6. [4pt] Another explanation for the Universe it the Steady State Hypothesis. The Steady State Hypothesis says that the Universe has always existed and is infinite in extent. Which of the following support the Big Bang Theory and which support the Steady State Model (Select B-Big Bang Theory, S-Steady State Model, If the first is B and the rest S, enter A) The measurement of the microwave background radiation B) A measurement that shows the density of the Universe is close to the critical density. C) An observation that some globular clusters show M-type stars that have evolved off the main sequence. D) Observing that galaxies at very large distances look identical to those in the nearby universe E) The measurement of redshifts that show galaxies appear to be moving away from each other and the Universe is expanding.Explanation / Answer
(A) B
The Big Bang theory suggess that the universe was too hot and as it expands the gases cools. So the universe muxt be full of radiation i.e, the remnant heat left over because of Big Bang, which is known as the cosmic microwave background
(B) B
The current density of the universe is found to be very close to the critical value.This is related to the flatness problem related to big bang theory
(C) B
From the results of constrain cosmological parameters,it is required to add to the ages a time which is according to the time between the Big Bang and globular clusters formation in galaxy.
(D) B
