The Effect Of Nucleis In The Creation Of Star

incredibly radioactive. This is because” In general, uranium-235 and uranium-234 pose a greater radiological health risk than uranium-238 because they have much shorter half-lives, decay more quickly, and are thus "more radioactive” (EAD). .Their unstable nuclei emit electromagnetic energy that has a small enough wavelength to penetrate ones skin and a frequency high enough to alter DNA. This is a concern as events such as Chernobyl, Three Mile Island, and Fukushima have shown how far scale nuclear disasters

The Big Bang theory. The Big Bang, what is it? What does it tell us? How do we know that The Big Bag is a viable theory? The BIg Bang theory is currently the best theory (astro)physicists and cosmologists have to describe the beginning of the universe in which we live. The theory also has implications on how cosmologists think the universe will end. We call it the big bang as it was originally thought of as a preposterous theory; That the universe didn 't exist at some stage and then it just decided

A’rianna Duval Mrs. Kent English 8th 2 February 2015 The Sun The sun is actually a star just like the stars that shine throughout the night. The sun is a medium-sized star measuring 864,948mi (1,392,000km) across--100 times the diameter of the earth (Farndon 47). The core, the convection zone, and the photosphere are four main layers of the sun. The core makes energy from hydrogen for the world’s sight (Elvis 12). About 99 percent of the energy generated by the sun through nuclear fusion is produced

second, the universe is made up of fundamental particles and energy: from electrons, photons, to less familiar types. These particles merge together to form protons and neutrons which will combine to form the nuclei of simple elements such as hydrogen, helium and lithium. The first major creation of the universe was radiation – different wavelengths of light,

New energy sources are invested in every year to produce heat and electricity for the citizens of the United States. However, nuclear power is becoming a much more urgent discussion topic. Nuclear power, or the use of nuclear fission to generate heat and electricity, contributes to nearly 20% of the electricity generated and used in America. According to the Department of Energy, the United States has invested 60 years of their time into nuclear power! But why have we done so? Well, the production

Gravity and its theory, is relatively new. Scientists still discover new correlations that they attribute to Gravity. Greek philosophers attributed the “natural motion” of the planets and stars as a part of the gods’ realm. They did not realize that gravity was involved until astronomers like Galileo and Brahe in the 1500s, discovered that the Earth and other planets revolved around the sun. Kepler later showed that they moved in an elliptical orbit, not in a circular pattern, which brought speculation

There are many ways to observe the universe- Radio- telescopes can often sense radio waves coming in from space. Although, they are normally quite large and expensive, these telescopes in particular have an advantage over average telescopes. Telescopes used in space can observe the whole sky and they can operate 24hrs a day, regardless of weather. This is an advantage to astronomers because it means they can do their work any time they need, making it easier for them to do research for work etc

safety procedures Introduction Nuclear fusion is a form of nuclear reaction which occurs when two or more atomic nuclei collide at a very high speed and as a result, join to form a new type of atomic nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted into energy. Fusion is currently the process that powers active stars. Fusion was first achieved in 1951 with the Greenhouse Item nuclear test. Research

Even though the Big Bang and the Biblical Creation story seem to fit together, there are still lots of scientists who claim that people do not need to invoke a higher being to prove how the universe began. John Lennox discusses Hawking in his books and his view on religion which is that “the concept of God, or the gods, is a placeholder for human ignorance- a ‘God of the Gaps’, who will increasingly be displaced as the gaps in our knowledge are filled by scientific explanations” (Lennox 23).
