Big bang Theory

What does the Big Bang Theory tell us

• About the popular television show.

• the entire universe was once condensed in the form of primeval atom, or a dense mass.

• how the universe began.

Most scientists believe the Big Bang Theory explains which of the following questions?

• How our planets and moons formed

• How our universe began

• How the sun turns hydrogen into helium

• How fast light travels through space

Which statement is true?

• The galaxies are moving toward us.

• The galaxies are moving away from us.

• The universe remains static or unchanged in motion.

• None of the above

Light emitted from a star or galaxy can be separated into a band of colors, called a ________.

• Red Shift

• Wave Length

• Spectrum

• Microwave

How does the abundance of hydrogen and helium support the Big Bang Theory.

• Hydrogen and helium are elements on the Periodic Table

• Hydrogen and helium are in the same ratio throughout the universe.

• Hydrogen and helium have many current uses today

Our theory of the universe was confirmed by the discovery of:

• fusion.
• cosmic microwave background radiation.
• the Andromeda galaxy.
• the Doppler effect.

The universe is expanding!  This means that:

• all of the galaxies are spreading out.
• the universe must have started from a single point.
• the universe is cooling down.
• all of the above.

Spectroscopes can tell us all of these about except...

• Temperature of a star
• Elements that make up a star
• Age of a star
• Size of a star

Which statement is true about the Big Bang Theory? Choose all that apply.

• It should appear longer because of a redshift.

• the universe formed by the rapid expansion of space from a point 10–20 billion years ago

• The universe is expanding because light from faraway stars and galaxies is shifting towards the blue colors.

  
  

• When stars and galaxies move farther away from each other, we say that the universe is expanding and that this is due to a shift in the frequency of light coming from these light sources.

• Big Bang Nucleosynthesis

• Nuclear Fusion

• Nuclear Fission
