Slide 2: Background Information  Scientists believe that the Universe is ever expanding because of the increase in galaxies and heavenly bodies.  This heavily implied that the growth of these heavenly bodies was rapid.  These were the basis of the scientists’ argument that the universe was expanding. 12/14/10
Slide 3: Big Bang Theory  The term Big Bang generally refers to the idea that the Universe has expanded from a prehistorically hot and dense initial condition at some finite time in the past.  Georges Lemaitre proposed what became known as the Big Bang theory of the origin of the Universe. The framework for the model relies on Albert Einstein’s general relativity and on simplifying assumptions. 12/14/10
Slide 4: Big Bang reasoning  Fred Hoyle is credited with coining the term Big Bang during a 1949 radio broadcast.  Scientists knew by both experiments and observations that our heavenly bodies were moving slowly apart.  Earlier and as time passed our planets, starts, galaxies. Solar systems were packed closely together in a burning environment. 12/14/10
Slide 5: Added Proof  Scientists with many advanced tools, have calculated the wavelengths from the stars.  As time has wore on, the wavelengths have increased which is called red shift.  Now we know that the wavelengths have increased over time, we know that the stars have accelerated away.  This proves that there was a point that everything was condensed some point in time about (13 million years ago.) 12/14/10
Slide 6: Pictures This picture shows how earlier all of the planets were condensed and as time wore on the gradually fell apart. Some people say that even the space itself is 12/14/10
