The Universe
Millican Earth Science B-DAY
Notes
Slides 1-8
2

• The Universe is a vast expanse of space which
  contains all of the matter and energy in
  existence.
• The Universe contains all of the galaxies, stars,
  and planets.
• The exact size of the Universe is unknown.

3

• Scientists believe the Universe is still
  expanding outward. They believe this outward
  expansion is the result of a violent, powerful
  explosion that occurred about 13.7 billion years
  ago.
• The Big Bang.
• By looking at an object's electromagnetic
  spectrum, scientists can determine if an object
  is moving away from Earth or towards Earth.
• If the shift is toward red, the light given off
  by the object is in longer wavelengths. When an
  object moves away from Earth, the light that it
  is giving off is seen in longer wavelengths.
• Red Shift

4

• When an object moves toward Earth, the light that
  it is giving off is seen in shorter wavelengths.
  This causes a shift in the object's spectrum
  towards violet.
• Blue Shift
• Whenever there is a shift in a spectrum, it is
  called a Doppler Shift. The amount of shift in an
  object's spectrum is determined by how fast the
  object is moving. All of the distant galaxies
  have tremendous red shifts. Based on these data,
  scientists believe the Universe is still
  expanding outward.

• Comparison with the Cancer symbol, the Crab
• A crab is able to walk or run sideways.
  Similarly, Cancer natives can sometimes "move
  about" in life, in a figurative sense, in an
  indirect manner. The crab's body is covered by a
  carapace (shell). Cancer natives are
  self-protective and sensitive, and often retreat
  into themselves when hurt. Crabs are able to
  resist changes in the environment, thereby
  protecting themselves from hostile elements in
  various habitats. Similarly, Cancer natives are
  thought to avoid too much change, and to be on
  the defensive. Crabs have "complex  behavior
  patterns" (1). The inner world of Cancer natives
  is thought to be rather quirky and complex. Some
  crabs "conceal themselves by decorating their
  bodies with plants and animals" (2). Cancer
  natives tend to try to blend in with their
  environments, preferring not to make a big splash
  in life.
• Cancer's glyph, or symbol, may represent the
  breasts as a symbol of the nurturing qualities of
  the sign.

29
Planet Ruler

• The Moon, in Astrology, is the ruler of Cancer.
  The Moon represents our deepest personal needs,
  our basic habits and reactions, and our
  unconscious. 
• Where the Sun acts, the Moon reacts. How do we
  instinctively react or respond to problems? What
  do we feel we need for a sense of security? Look
  to the Moon in your natal chart for answers.
• The Moon ( ) is associated with the mother and
  with feminine energy in general. The Moon is both
  our inner child and our inner mother. It is
  responsive, receptive, and reflective. The Moon
  is our spontaneous and instinctual reactions.
• Just as the Moon circles the Sun, in a
  symbolically protective manner, and reflects the
  Sun's light, the Moon in our chart shows how we
  protect ourselves, as well as make ourselves feel
  secure, comfortable, and safe.
