How Scientists Formulated the Big Bang Theory: Key Discoveries Explained

Explore how scientists developed the Big Bang Theory through groundbreaking observations and discoveries, including Hubble's findings.

37 views

Scientists developed the Big Bang Theory by observing the expanding universe, majorly supported by Edwin Hubble's discovery that galaxies are moving away from us. The theory is bolstered by the cosmic microwave background radiation, discovered by Penzias and Wilson, which is considered the afterglow of the Big Bang. Additionally, the abundance of light elements like hydrogen and helium in the universe aligns with predictions, providing further validation.

FAQs & Answers

  1. What is the significance of Edwin Hubble's discoveries? Edwin Hubble's discoveries showed that galaxies are moving away, providing critical support for the Big Bang Theory.
  2. What is cosmic microwave background radiation? Cosmic microwave background radiation is the afterglow of the Big Bang, acting as evidence of the universe's early hot and dense state.
  3. How do light elements support the Big Bang Theory? The abundance of light elements such as hydrogen and helium matches predictions made by the Big Bang Theory, reinforcing its validity.
  4. What are some other theories about the universe's origin? Other theories include the Steady State Theory and various quantum gravity proposals, but the Big Bang remains the most widely accepted.
