Respected Principal, teachers and my dear friends, a wonderful morning to all of you. Today on this special occasion, I would like to speak some words on the topic- Black Holes.
Black holes are formed when stars, much larger than our own sun, collapse. This creates an entity of extremely high mass and density which results in inconceivable gravity. The gravity of black holes is in fact so much that even light cannot escape them. This is why they are called black holes, devoid of any light.
There has been an immense amount of research on blach holes in recent years, and yet we know very little about them. The great scientist Stephen Hawking has contributed the most to the study of black holes. His famous equation called the Hawking Radiation equation explains the phenomenon of black holes.
To conclude, black holes are indeed fascinating things! Thank you for listening to me so attentively.
