The second major piece of evidence supporting the Big Bang theory was the discovery of cosmic microwave background radiation (CMB), which was made by Arno Penzias and Robert Wilson in 1965. This faint radiation, uniform across the universe, is considered a remnant of the hot, dense state of the early universe. Their discovery provided crucial support for the Big Bang model, confirming predictions made by cosmologists about the early universe's conditions.

Which theory is supported by the evidence of cosmic microwave backround radiation?

The evidence of cosmic microwave background radiation supports the Big Bang theory.


How has molecular evidence affected our understanding of modern evolutionary theory?

It largely supports anatomical evidence and provides more detailed information for specific relationships


Who are the two scientists that discovered the 2nd piece of evidence of the Big Bang Theory?

The two scientists who discovered the second piece of evidence for the Big Bang Theory are Arno Penzias and Robert Wilson. In 1965, they accidentally detected cosmic microwave background radiation (CMB) while working on a microwave radio receiver at Bell Labs. This discovery provided strong evidence for the Big Bang Theory, as the CMB is considered the afterglow of the hot, dense state of the early universe. Their work earned them the Nobel Prize in Physics in 1978.


What evidence was discovered in 1965 that supports the bib bang theory?

The Cosmic Microwave Background, discovered (almost by accident) in 1964, perfectly matches what the Big Bang Theory predicted. No other hypothesis can begin to explain it, beyond saying "Well, it's just there and I have no explanation why."


Why is the existence of Pangaea a belief rather than a fact?

The existence of Pangaea is a scientific theory supported by evidence such as the fit of the continents, geological similarities, and fossil distributions. While overwhelming evidence supports the theory, it is still technically a hypothesis because we cannot directly observe the movement of the continents over millions of years.
