Question A7
State three pieces of evidence that support the idea that the Universe began in a hot Big Bang,
and explain how each piece of evidence supports the hot Big Bang model. Describe the ob-
servational evidence that supports the idea that the Universe is pervaded by Dark Energy, and
explain why each piece of evidence you cite supports the Dark Energy model.
Which of the following is an INCORRECT statement regarding the expanding universe theory?
A. Scientists were able to observe that all galaxies and star clusters are moving away from Earth because of the shift of the wavelength to the blue part of the visible spectrum.
B. Slipher from 1912 to 1914 studied the electromagnetic radiation of nearby spiral galaxies where he observed that wavelengths of yellow lines appear to be a little orange.
C. More recent observation using powerful telescopes confirm that frequency of light from nearby galaxies and star clusters decreases as it is observed here on Earth.
D. From the amount of Doppler shift, astronomers are able to compute for the speeds and determine the direction of the motion of nearby galaxies and star clusters.
How does the age of the universe relate to the Hubble constant?
a.
The smaller the constant, the older the universe.
b.
The larger the constant, the older the universe.
c.
The Hubble constant is the age of the universe.
d.
The Hubble constant is the square of the universe.
e.
It is impossible to tell the age of the universe from the Hubble constant.

Assume that the Hubble constant has been constant since the Big Bang. What is the possible range in the ages of the universe? Use the equation in the text, T0=1H , and make sure you use consistent units. (b) Twenty years ago, estimates for the Hubble constant ranged from 50 to 100 km/s per Mps. What are the possible ages for the universe from those values? Can you rule out some of these possibilities on the basis of other evidence?arrow_forward
