How do they work, like I’m just confused I don’t understand anything about them
In: Physics
To understand black holes, you must first understand the concept of gravity. In the 1920s, Albert Einstein formulated his general theory of relativity, which postulates that gravity is not a force that propagates through space, but a warping or curvature of space-time. The greater the mass of an object, the greater the curvature in space time and the greater the gravitational force.
A black hole is the result of the curving of space time by a huge mass. The gravity is so strong because matter has been squeezed into a tiny space. Stellar black holes are formed when center of a very big star falls in upon itself, or collapses.
Around a black hole there is a position of no return, called the event horizon. A black hole it absorbs all the light that hits it, reflecting nothing. A black hole is found by its interaction with matter and gas. Scientists study how strongly gravity affects the stars and gas in a region to work out the presence of a black hole.
