Study Notes
Black Holes
- Black holes are real, not just science fiction
- They are incredibly dense objects, with gravity so strong that not even light can escape
- Black holes form from the collapse of massive stars
- Black holes can lose energy and evaporate over extremely long timescales (Hawking radiation)
Hawking Radiation
- Proposed by Stephen Hawking
- Explains how black holes emit energy and particles
- Results from quantum effects near a black hole's event horizon
- This process causes black holes to slowly shrink and eventually disappear
Roger Penrose
- British mathematician and theoretical physicist
- Contributed to understanding black holes and the Big Bang
- Developed twistor theory and Penrose diagrams, techniques for visualizing gravity's effects
Singularities
- A point in spacetime where the density and gravity of an object become infinite.
- This represents the extreme conditions at the center of a black hole.
- The beginning of the universe could have started from a singularity.
Fame and Recognition for Hawking
- Stephen Hawking was appointed Lucasian Professor of Mathematics at Cambridge University
- He wrote popular science books, most notably A Brief History of Time
- Awarded the Breakthrough Prize in Fundamental Physics
