The Big Bang
For decades the Big Bang theory has been the leading theory on the beginning of our universe. Alternate theories come and go, but mainly go. As new data and research are continually eliminating alternatives to the standard model of cosmology, the Big Bang just keeps getting stronger.
Before discussing the alternate theories to the Big Bang theory, the basics of the early universe should first be understood. The main points opposing the theory are based around a few aspects that will be defined in the explanation of the early universe. These points include inflation, dark matter and dark energy, the cosmic microwave background (CMB), and red shift.
The theory states that the universe sprung from a singularity – an

Other wavelengths that can be observed daily by anybody are shifted in the same manner. "A good example of this is the sound of a fire truck siren as it drives by; the pitch of the siren is higher as the fire truck moves towards you, and lower as it moves away from you" (Shestople, 1997, para. 6). The redshift effect is commonly used in the Big Bang theory to explain that the universe is still expanding. Galaxies observed with higher redshift are then assumed to be the oldest, farthest away galaxies.
The Big Bang is, at the foundation, based on Einstein's Theory of General Relativity. Einstein's theory states rules of gravity and its behavior. However, observations of gravity and the mass of the universe do not seem to come together very well. Scientists now need to add another piece to the Big Bang, dark matter and dark energy. The gravitational observations show that the universe must be much more dense than could possibly be with normal matter. Dark matter is defined by Shestople as "Any matter in the universe which does not give off any light of its own, or does not interact with light the way typical matter does" (1997, Glossary, A-E, para. 16). Dark energy is described similarly as energy that does not interact in a way typical of normal energy. Dark energy is required to explain the continuing expansion of the universe after so many billions of years. New data from the CMB estimates the amounts of dark matter and dark energy in the universe (see
