With the help of which one of the following waves big bang theory are proved?
Answers
Answer:
Cosmic microwave background radiation
Cosmic microwave background radiation
In 1964, Arno Penzias and Robert Wilson serendipitously discovered the cosmic background radiation, an omnidirectional signal in the microwave band. Their discovery provided substantial confirmation of the big-bang predictions by Alpher, Herman and Gamow around 1950.
Answer:
CMB
The cosmic microwave background (CMB, CMBR)
Hubble's law and the expansion of space
Explanation
Crucially, the theory is compatible with Hubble's law – the observation that the farther away galaxies are, the faster they are moving away from Earth. Extrapolating this cosmic expansion backwards in time using the known laws of physics, the theory describes a high density state preceded by a singularity in which space and time lose meaning.[5] There is no evidence of any phenomena prior to the singularity. Detailed measurements of the expansion rate of the universe place the Big Bang at around 13.8 billion years ago, which is thus considered the age of the universe.
The Big Bang theory is a cosmological model of the observable universe from the earliest known periods through its subsequent large-scale evolution.The model describes how the universe expanded from an initial state of extremely high density and high temperature,and offers a comprehensive explanation for a broad range of observed phenomena, including the abundance of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure.
