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
BSSSSS).
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) The measurement of redshifts that show galaxies appear to be moving away from each other and the Universe is expanding.
D) Observing that galaxies at very large distances look identical to those in the nearby universe.
E) An observation that some globular clusters show M-type stars that have evolved off the main sequence.
Explanation / Answer
A) The measurement of the microwave background radiation---------(B) such an uniformaty comes when universe was started from a unifrom dense object i.e. Big Bang.
B) A measurement that shows the density of the Universe is close to the critical density--------(B) The simplest version of the inflationary theory, an extension of the Big Bang theory, predicts that the density of the universe is very close to the critical density, and that the geometry of the universe is flat, like a sheet of paper.
C) The measurement of redshifts that show galaxies appear to be moving away from each other and the Universe is expanding-----------(S)
(D) Observing that galaxies at very large distances look identical to those in the nearby universe--------(B)
E) An observation that some globular clusters show M-type stars that have evolved off the main sequence------(B)
