Question: what you mean with both red-and-blue shifted galaxies?
Here I want to answer all the Unanswered questions about Dynamic Universe Model in the previous thread.
Please refer to Wikipedia, http://en.wikipedia.org/wiki/Redshift, my definition is same.
In physics and astronomy, redshift occurs when electromagnetic radiationusually visible lightemitted or reflected by an object is shifted towards the (less energetic) red end of the electromagnetic spectrum due to the Doppler effect. More generally, redshift is defined as an increase in the wavelength of electromagnetic radiation received by a detector compared with the wavelength emitted by the source. This increase in wavelength corresponds to a drop in the frequency of the electromagnetic radiation. Conversely, a decrease in wavelength is called blue shift.
I am requesting you all to please feel free to ask any further questions...
