Question

Quizplus · Accepted Answer

The cosmic microwave radiation, also known as the cosmic microwave background radiation, is considered the strongest experimental evidence supporting the Big Bang theory. This radiation was discovered in 1964 and is believed to be the remnant heat left over from the Big Bang itself. The abundance of hydrogen, helium, and lithium, known as the primordial elements, also support the Big Bang theory as they were formed in the early universe in the manner predicted by the theory. Together, the observation of the cosmic microwave radiation and the abundance of these elements provide strong evidence for the Big Bang theory. Universal contraction and creationism are not supported by any direct evidence.
