Why Einstein Initially Rejected the Big Bang Theory

Discover why Einstein favored a static universe over the Big Bang theory and how his views changed with new cosmic evidence.

6 views

Einstein initially did not believe in the Big Bang theory because he favored a static universe model. He introduced the cosmological constant to support this idea. However, later discoveries like redshift in distant galaxies led him to discard the static model. He eventually accepted an expanding universe theory, acknowledging his earlier mistake.

FAQs & Answers

  1. What is the Big Bang theory? The Big Bang theory proposes that the universe began from a singular, extremely hot and dense point approximately 13.8 billion years ago.
  2. What led to Einstein's change of belief about the universe? Discoveries such as redshift observations in distant galaxies prompted Einstein to re-evaluate his static universe model and accept an expanding universe.
  3. What is Einstein's cosmological constant? Einstein introduced the cosmological constant as a force to maintain a static universe, which he later deemed unnecessary after the acceptance of an expanding universe.
  4. How did Einstein impact modern cosmology? Einstein's theories laid the groundwork for contemporary cosmological concepts, including the expansion of the universe and the formulation of general relativity.
