Your category is the answer, that thing is black hole


Is so massive that its gravity does not even let light escape?

The object you are describing is a black hole. It is a region in space where gravity is so strong that not even light can escape from it, hence why it appears completely black and invisible to outside observers.


Is a black hole so massive that its gravity doen not even let escape?

Yes, black holes are so massive and dense that their gravity is immensely strong. This gravity is often strong enough to prevent even light from escaping, which is why black holes are known as "black" because they do not emit any visible light.


How big is black hole?

Before you can answer 'how big is a black hole?', you have to understand exactly what a black hole is. A black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. That definition leads you to wonder slightly about gravity. If, for some reason, you throw a rock straight up into the air it will rise for a while, but eventually the acceleration due to the planet's gravity will make it start to fall down again. If the acceleration is enough, you could make it escape the planet's gravity entirely. It would keep on rising forever. The speed with which you need to throw the rock in order that it just barely escapes the planet's gravity is called the "escape velocity." As you would expect, the escape velocity depends on the mass of the planet: if the planet is extremely massive, then its gravity is very strong, and the escape velocity is high. A lighter planet would have a smaller escape velocity. The escape velocity also depends on how far you are from the planet's center: the closer you are, the higher the escape velocity. The Earth's escape velocity is 11.2 kilometers per second and the Moon's is only 2.4 kilometers per second. After taking those two facts into consideration, look at a black hole. It is so massive that light does not travel fast enough to escape its gravity. Since nothing known travels faster than the speed of light, nothing can escape a black hole. Now, back to the original question 'how big is a black hole?'. There are many different ways to describe how big something is. Let's just look at much mass it has and how much space it takes up. There is no limit(in principle) to how much or how little mass a black hole can have. In theory, any amount of mass at all can be made to form a black hole if you compress it to the right density. Most of the black holes were produced by the deaths of massive stars, so scientists believe those black holes weigh about as much as a massive star. A typical mass for such a black hole would be about 10 times the mass of the Sun, or about 1031 kilograms. Astronomers also suspect that many galaxies harbor extremely massive black holes at their centers. These are thought to weigh about a million solar masses. the more massive a black hole is, the more space it takes up. In fact, the Schwarzschild radius(radius of the event horizon) and the mass are directly proportional to one another: if one black hole weighs ten times as much as another, its radius is ten times as large. A black hole with a mass equal to that of the Sun would have a radius of 3 kilometers. So a typical 10-solar-mass black hole would have a radius of 30 kilometers, and a million-solar-mass black hole at the center of a galaxy would have a radius of 3 million kilometers. Whether you measure by mass or space taken up, black holes can be some of the largest objects in the universe.


Why does light, which is massless, still experience the effects of gravity?

Light, despite being massless, experiences the effects of gravity because gravity affects all forms of energy, including light. Gravity bends the path of light, causing it to be attracted towards massive objects like stars and planets. This phenomenon is known as gravitational lensing.

How does the force of gravity affect the object?

The force of gravity is responsible for pulling objects toward the center of a massive body, like the Earth. It gives objects weight and causes them to fall toward the ground if not supported. The force of gravity also influences the trajectories of objects in motion, such as planets orbiting the sun.

What are some astronomical terms and their meanings?

A black hole is a collapsed star that does not let light escape. A nebula is a mass of gas and dust that may collapse to form a star. A red giant is a star that has expanded and cooled. A white dwarf is an old, dense, cool star.
