The universe

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

Galaxies that are REDSHIFTED are:

• actually BLUE

• really NEAR earth

• invisible or not visible

• moving AWAY from us.

If something that makes light is moving AWAY from you, it spreads the wavelengths of light out. This application of the Doppler effect is known as ___.

• blue shift

• green shift

• red shift

• black shift

A DATE that is commonly accepted by Big Bang theorists for the Big Bang is ____ years ago.

• 100,000

• 250 million

• 13.8 billion

• 10 trillion

The CMB (Cosmic Background Radiation) is:

• the remaining energy from the big bang.

• incredibly cool.

• a cloud of light

• only located in certain places in the universe.

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.

Light emitted from a star or galaxy can be separated into a band of colors, called a ________.

• Red Shift

• Wave Length

• Spectrum

• Microwave

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.

Which elements are most

abundant in the visible

universe?

• Hydrogen and Carbon

• Carbon and Helium

• Hydrogen and Oxygen

• Hydrogen and Helium

The universe is expanding.  This means that:

• Galaxies are getting bigger.
• Atoms are getting bigger.
• The universe is creating more matter.
• The amount of space between galaxies is increasing.
