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
Which statement is true about the Big Bang Theory? Choose all that apply.
It should appear longer because of a redshift.
the universe formed by the rapid expansion of space from a point 10–20 billion years ago
The universe is expanding because light from faraway stars and galaxies is shifting towards the blue colors.
When stars and galaxies move farther away from each other, we say that the universe is expanding and that this is due to a shift in the frequency of light coming from these light sources.
What does the Big Bang Theory tell us
About the popular television show.
the entire universe was once condensed in the form of primeval atom, or a dense mass.

How does Cosmic Microwave Background Radiation support the Big Band Theory?
Microwaves are found everywhere in the universe.
Microwaves occurred at the time of the Big Bang
Microwaves are useful in our everyday lives
Only A & B
As galaxies move away from our galaxy
a shift on the electromagnetic spectrum
(EMS) is noticed. This phenomena is
called _____________.
redshift
blueshift
unshift
blackshift
How does the abundance of hydrogen and helium support the Big Bang Theory.
Hydrogen and helium are elements on the Periodic Table
Hydrogen and helium are in the same ratio throughout the universe.
Hydrogen and helium have many current uses today
Our theory of the universe was confirmed by the discovery of:
fusion.
cosmic microwave background radiation.
the Andromeda galaxy.
the Doppler effect.
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.
Lemaître imagined everything in the cosmos squeezed into one infinitely dense blob called ___
a “primeval atom” or the “cosmic egg”

It is the radiation emitted by black holes
It is the light from the nearest stars
It is the sound waves from the early universe
What does the Big Bang Theory suggest about the initial state of the universe?
The universe was once in an extremely hot and dense state
The universe has always been the same size
The universe was created by a collision of galaxies
The universe was formed by the cooling of a large star
