Geography Question 1: The big bounce theory. The big bounce theory is a theory that scientists have created that shows that the universe was formed The big bounce theory is a scientific theory about the origins of the universe. Scientists say that our universe is the result of the previous universes collapse. The big bounce theory states that the universe expands and contracts. The universe expanded so greatly that it exploded and created the universe we’re living in today, The Milky Way.…

Analysis The Earth and the Universe: First of all, Hesiod’s Theogony (circa. 700 BC) is a written source explaining the connections between the gods, goddesses and these immortal beings are the embodiment respective parts of the earth and universe. Hesiod explains that in the beginning there was only Chaos and then came Gaea, the broad earth who supports Mt Olympus and at its core, Tartarus. From Gaea came Uranus, the sky and stars and together they bore the titans and titanesses and the…

The cosmos are a timeless collection of space and stars. It’s our home and it’s our Earth’s home. It holds the key to our survival, the sun. It it both where we came from and where we are going. The universe is all that we have, and human kind has developed the ability to explore it. But the real question is if we should. Some issues should be considered when it comes to space exploration, and those are economics, ethics, and science. These three things are the most important factors to consider…

radiation would also have been continuing to move away faster from us that the wavelength from this radiation would have been moved from being visible light to the CMB we see today. One of the major pieces of evidence for the big bang theory is that galaxies appear to be moving away from us at speeds that are relational to their distance. This piece of evidence is known as “Hubble’s Law”, and this phenomenon was discovered in in1929 by Edwin Hubble. His observation supports the expansion of the…

First, Energy has multiple forms that can switch different states. The two most common forms of energy are, Kinetic and Potential Energy. Kinetic Energy is the energy created when an object is in motion. It can be transferred between two objects if the object has enough energy, therefor it can be from of a collision. Kinetic energy can also be elastic or inelastic energy, however Potential Energy is an energy, but is potentially created before Kinetic Energy. Both types of energy are measured in…

figure out what it is, but no one truly knows what composes dark matter. Physicists are so interested in understanding dark matter because it accounts for the formation of the Universe, as observable through studying the distribution of gravity within galaxies (Carnegie). Original attempts at studying dark matter referred to dark matter as baryonic, which is a word used to describe baryons, or quark based particles. Quarks make up “normal” subatomic particles, and so when referring to dark…

Statement: Body: The Drake Equation’s general expression is N = R* fp ne fl fi fc L. N represents the number of communicating intelligent civilizations within the universe right now. R* is the approximate rate of the formation of stars within our galaxy. Fp represents the fraction of stars in the Milky Way that are companioned by other planets. Ne takes the place of the number of planets per sun-like star that have habitable ecospheres, which is what allows for the chemical evolution of…

Many scientists, starting with Galileo, had noticed there was something strange because of a small fleck they saw in the sky. These scientists had try to discover something new, but each time, their ideas were dismissed. This went on for several years, before William Herschel had the motivation to figure it out for himself. At first, he thought it was a comet, but through a mirror he had built, was able to verify that this object wasn’t making the same motion as a comet would. This is where his…

Theory on Lithium in Stars May Be Confirmed The light chemical element lithium is one of the few elements that is predicted to have been created by the Big Bang, 13.8 billion years ago. But understanding the amounts of lithium observed in stars around us today in the Universe has given astronomers headaches. Most heavy elements are produced during supernovae, as massive stars explode in their death throes. However, these events were believed to be too rare to produce the vast amount of…

Fixtures of the northern sky, the Big and Little Dippers, swing around the North Star, Polaris, once a day or once every 23 hours and 56 minutes. Polaris marks the north celestial pole around which all the stars of the northern sky appears to rotate. It also marks the end of the Little Dipper’s handle and the whole constellation (Ursa Minor) is circumpolar, which means it’s always above the horizon in northern latitudes to as far south as the tropic of Cancer (23.5 degrees north latitude). The…
