Big Bang Theory Review #2

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

As galaxies move away from our galaxy

a shift on the electromagnetic spectrum

is noticed. This phenomena is

called _____________.

• redshift

• blueshift

• unshift

• blackshift

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 percent amount throughout the universe.

• Hydrogen and helium have many current uses today

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.

Which statement is true about the Big Bang Theory? Choose 2 choices.

• 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.

Which of the following is NOT evidence of the Big Bang Theory?

• most galaxies are red-shifted

• CMBR everywhere

• the universe is gaining matter

• the universe is expanding

Which piece of evidence supports the Big Bang theory?

• The more distant galaxies are moving the slowest
• The more distant galaxies are moving the quickest
• The more distant galaxies are moving towards us
• Galaxies and space is not changing

Is the Big Bang Theory completely true forever?

• Yes, it fits with current data.
• Yes, we believe it to be so.
• No, theories evolve with new data.
• No, it does not fit with data.

What were the original two elements in our universe?

• Lithium and Carbon
• Hydrogen and Neon
• Helium and Chlorine
• Hydrogen and Helium

Right after the big bang, what happened to all the matter and energy?

• It spread out in all directions
• It evaporated
• it shot forward in a straight beam
• It oozed slowly along a flat plane
