Study Notes
Understanding the Big Bang Theory and the Composition of the Universe
- The Big Bang Theory is the most widely accepted theory on the origin of the universe, which explains that the universe underwent sudden inflation from a singularity to its current state.
- Edwin Hubble proposed the idea that galaxies are moving away from each other and this became evidence for the expanding universe.
- Georges Lemaitre was the first proponent to explain the Big Bang based on the "primeval atom," which is now known as the singularity.
- George Gamow formulated the modern Big Bang theory, which explains the distribution of chemical elements throughout the universe.
- Baryonic matter, which consists of protons, electrons, and neutrons, makes up only 5% of the universe's composition.
- Dark matter, which makes up 27% of the universe, exerts gravity but does not emit or absorb light, and its existence is necessary for the formation of large galaxies.
- Dark energy, which holds 68% of the universe, can explain the accelerating expansion of the universe but is not well understood.
- The composition of the universe is mostly unknown, with only 5% being ordinary matter and less than 1% being stars.
- The cosmic microwave background radiation is evidence for the Big Bang theory, as it provides a snapshot of the universe when it was only 380,000 years old.
- The abundance of light elements such as hydrogen and helium in the universe is also evidence for the Big Bang theory.
- The redshift of distant galaxies, which indicates that they are moving away from us, is further evidence for the expanding universe and supports the Big Bang theory.
- Scientists continue to study the Big Bang theory and the composition of the universe, seeking to better understand the mysteries of dark matter and dark energy.
