In the conservation of Byron number, each of the byrons is assigned a Byron number B=1 which is considered to be equivalent to assigning quark a baryon number of 1/3. It implies that the mesons with one quark and one antiquark have a Byron number B=0 and there is no unknown…

Extract of sample "3"

1 Galaxy observed to have hydrogen line wavelength of 8204 angstroms. Galaxy2 observed to have hydrogen line wavelength of 6549 angstroms. The rest hydrogen line measurement from the lab is 6563 angstroms wavelength.
Therefore the radial velocity of the galaxies is; Vr=cz {speed of light * redshift}
Radial velocity of galaxy 1,
redshift z = (8204 – 6563) / 6563 = 0.25
:. Vr = 300000km/s * 0.25 = 75000 Km/s
Radial velocity of galaxy 2,
Redshift z = (6549 - 6563) / 6563 = -0.002
Vr = 300000km/s * - 0.002 = -639.95km/s
A negative radial velocity implies that the distance between galaxy 2 source and the observer was gradually decreasing.
2.) The conservation rules
In the conservation of Byron number, each of the byrons is assigned a Byron number B=1 which is considered to be equivalent to assigning quark a baryon number of 1/3. It implies that the mesons with one quark and one antiquark have a Byron number B=0 and there is no unknown decay process interaction in nature changes the net baryon number.
3.) The existence of the dark energy is evidenced by the observations of distant supernovae
that indicates the expansion of the universe has been speeding up for the last several billion years and seems quite strong. The expansion of the universe is governed by two competing processes which tend to drive galaxies apart from one another and a gravitational attraction of matter in the universe that assembles galaxies together. Astronomers can notice the changes of the rate of expansion of the universe through measurements of the recession speeds and distances of very distant galaxies (Materrese & Sabino 2010).
The assumption of the dark energy is that it is a gravitationally repulsive force which does not appear to cluster in galaxies. It has last been seen to stretch the space–time apart and certainly fits the accelerating-expansion scenario. Therefore acceleration of the expansion implies clearly the existence of some force that acts to push galaxies apart, and the source of this force is the dark energy.
4.) Scenarios for structure formations: Top-down scenario
In this scenario large structure size galaxy clusters are formed first then they are segmented into galaxies. This scenario is based on radiation smoothed out the matter density fluctuations to produce large pancakes which then gradually build-up matter after recombination and grow until they collapse and fragment into galaxies.
Bottom-up scenario
In this type, small dwarf Galaxies form first then they merge into clusters of galaxies. The density enhancements at the time of recombination are close to the size of small galaxies and the enhancements collapses from self-gravity to form dwarf galaxies.
5.) The “Modified Newtonian Dynamics” MOND
This is a theory that was proposed by mordehai milgrom and it attempts to explain the galaxy rotation problem by modifying the Newton’s second law of motion, so as the acceleration at very low values such as between distant stars is not strictly linear. It tries to resolve the problem that when astronomers observe galaxies and apply the current theory of gravity, the result shows the stars within the galaxy should go spinning apart from each other. Most astrophysicists and cosmologists do not believe that MOND fits the evidence. This falls in the somewhat less-informal category of an alternative gravity theory since it proposes fundamental changes to the understanding of the way gravitational force works, as opposed to dark matter theory, which proposes that the understanding of gravity is fine (Mckenney & Jana 2012).

Averys work is the springboard for everything from recombinant DNA work to human cloning to cancer research. It has been used as a basis for other experiments that do not merely change the host genetic makeup, but actually replace one gene with another gene, and this process has even further widened the implication of Averys work. Drug resistant bacterial infections have been stemmed in part because of the processes used by Avery, in which injurious agents are introduced into the drug resistant strains, and these injurious changes are passed down through the progeny. The implications of this work for every aspect of life, from the environment to medicine to crop engineering is explored within the confines of this paper.

...HISTORY OF COMPUTING TIMELINES INTRODUCTION Before the invention of computers centuries ago the mode of relaying information was by the caravans who were common in India and the Middle East. These groups of people were mostly mathematicians who traveled long distances and passed the information to the people. This continued for quite some time as the technological evolution took place until the realization of a computer. The invention of the computer was not for email or entertainment purposes but was particularly to aid in solving serious issues of crunching numbers. For instance by the year 1880 the population of the United States was so large that it could take almost seven years that to tabulate the results of the census... OF COMPUTING...
