Summary
The paper "The Velocity of a Galaxy" states that Marine mollusks have a number of series of million years in the universe. The world is old enough to have been completed for many years. The decay of the radioactivity processes also passes a number of age measures of the rocks and minerals on earth…

Extract of sample "The Velocity of a Galaxy"

Vr = CZ
C which is considered to be the speed of light is 300,000 Km/s and Z is the redshift respectively.
To find the Redshift, the fraction of the two wavelength ratios must be considered.
This is shown in the below calculations.
Z = (Wavelength- Rest Wavelength)/ Rest Wavelength)
Therefore the Velocity is,
300,000 X (Wavelength- Rest Wavelength)/Rest Wavelength)
a) Galaxy I has a Wavelength of 8204 and the Rest Wavelength of 6563. Therefore, the calculation of the Radial velocity will be;
300,000 Km/s (8204-6563)/6563
= 75011.4277 Km/s
b) Galaxy II has a wavelength of 6549 and the Rest Wavelength of 6563. Therefore, the calculation of radial velocity will be as follows;
300,000 Km/s (6549-6563)/6563
= -639.95124 Km/s


2. Concerning particle interaction, the following reactions must take place;
Conservation of energy takes place in the process of the interactions thus involving the momentum aspect. Besides, the conservation of charge takes place together with the Lepton and the Baryon number. A strong interaction between the weak particles occurs hence making the process of annihilation take place that involves a proton and an antiproton. For one anti-up and up quark to take place, annihilating which is responsible for producing energy is examined.
3. Proofs about dark energy which are related to the galaxy clusters have been developed and they have distance difference that shows the densities of the galaxy which has a year difference from the universe. The proofs were presented through the view of the South Pole Telescope where the brightest cluster of galaxies has been found. They are undergoing a violent internal motion caused by a smashup from other galaxies. Abell 3627 generates an x-ray that is blue along with hydrogen light. On the other side, Eso 137-001 galaxy has been seen for 260000 light years. It has a tail that scientists have failed to understand to date. Clusters of galaxies are a collection of galaxies that are bonded by gravity that is bounded by hot gases. The tails were formed from the hot gas formed by the spiral arms of the galaxies. This causes an effect on the galaxy hence evolution changes the formation of the stars.
4. In relevance to the top-down structure formation, the scenario first forms the large pancakes then followed by the fragment that forms the lumps which are sized. The scenario is important because of the information concerning the existence of large sheets with low density. In respect to the bottom-up structure scenario, there occurs a formation of the galaxies which are small and dwarfs first, followed by the formation of the clusters. Read More
