Study Notes
Big Bang Theory
- Space and time are believed to have emerged together approximately 13.8 billion years ago during the Big Bang event.
Observable Universe
- The approximate diameter of the observable universe is about 93 billion light-years. This expanse encompasses all matter and energy that can be observed from Earth.
Heliocentric Model
- The heliocentric model, positioning the Sun at the center of the Solar System, was developed by Nicolaus Copernicus. This revolutionary idea changed the understanding of the cosmos.
Ancient Cosmological Models
- Some of the earliest cosmological models were developed by ancient philosophers like Aristotle and Ptolemy. Their work laid foundational concepts in cosmology.
Isaac Newton's Contributions
- Isaac Newton built upon the earlier works of astronomers such as Johannes Kepler and Galileo Galilei when formulating the law of universal gravitation, which describes the attraction between masses.
