origin of universe and life cycle of stars

Evidence suggests that the whole Universe is expanding and that it might have started billions of years ago from one place with the big bang.

• True
• False

Hubble observed that galaxies are

• expanding
• moving away from us
• moving towards us
• standing still

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

What do the initial moments after the Big Bang have in common with the universe as it exists now? 

• all the stars, galaxies, and planets that exist today were formed just a few moments after the Big Bang
• The universe back then could not sustain life, and it cannot sustain life now
• the universe was extremely hot then, and it is still extremely hot not
• the universe began expanding then, and it is still expanding today

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

About how long ago do scientists believe the universe began?

• 13-14 billion years ago
• 13-14 million years ago
• 12-13 billion years ago
• 12-13 million years ago

In red shift, the wavelengths of light become

• Bluer
• shorter
• longer

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