14 billion years ago
20 billion years ago
5 billion years ago
What elements were first formed as the universe cooled and protons and neutrons came together?
Carbon and oxygen
Hydrogen and helium
Iron and silicon
Nitrogen and phosphorus
What does the red-shift observed in most galaxies suggest about their movement relative to Earth?
They are moving towards Earth
They are stationary relative to Earth
They are moving away from Earth
Their movement is random
What is the Cosmic Microwave Background Radiation (CMBR)?
Radiation from the Sun
Leftover heat radiation from the Big Bang
A type of pollution in space
Light emitted by stars
How was the Cosmic Microwave Background Radiation first discovered?
As a disturbance in television signals
As noise during radio signal research
During a space mission
By a telescope designed for this purpose
According to the Big Bang Theory, what was the initial condition of the Universe?
Cold and dense
Hot and dense
Hot and sparse
Cold and sparse
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.
What is the significance of the redshift observed in distant galaxies?
It indicates that the universe is contracting
It shows that the universe is static and unchanging
It suggests that the universe is expanding
It proves that galaxies are moving towards us

How does the Cosmic Microwave Background Radiation support the Big Bang Theory?
It shows that the universe is infinite
It provides evidence of the universe at a very hot and dense state
