the Big Bang Theory

Front

What does the blue shift of light indicate about a star's movement?

Back

The star is moving toward Earth.

Front

What is the term for the shift in light patterns moving toward the right side of the spectrum?

Back

Blueshift.

Front

Is the universe still expanding?

Back

Yes.

Front

What happens to a low mass star when it begins to run out of hydrogen fuel?

Back

It becomes a red giant.

Front

Which star is likely to have the most redshift?

Back

Star D.

Front

What is the significance of redshift in astronomy?

Back

Redshift indicates that an object is moving away from the observer, often used to measure the expansion of the universe.

Front

What is the relationship between the Doppler effect and the blue shift?

Back

The Doppler effect explains how the frequency of light changes due to the motion of the source; a blue shift occurs when the source moves toward the observer.

Front

What is a red giant?

Back

A red giant is a late stage in the life cycle of a low to intermediate mass star, characterized by expansion and cooling.

Front

How does the expansion of the universe affect distant galaxies?

Back

Distant galaxies are moving away from us, leading to redshift in their light due to the expansion of space.

Front

What evidence supports the Big Bang Theory?

Back

Evidence includes cosmic microwave background radiation, the abundance of light elements, and the observed redshift of distant galaxies.
