Hubble's Discoveries and the Big Bang Theory

What happens to the wavelength of light as an object moves away, according to redshift?

• It gets shorter, stronger, and faster.

• It gets longer, weaker, and slower.

• It remains the same.

• It gets shorter, weaker, and slower.

How did Hubble's findings impact the Big Bang theory?

• They showed galaxies are moving closer together.

• They showed galaxies are moving away from each other at a consistent rate.

• They showed galaxies are stationary.

• They showed galaxies are moving in random directions.

What does Hubble's constant measure?

• The speed of light.

• The rate the universe is expanding.

• The mass of galaxies.

• The temperature of stars.

What does Hubble's Law state about the speed of objects in the universe?

• The closer the object, the faster it's going.

• The further the object, the faster it's going.

• All objects move at the same speed.

• The speed of objects is random.

How do Hubble's findings support the Big Bang Theory?

• By showing the universe is shrinking.

• By showing the universe is static.

• By showing the universe is continuing to expand.

• By showing the universe is cooling down.
