Antimatter

Nuclear powered unmanned space vehicles (USVs) represent the future of deep space exploration. Deep space missions require a power source that can travel further, go faster, and last longer than traditional chemical rockets or solar powered propulsion systems; nuclear powered platforms provide an ideal alternative. The United States is currently working cooperatively with other countries to research and develop nuclear power sources for space travel. Examples of unmanned deep space missions include

the speed of light. With this speed, he calculated the estimated time of arrival to be around 2126. The space craft is powered by the effective fusion reactor generator, in which a controlled fusion reaction is performed releasing small amounts of antimatter. The massive

Joel E. Cohen once stated in his How Many People Can the Earth Support?, “A little boy wanted to know the sum of one plus one. First he asked a physicist, who said, “If one is matter, and the other is antimatter, then the answer is zero. But if one is a critical mass of uranium and the other is a critical mass of uranium, then that's an explosive question.” Unenlightened, the little boy asked a biologist. She said, “Are we talking bacteria, mice or whales? And for how long?” In desperation, the boy

Dark Matter was first proposed by Fritz Zwicky in the 1930’s when he observed the motions of galaxies and he noticed that the amount of visible objects could not account for the observations he made. There had to be some “invisible” mass holding these galaxies together. It is known that 25% of our universe is made up dark matter versus 4% of the visible matter we know and interact with every day. The leading candidates for dark matter are MACHOs and WIMPS. Gravitational lensing is one of the ways

Chapter 1: Introduction 1.1 PURPOSE OF PROJECT To quantify the long term health risk for the general population exposed to radiation by the Fukushima-Daiichi Nuclear disaster in the aftermath of the 2011 Great Eastern Japan Earthquake and Tsunami. 1.2 BACKGROUND On the 11th March 2011, following a magnitude 9 earthquake in the Pacific, a fifteen meter tsunami hit Honshu, the main island of Japan, killing over 19,000 people and damaging the Fukushima-Daiichi Nuclear Power Plant. Over the following

Why We Should Be Heading Towards Space Space exploration is something that has intrigued mankind ever since science fiction writers of old sparked the imagination of the people. Since then, we have made leaps and bounds towards space travel with landing people on the moon, sending satellites to Saturn, the photos from the Hubble Telescope and the rover, Curiosity, on Mars. These advances have provided information that will prove to be beyond measure. While the cost of such information has been high

1. As seen from temperate or tropical latitudes, the positions of the constellations shift gradually westward in the sky from night to night because (a) the Earth rotates on its axis. (b) the Earth revolves around the Sun. (c) the tilt of the Earth’s axis changes. (d) their right ascensions constantly change. (e) their declinations constantly change. 2. A star cluster in which the individual stars do not show a striking central concentration nor an orderly pattern or structure is

It is the year 2034, a large asteroid is approaching Earth; it will impact in 30 years and is so large no amount of manpower can stop its course. Humans are forced to abandon Earth and move to Mars. To do so they will have to engage robotic missions to probe habitable areas, solve the problems of long-term space travel, figure out mass transport of humans, and deal with radiation exposure from the sun and other space hazards. It may seem like an impossible feat but the ingenuity of humans will have

2000 years ago the Greek philosopher Democritus came up with the idea that if he cut an object in half, for example a rock, that he could eventually cut it until he reached a tiny piece that could no longer be cut or divided. Democritus named this unbreakable piece ‘atomos’ which in greek meant ‘indivisible/ uncuttable’. However this idea was rejected in favour of another philosopher, Aristotle, whose theory was that all matter was made up of 4 elements, fire, water, air and earth. For thousands
