EXPANDING UNIVERSE

Compare and Contrast the formation of the Universe and Solar System
The two most common beliefs of the formation of the Universe and Solar System are The
Expanding Universe Theory and The Big Bang. There are some comparisons between the two
and some contrasts. Almost all astronomers believe that the universe is expanding
although they may have different theories on how this is happening.
The Expanding Universe Theory is based on the Doppler Effect, the redshift of different
galaxies and the assumption of the Hubble Law. The Doppler effect occurs when a
wave-emmitting object moves toward or away from an observer and the sound has a change in
pitch as the object continues to move. For example the sound a police car siren when it
comes from behind and passes you. The redshift of different galaxies is the change or
shift in the light radiated by an object such as a star of galaxy that indicates the
objects motion. Scientists have used redshifts to measure the speed and direction of
distant galaxies. The Hubble law showed that the further away the galaxies were the
higher the redshift was, that means the more distant galaxies were moving away at a much
faster velocity than those closer to us. The Expanding Universe theory is merely an
assumption by astronomers that all the galaxies in the universe are moving away from the
earth. The more distant the galaxy the faster it's moving away from us.
According to the Big Bang theory a gigantic explosion created the universe billions of
years ago. It appeared that the universe we now see could be the remnants of an enormous
explosion of the distant past. Many discrepancies between observations and the theory
have appeared, each requiring alteratio
