What Occurred in the First 10^-43 Seconds After the Big Bang?

Discover what happened in the first 10^-43 seconds post-Big Bang and the dawn of the universe during the Planck Epoch.

50 views

In the first 10^-43 seconds after the Big Bang, known as the Planck Epoch, the universe was in an extremely hot and dense state. During this time, gravity separated from the other fundamental forces (electromagnetism, strong nuclear force, and weak nuclear force). This epoch marks the beginning of the universe's rapid expansion and the foundation for the formation of matter and cosmic structures that followed.

FAQs & Answers

  1. What is the Planck Epoch? The Planck Epoch is the earliest phase of the universe, lasting from the Big Bang until about 10^-43 seconds, characterized by extreme temperatures and densities.
  2. What fundamental forces emerged after the Big Bang? After the Big Bang, gravity separated from the other forces like electromagnetism, strong nuclear force, and weak nuclear force.
  3. How did the universe expand after the Big Bang? After the Planck Epoch, the universe underwent rapid expansion, leading to the cooling and formation of matter.
