Explore the origins of the universe through the Big Bang Theory and the Red Shift evidence supporting it. Learn how scientists believe our universe was created and evolving through concepts like Open and Closed Universe models. Dive into the fundamental question of the universe's creation and the scientific evidence that backs it up.

Topic: Origins of the UniverseEssential Question: How do scientists think our universe was created and what evidence supports it? The Universe • Defined as everything that physically exists • All of space and time • All forms of matter and energy
Topic: Origins of the UniverseEssential Question: How do scientists think our universe was created and what evidence supports it? Big Bang Theory • All galaxies started from one huge mass of densely packed matter • The densely packed matter exploded with a “big bang” sending out matter and energy in all directions • Over time the matter grouped together to form the stars and galaxies that now exist
Topic: Origins of the UniverseEssential Question: How do scientists think our universe was created and what evidence supports it? The Red Shift • Evidence that the universe is expanding (supports Big Bang Theory) • Distant galaxies give off a red light • The red end of the spectrum has the longest wavelengths
Topic: Origins of the UniverseEssential Question: How do scientists think our universe was created and what evidence supports it? The Red Shift • If a galaxy is moving far away, the wavelengths become longer (or stretched out) • All galaxies beyond our own show a red shift, so it is believed that the universe is expanding
Topic: Origins of the UniverseEssential Question: How do scientists think our universe was created and what evidence supports it? The Blue Shift • Galaxies that are moving closer give off a blue shift • If a galaxy is moving closer, the wavelengths become shorter giving off a blue shift
Topic: Origins of the UniverseEssential Question: How do scientists think our universe was created and what evidence supports it? Open Universe a model of the universe in which the universe expands forever Closed Universe A model of the universe in which the universe, because of gravity, everything ejected during the Big Bang will eventually be pulled back to a central point.
Now take some time… • Take 2 minutes to go over your notes and highlight or underline the main ideas that answer the essential question, you should not highlight everything: • Essential Question:How do scientists think our universe was created and what evidence supports it?
Time to use the left hand column • You will now write your own questions using the verbs provided.
