume matter, their weight increases. However, the rate at which they gain weight slows down over time. Black holes can also lose weight through a process called Hawking radiation, where they emit small amounts of energy over time.
