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

What does the Big Bang theory suggest?

• The universe was just there
• The Milky Way is the only solar system
• The universe is continually expanding
• The universe is collapsing in toward a single point

The "afterglow" of the energy from the origin of the universe that we see today.

• Cosmic microwave radiation

• sunlight

• Doppler effect

• Cosmic explosions

As galaxies move away from our galaxy

a shift on the electromagnetic spectrum is noticed. This phenomena is

called _____________.

• redshift

• blueshift

The distance light can travel in one year is ______________

• 15,000 kilometers

• 1 light-year

• 15 Astronomical Units

• 6,000 miles

What unit of measurement is used to calculate distance in our universe?

• astronomical units

• kilometers

• light years

• parsecs

A device that detects radio waves from objects in space is called a(n)

• radio telescope.
• reflecting telescope.
• refracting telescope.
• electromagnetic telescope.

Why do we use the entire electromagnetic spectrum to study space?

• Because the visible spectrum is such a small part of light we are missing out by not doing so.
• So we can determine the direction galaxies are moving
• So we can understand the nature of time.
• So we can see the composition of galaxies
