Astronomy: The Universe at a Glance (Chaisson/McMillan)
Chapter 15 Cosmology and the Universe
1) An infinite universe is one of the assumptions of the cosmological principle.
Answer: FALSE
Diff: 1
Section Ref: 15.1
2) The cosmological redshift is a direct measure of the expansion of the universe, thus
independent of direction.
Answer: TRUE
Diff: 1
Section Ref: 15.2
3) The Hubble constant divided into the number one gives a rough estimate for the age of the
universe, or the "Hubble Time."
Answer: TRUE
Diff: 1
Section Ref: 15.2
4) The cosmological redshift is actually not a velocity at all, but a measure of the expansion of
space-time.
Answer: TRUE
Diff: 2
Section Ref: 15.2
5) The Big Bang was an expansion of matter into empty space.
Answer: FALSE
Diff: 2
Section Ref: 15.2
6) The low density universe is an open one, with expansion continuing forever.
Answer: TRUE
Diff: 1
Section Ref: 15.2
7) The universe has been expanding at the same rate since its formation.
Answer: FALSE
Diff: 1
Section Ref: 15.3
8) The fate or future of the universe depends only on the total number of galaxies and quasars.
Answer: FALSE
Diff: 1
Section Ref: 15.3
1
, 9) The cosmic microwave background is the total of all the radio emissions from all the galaxies
and quasars in the universe.
Answer: FALSE
Diff: 1
Section Ref: 15.4
10) Not taking dark energy into account, we seem to live now in a matter dominated universe,
since the observed matter density exceeds the observed energy density.
Answer: TRUE
Diff: 1
Section Ref: 15.4
11) Deuterium was made only in primordial nucleosynthesis, since stars destroy it.
Answer: TRUE
Diff: 2
Section Ref: 15.5
12) Primordial nucleosynthesis refers to the Big Bang making all elements up to iron.
Answer: FALSE
Diff: 2
Section Ref: 15.5
13) At decoupling, the electrons and protons were made from neutron decay.
Answer: FALSE
Diff: 2
Section Ref: 15.5
14) Decoupling refers to interactions between matter and antimatter at the end of the Radiation
Era.
Answer: FALSE
Diff: 3
Section Ref: 15.5
15) The flatness problem is the fact that the observed density of matter is unexpectedly different
from the critical density predicted by the inflationary epoch.
Answer: FALSE
Diff: 3
Section Ref: 15.6
16) The universe expanded by a factor of 1050 during inflation, when the strong force separated
from the electromagnetic and weak nuclear forces.
Answer: TRUE
Diff: 3
Section Ref: 15.6
