Answer 1

The cosmic radiation that originated from the Big Bang was detected through radio telescopes observing cosmic microwave background radiation. The Big Bang Theory states that the universe is constantly expanding from a singular point. The key events of the Radiation Era include nucleosynthesis of light elements and the formation of cosmic microwave background radiation.

The cosmic radiation that originated from the Big Bang was detected through radio telescopes observing cosmic microwave background radiation. Scientists discovered a faint microwave radiation coming from all directions in the universe, which provided evidence for the Big Bang Theory. This radiation is known as the cosmic microwave background (CMB) radiation.

The Big Bang Theory states that the universe is constantly expanding from a singular point. It explains the origin and evolution of the universe, starting from an extremely hot and dense state.

The Radiation Era was a period of the universe's history when radiation dominated. Key events during this era included the nucleosynthesis of light elements (such as hydrogen and helium) and the formation of cosmic microwave background radiation.

The Matter Era followed the Radiation Era, and it was a period when matter started to dominate in the universe. Key events during this era included the clustering of matter into galaxies and galaxy clusters and the universe becoming transparent to light.
