DO NOW

Put these in order from smallest to largest:
Supercluster
Galaxy
Planet
Star System
Cluster/Group

Then identify which structures WE are in. Ie. What supercluster are
we in? What galaxy are we in, etc. You may use your notes.
Our Universe BANGS!

Theory.

Spectroscopes
The light given off by stars is marked by
dark lines in certain colors
 A spectroscope is an instrument that
separates light into its component colors
 Since stars are primarily hydrogen and
helium, the lines
we usually see
are in the orange,
yellow, green
and blue areas

Edwin Hubble


In the early 20th century, Edwin Hubble
discovered that light that reached Earth from
distant galaxies shows special lines that are
shifted toward the red end of the spectrum
He suggested that the red-shifted lines are
evidence that distant galaxies are moving away
from us


Observations of distant
galaxies in all directions
showed the red shift
The more distant the
galaxy, the greater the
red shift
LEARNING OBJECTIVE:
I CAN explain the Big Bang Theory.
Expansion

The red-shift and other observations led scientists
to the conclusion that the universe is expanding

Big Bang Theory
Computer models that reverse the
expansion, lead to the idea that at one
time the universe was a concentrated
object of incredible mass and density that
exploded.
 This theory of the origin of the universe is
known as the “Big Bang Theory”
 Scientists currently believe the universe
is about 10 to 15 billion years old

Big Bang Theory

About 15 billion years ago, from
nothingness, very dense matter smaller
than a period exploded into what would
become stars, planets and galaxies.

I CAN explain the Big Bang Theory.
The Future of the Universe
Some scientists think that the expansion of
the universe will continue forever.
 Some astronomers believe the force of
gravity will eventually reverse the expansion
and the universe will fall back together in the
“big crunch.”
 Some astronomers think it is possible that
the universe will pulsate between explosions
and contractions.
