    'Sheenagh Pugh presents us with a Sad View of the Future and a Grim Warning of What Could Be. Discuss How She Does This, Paying Particular Attention to the way She Uses Mood and Language and how She Organizes the Poem.'

    4 star(s)

    The poem is set out as 24 short-worded lines and is also written in a free-flowing verse just like 'Do you think we'll ever get to see earth sir?'. The poem creates a sad atmosphere, by using phrases such as 'not back to port'. This shows that they, the survivors, are trying not to feel sad and are not looking back. They are looking forward to the place that they are going and the future that they will have. In line 2, one of the survivors says 'at least that was the name scratched on the smooth door', which creates sound in the poem - sibilance - the use of the 's' on 'scratched' and 'smooth'.

    Concepts of the universe creation

    4 star(s)

    In 1965, Radioastronomers Arno Penzias and Robert Wilson discovered a 2.725 degree Kelvin (-454.765 degree Fahrenheit, -270.425 degree Celsius) Cosmic Microwave Background radiation (CMB) which pervades the observable universe. This is thought to be the remnant which scientists were looking for. Penzias and Wilson shared in the 1978 Nobel Prize for Physics for their discovery. * Finally, the abundance of the "light elements" Hydrogen and Helium found in the observable universe are thought to support the Big Bang model of origins.

    The Life Cycle of the Stars

    4 star(s)

    In the Hierarchy of the universe, stars play an important role. They are huge bodies that have come into being from great clouds of light elements, either with the stars forming simultaneously, or in later evolution of the galaxies. When a star is born out of enormous clouds of gas and dust, they come together into a gigantic ball. Then there is the pressure from all the gas and dust banging into each other and it can reach millions of degrees in temperature.

    What types of problems and effects are been forced upon the planet with modern technology and the increasing population and what can be done to make the planet healthier?

    4 star(s)

    Paper which is made from trees should not be wasted and recycled when finished with. In order to prevent unnecessary usage of the planets resources' recycling helps to curb the effects of deforestation. Whenever a person uses a car or forgets to switch their television off at the mains, leaving the little red light to waste energy, a thought should be spared for the millions of men women and children that survive every day in third world countries who have quite possibly never seen a television. If every commuter car in the U.S. transported an extra person, it would save eight billion gallons of fuel a year.

    Physics Research and Report - What is Antimatter?

    3 star(s)

    In other words it will be total destruction or complete obliteration. It produces pure energy, which can be dangerous if not contained properly, though if it is it can be useful in more ways than one. After annihilation, charge, momentum and energy are all conserved. Why is there more Matter than Antimatter? There is a substantial amount more Matter in the universe than there is Antimatter. One of the reasons why this could be is: In the first few moments of the universe, the Antimatter might have decayed differently than their regular Matter counterparts.

    Analysis of our Solar System

    3 star(s)

    These nine major planets in order from the centre are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Mercury is the planet nearest to the Sun. As it orbits the Sun, it does not rotate, keeping the same face of the planet toward the Sun at all times. This means that one side of the planet has a continual burning day of 900�F, and the other side a continual night and a deadly cold of 450�F below zero. Mercury is the fastest travelling of the nine planets making one full orbit around the Sun in only eight days.

    Black Hole

    3 star(s)

    At that point, light particles would not be able to leave the surface of the star, and it would blink out and become an invisible black star. More than a century later, Albert Einstein, in his special theory of relativity, maintained that nothing can move faster than light. This means that Laplace's black stars are also black holes, because if light cannot escape, all other matter must be trapped as well. The surface of the black hole thus acts like a one-way membrane: material may fall into a black hole, but no information or energy can come out of a black hole.
