What we see as color is really just different ​ (a)   of light. Shorter wavelengths appear ​ (b)   while ​ (c)   wavelengths are red. When a galaxy is moving ​ (d)   from Earth, its motion "stretches" the wavelength of light that we see causing it to appear ​red . As the galaxy accelerates, the color turns more red in a phenomenon known as red ​ (e)   .

• wavelengths
• blue
• longer
• away
• shift

When you look into deep space and see galaxies that are far away, you are actually seeing ________________________________ .

• light that bounced off the galaxy a long time ago

• light that bounced to your eyes and back to the galaxy

• light that was created by the galaxy about a year ago

• light that was created when that galaxy was formed

What evidence do scientists have to support the Big Bang Theory? (select ALL that apply, meaning there is more than one answer)

• background radiation

• the Hubble Telescope was able to take picture of the exact time this event happened

• composition of the universe is mostly hydrogen and helium

• because Albert Einstein said so... and that's the bottom line!

• galaxies are moving further apart from each other
