Mystery Of The Black Holes (#Final).pptx

Mystery of black hole

1. THE MYSTERY OF BLACK HOLE Understanding Gravity And Space-Time

2. What Is Black Hole? A region in space with a gravitational pull so strong that nothing, not even light, can escape. Formed when massive stars collapse at the end of their life cycle.

3. What is gravity? Gravity is the force that attracts two bodies towards each other. In black holes, gravity is extremely strong due to their massive density. 8/24/2024 3

4. SPACE-TIME CONCEPT Space-time is a four-dimensional fabric that can be warped by massive objects like black holes, according to Einstein’s general theory of relativity 8/24/2024 4

5. HOW BLACK-HOLES ARE FORMED? Black holes are formed when massive stars run out of nuclear fuel and collapse under their own gravity. 8/24/2024 5

6. TYPES OF BLACK-HOLES Stellar Black Holes: Formed from collapsing stars. Supermassive Black Holes: Found at the center of galaxies, millions to billions of times more massive than the Sun. Primordial Black Holes: Hypothetical, formed in the early universe. 8/24/2024 6

8. INTRODUCTION OF HAWKING RADIATION A theoretical concept proposed by Stephen Hawking in 1974. Black holes can emit radiation due to quantum effects near the event horizon. Over time, this radiation causes the black hole to lose mass and potentially evaporate completely. 8/24/2024 8

9. The First Image of a Black Hole In 2019, the Event Horizon Telescope captured the first image of a black hole in the M87 galaxy, 55 million light-years away. 8/24/2024 9

10. QUESTIONS Topic of the presentation? Answer : Black Holes What collapses to form a black hole? Answer : Star What can't escape a black hole? Answer : Light What force attracts two bodies? Answer : Gravity 8/24/2024 10
