Question

While scientists have from their theories calculated the current temperature associated with the radiation that was found everywhere when the universe became transparent, unfortunately there is no experimental way to observe this radiation today.

a. True
b. False

Answer 1

The idea that the early universe's radiation cannot be observed today is false. The cosmic microwave background radiation serves as observable evidence of the Big Bang model and has been extensively studied to understand the universe's evolution.

Step-by-step explanation:

The statement that there is no experimental way to observe the radiation from the early universe is false. The cosmic microwave background radiation (CMB) is this very remnant from a time known as the photon decoupling era, when the universe became transparent. Scientists have indeed detected and measured this feeble glow of radiation as it is present throughout the universe. It provides significant evidence supporting the Big Bang model. The CMB was first predicted by Alpher and Herman, and despite being forgotten over years, it was later rediscovered, providing strong evidence for our understanding of the evolution of the universe.

However, we have detected the feeble glow of radiation emitted at a time when the universe was a few hundred thousand years old, which provides valuable information about the early universe.
