How does Cosmic Microwave Background Radiation support the Big Bang theory? It is

energy left behind from the Big Bang as radiation

LIght wave stretch as an object moves away from you.

According to scientific theory, what has happened to matter in the universe since the Big Bang?

Matter has moved outward and collected into galaxies

An explanation based on LOADS of evidence and has been well tested

Choose all of the evidence for the Big Bang Theory?

Lots of H2 and He, Expansion of the Universe, Cosmic Microwave Background Radiation

What was the dark era that happened after the Big Bang?

There was no light because stars hadn't formed yet.

How does redshift help prove the Big Bang

It shows the universe is expanding outward from the Big Bang

How would an astronomer explain the difference between the two spectra?

The star is traveling away from us, stretching light waves

Answers

1
How does Cosmic Microwave Background Radiation support the Big Bang theory? It is
the theory that has never been explained
light that has traveled to the edge of the universe
energy left behind from the Big Bang as radiation
radiation that got moved out of the way during the Big Bang
2
What is redshift?
LIght wave stretch as an object moves away from you.
LIght waves stretch as an object moves closer to you.
Light waves compress as an object moves away from you.
Light waves compress as an object moves closer to you.
3
According to scientific theory, what has happened to matter in the universe since the Big Bang?
Matter has been stable and unmoving ever since
Matter has moved outward and collected into galaxies
Matter has moved from one end of the universe to another
Matter is contracting and coming back together again
4
Why do scientists accept the Big Bang theory?
evidence supports it
it is a belief based on faith
they trust other scientists
it seems to make sense
5
What is a theory?
A hypothesis you have from info you got on Tik Tok & Google
An explanation based on LOADS of evidence and has been well tested
A guess based on a little bit of evidence
Your hopes and dreams
6
Choose all of the evidence for the Big Bang Theory?
Really old stars
Lots of H2 and He
Expansion of the Universe
Cosmic Microwave Background Radiation
7
What was the dark era that happened after the Big Bang?
Ironically, there was lots of light and lots of stars
Stars had formed but weren't shiny, yet.
It was also called the Medieval Times
There was no light because stars hadn't formed yet.
8
How does redshift help prove the Big Bang
It was the only elements formed from the Big Bang
It shows all the left over energy from the Big Bang
It shows the universe is expanding outward from the Big Bang
It shows the universe is contracting from the Big Contraction
9
This is a model of Cosmic Microwave Background Radiation.
True
False
10
How would the spectrum of hydrogen on the distant star be described?
Offset
Reflected
Red-shifted
Refracted
11
Which elements were formed shortly after the big bang?
Water & CO2
Carbon & Oxygen
H & He
Nitrogen & Lithium
12
How would an astronomer explain the difference between the two spectra?
The star is fusing a different kind of hydrogen than the sun
Hydrogen gives off light differently if star is more distant
Light traveling through space is warped by the vacuum
The star is traveling away from us, stretching light waves
