1 Minute Speech On Black Hole In English

Good morning to everyone, I’d like to express my gratitude to the principal, the teachers, and my friends for letting me tell you about the black hole. An area of space-time known as a “black hole” is one from which nothing, not even light, can escape. The general theory of relativity states that it first appears when a significant mass bends spacetime. 

It is black because, like a perfect black body in thermodynamics, it completely absorbs all the light that strikes it and reflects none. Black holes gradually shrink because they have a temperature and produce Hawking radiation. 

They may be located with telescopes on Earth or in Earth orbit, as well as by monitoring the motion of stars or gas sucked into a black hole. Scientists have discovered evidence of supermassive black holes in the core of virtually all galaxies, including the Milky Way galaxy’s Sagittarius A* region. Thank you.
