Myths And Legends Oxygen Atoms
878 wordsIn certain polar regions of the earth, a rare and fascinating phenomenon occurs in the dark season of winter. This phenomenon is called the Northern Lights, or auroras. In areas where auroras can be seen, the sun shines brightly for six months and then disappears for the next six. The sun follows a straight path across the sky, rising in the north and setting in the south. This is because of the latitude of these regions. Unlike other regions of earth, the polar regions either completely face th...

Hubble Space Telescope Universe Continues To Expand Energy
786 wordsThe universe begins with a cataclysm that generates space and time, as well as all the matter and energy the universe will ever hold. For an incomprehensibly small fraction of a second, the universe is an infinitely dense, hot fireball. The prevailing theory describes a peculiar form of energy that can suddenly push out the fabric of space. On a rare occasion, a runaway process called "Inflation" can cause a vast expansion of space filled with this energy. The inflationary expansion is stopped o...

Gas And Dust Billions Of Years
1,652 wordsOur lives are intimately linked to the stars, but in ways much more down to earth than the romantic views of them. As we all know, our sun is a star and the thermonuclear reactions that are continuously taking place inside it are what provide and sustain life on our planet. What do we get from the sun? We get carbon, oxygen, calcium and iron, courtesy of stars that disappeared billions of years ago (Naeye, 1998). Star formation is a study in contradictions because the formation of a star begins ...

Infinite Regress God Exists
1,002 wordsAquinas second proof that God exists, the proof from efficient cause, is summarized in the following: there exists things that are caused, nothing can be the cause of itself, there cannot be an infinite regress of causes, there fore, God exists. The proof of Aquinas s is a cosmological kind, basing the fact the if anything exist; an absolute necessary being must also exist. I agree with Aquinas that God is the uncaused first cause, but from a situation that was discussed in class a few weeks ago...
