Expanding Unverse

       It is currently accepted the measured Red Shift of our universe is due to the expansion of our universe as a result of the Big Bang, yet the rate of expansion is the same in all directions with the rate of expansion increasing with distance. Neither of these observed characteristics would be consistent the known effects of a single point event such as the Big Bang.

      Redshift can be caused by the Doppler effect, but it can also be the result of frequency decay of a light source over time. Redshift is currently considered as the result of the Doppler effect due to an expanding universe with the amount of redshift directly proportional to the rate of expansion. 

      While the redshift certainly could be the result of expansion it could very likely also be the result of the wavelength decay of the light source over millions, or even billions, of years traveling through space.  The redshift can be used to measure the rate of expansion if the distance is known. It seems highly unlikely two variables can be accurately measured with only one data value. 

      The observed redshift is likely the result of frequency decay over time and distance. Following this line of thinking we might conclude the rate of expansion is not only the result of the Doppler effect caused by an expanding universe, but also simply frequency decay.
