SPACE EXPLORATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Radio astronomers Arno Penzias and Robert Wilson discovered a microwave signal during their research in 1964. The microwaves were uniform and coming from all directions in the sky. The phenomenon known as Cosmic Microwave Background (CMB) provided evidence that the universe was once very hot and dense.How did CMB contribute to the big bang theory?
A
CMB confirmed how matter expanded during the big bang.
B
CMB was the magnetic field that was created during the big bang.
C
CMB was a reflection of the thermal energy generated during the big bang.
D
CMB represented energy trails from moving matter that began with the big bang.
Explanation: 

Detailed explanation-1: -Penzias and Wilson had spotted the CMB, the predicted thermal echo of the universe’s explosive birth. The landmark find put the Big Bang theory on solid ground, suggesting that the cosmos did indeed grow from a tiny seed-a single point-about 13.8 billion years ago.

Detailed explanation-2: -Dicke had begun looking for evidence to support his theory when Penzias and Wilson got in touch with his laboratory. He visited Bell Labs and confirmed that the mysterious radio signal was indeed the cosmic background radiation-proof of the Big Bang.

Detailed explanation-3: -Bell Labs’ Horn Antenna in Crawford Hill, NJ-In 1964 while using the Horn Antenna, Penzias and Wilson stumbled on the microwave background radiation that permeates the universe.
