If Planck length is the smallest size, does that mean a black hole would get compressed down to the Planck scale, but no further or can the black hole really have zero size like an electron?
The size of a black hole varies depending on its mass. The more mass a black hole has, the larger its event horizon, which is the point of no return for anything that enters the black hole's gravitational pull. The event horizon can range from a few kilometers to billions of kilometers in diameter.
The size of a black hole is typically measured by its event horizon, which can be calculated using the black hole's mass and its Schwarzschild radius. The Schwarzschild radius is the distance from the center of the black hole where the escape velocity equals the speed of light.
Yes, the size of a black hole can change over time. As a black hole consumes matter, its mass and event horizon will increase. Additionally, black holes can merge with other black holes, resulting in a larger black hole.
There is no known size limit for black holes. As long as a black hole continues to consume matter, its size can continue to increase. However, there is a theoretical limit known as the Eddington limit, which is the maximum amount of mass a black hole can have before its radiation outflow overcomes its gravitational pull.
No, black holes can vary in size depending on their mass. There are three main types of black holes: stellar black holes, intermediate black holes, and supermassive black holes. Stellar black holes can range from a few solar masses to tens of solar masses, while supermassive black holes can have masses equivalent to billions of suns.
