The Big Bang Theory

Why is the light from distant galaxies red-shifted?

• They produce more red light than nearby galaxies
• They are moving away from us
• The longer wavelengths are filtered out more by dust
• They are moving toward us

What is one major piece of evidence that the Big Bang theory is correct?

• Astronomers have detected leftover radiation from the Big Bang

• Everything in the universe has remained in the same location for billions of years

• Astronomers have discovered that the universe is no longer expanding

• Astronomers have discovered evidence that the universe will soon begin contracting in a "Big Crunch"

Which of the following is NOT true about the Big Bang Theory?

• It is the scientific explanation of how life began on Earth and evolved over time.

The three pieces of evidence for our current theory of the universe are:

• blueshift, cosmic background radiation, moon landing.

• redshift, doppler effect, Andromeda galaxy.

• redshift, comic background radiation, distribution of elements.

• doppler effect, light spectra, fusion.

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.

The universe is ____________ years old.

• 12 billion

• 14 billion

• 13 bilion

• 11 billion

Which description is considered most accurate regarding what actually happened during the Big Bang?

• Two galaxies collided causing an immense explosion as stars crashed into one another

• All of what would become the universe was concentrated in a single small point, or singularity, which rapidly expanded into what is now stars, planets, galaxies, matter, and energy.

• All matter emerged from a massive black hole at the center of the universe.

• Parts of the sun were ripped off by massive internal explosions and were thrown into space where they cooled to become other things, like plants, comets, and other galaxies.
