Dark energy what is it? Dark energy is a unknown energy said to take up 70 percent of the universe. The energy is a repulsive gravitational effect that is causing the universe to accelerate out-ward. No one knows exactly what dark energy is or where it comes from. Dark Energy is a new idea. Little is known about dark energy‚ yet it takes up a huge amount if the universe. Scientist were able to show the universe was expanding at an accelerated rate by measuring the red-shift of an object by comparing

The Nature of Dark Matter We observe the universe around us through many scientific means. However it is through the electromagnetic spectrum‚ that is everything from radio waves to gamma waves‚ that we learn about the objects in our world and beyond. However we can also learn about our universe through indirect means‚ such as the effect of gravity on light as well as larger objects like our galaxy. In fact it is this indirect method of observation that has led us to the discovery of extra-solar

Dark Energy VS Dark Matter Dark Matter Dark Matter is the name given to mass that emits no detectable radiation. ‘’Dark Matter accounts for the galaxies rotating about "local groups" in tighter orbits than we expect from our observations. Gravity is stronger than we can account for unless there is some matter we cannot see. We are much more certain what dark matter is not than we are of what it is” (Feild‚ Ann‚ 2013). Scientists think dark matter is made of particles called WIMPS‚ "weakly

Samurai and Knights: Were the Similarities Greater than the Differences? In Europe and Japan‚ very similar forms of government developed within a couple hundred years of each other. This occurred despite the fact that these two parts of the world were very distance from each other and it was very unlikely that these countries had contact with each other. This form of government‚ called feudalism developed in both places due to the need to establish order after a time in chaos. The knights and the samurai

of schooling‚ I have always been fascinated by medieval knights. Even as a child‚ I remember enjoying the tales of the great quests the knights would embark on. Whether it be slaying a mighty foe or adventuring to a far off land‚ the stories of knights were always exciting to hear. Because of this fascination‚ I chose to tell my creative tale in the style of Geoffrey Chaucer’s The Canterbury Tales from the perspective of the knight. Knights during the time of medieval England were responsible for

There is much more dark matter than normal (visible) matter in the universe. According to (this source) roughly 68% of the universe is dark energy. Dark matter makes up about 27%‚ while everything else in the universe (physical matter like the atoms that make up planets and stars) makes up less than 5% of the universe. According to (this source) the universe is actually 96% of dark matter and dark energy. With 73% being dark energy and 23% being dark matter but the implications of this

Dark Matter Astronomy Samuel Research Topic Topic: Dark Matter‚ Astronomy Saul Perl mutter‚ 2011 states “The Universe in made mostly of dark matter and dark energy‚ and we don’t know what either of them is.” The above statement by Saul Perl mutter suggests that astronomers at this age have found this unknown substance by the name of Dark Matter. We chose this topic on Dark Matter as it intrigues us what is beyond our atmosphere and what is it made off. We want to know how Scientists realized

Response: Intimations of Dark Tourism The study of dark tourism by Foley and Lennon displays a significant amount of research and examples. In pointing out the vast number of dark tourist sites‚ worldwide‚ the two authors validate the importance of dark tourism in anthropology. The manner in which a human views death depends completely on the way in which he or she was socialized from the time he or she was born.
