Study Notes
The Big Bang Theory
- Most accepted theory explaining the universe's expansion from a singular explosion.
- Originated from a single particle at a specific point in time.
Edwin Hubble's Contributions
- In the 1920s, American Astronomer Edwin Hubble formulated Hubble's Law.
- This law enabled calculations of how long galaxies have been moving apart.
- Provided essential estimates for the timing of the Big Bang and the universe's age.
Georges Lemaitre's Hypothesis
- In the 1930s, Belgian Cosmologist Georges Lemaitre proposed the universe's origin occurred 13.7 billion years ago.
- Suggested that the cause of the Big Bang is currently unknown.
Formation of Space, Matter, and Energy
- Hypothesis describes the emergence of space, matter, and energy from an extremely small and dense hot ball.
- This hot ball continuously emitted radiation, driving the events leading to the Big Bang.
- High-density conditions led to subatomic particles and antiparticles annihilating each other.
- Spontaneous production and destruction of matter occurred in these extreme environments.
