Black Holes Made By Omar Alaa & Mohammed Nabil What are Black Holes? • • Black holes are incredibly compact objects with extremely high gravitational fields in which even light (with an approximate speed of 3x108 m/s) cannot escape, leading the dark holes to look black at all wavelengths of the electromagnetic spectrum. There are various sorts of black holes. Small stellar black holes form near the end of the life cycle of a big star. When the star's fuel runs exhausted, the centre of the star can collapse under its own weight. Another type of black hole is a supermassive black hole, which is millions to billions of times more massive than the Sun. BUT HOW ARE BLACK HOLES CONNECTED TO CIRCULAR MOTION AND UNIVERSIAL GRAVITY? 2 BUT HOW ARE BLACK HOLES CONNECTED TO CIRCULAR MOTION AND UNIVERSIAL GRAVITY? • Recent publications have investigated the circular arc (element space) of neutral particles on an equatorial plane surrounding a rotating black hole. • They discovered the equation of circular photon orbit by combining certain equations (motion of linear gravity) with the circular geodesics of null-like particles • A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. 3 How the law of universal gravitation explains the formation of black hole? A black hole is like another body from a-far, and Newton's principles of gravity apply. Objects will feel the gravitational attraction of a black hole, and they will be able to orbit around it. Time will slow down, and there will be gravitational tidal effects. If Black Holes Are "Black," How Do Scientists Know They Are There? 4 • A black hole cannot be seen because immense gravity draws all light into the black hole's center. However, astronomers can observe how the black hole's enormous gravity affects the stars and gas in its vicinity. Scientists can study stars to see if they are circling or travelling around a black hole. When a black hole and a star collide, high-energy light is produced. This type of light is not visible to human eyes. To observe the high-energy light, scientists employ satellites and telescopes in orbit. 5 To conclude our small decent project, I'd like you to watch this small video, which highlights everything we've stated throughout the project and was created by a YouTube channel Which I do totally like that they do teaches people science in a simple and exciting manner.
