Question

Why do black holes emit neither radiation nor other information? The answer to this question is related to the concept of escape speed—the speed necessary for one object to escape the gravitational pull of another object. The escape speed from an object depends entirely on its mass and radius. Consider a star of a given mass. If the star remains the same mass, but decreases in radius, its escape speed will _____.

Answer 1

increase

Step-by-step explanation:

Hello! Black holes are objects whose gravitational attraction is so large that not even light can escape its surface. The escape velocity in a black hole has a value of 300,000 km / s or more. If we have an object whose mass is very concentrated in low volume, it will have a very intense gravity on its surface.
