Spherical Earth

1190, concerns Aristotle’s natural philosophy and the astronomers’ conflicting truths. Around the twelfth century, most were a devoted Aristotelian, and educated people knew that stars in the celestial realm only had one motion, to revolve in a spherical motion around the centre of the universe . What Maimonides notes however, is that Aristotelian physics could not infer the existence of epicycles and eccentric circles. However, to make accurate calculations about the stars, one must assume the…

degrees below zero, which is very cold compared to here on Earth. Pluto is so far away from Earth that scientists know very little about what the mysterious planet it is like. Pluto’s orbit is 5,913,520,000 km from the Sun.…

whatsoever. This leads to the rightful questioning of whether the world is flat or spherical, as an explorer who really was not at all, Christopher Columbus,…

Creation vs. Evolution By: Benjamin Garcia How did the earth and all of its inhabitants come to be? This is a question that has puzzled humans for ages. There are two main theories that explain how the earth was formed. These are the theories of evolution and creation. The most accepted creation theory is the one of the biblical creationists. Did a big explosion occur, setting everything in order and providing an atmosphere suitable for life, or did a creator lovingly design us along with…

period of rapid change in the earth system (Björck, S. (2007)). This included; the onset of the younger Dryas cold reversal, which saw the return of glacial like conditions across the northern hemisphere and megafaunal extinction, where 35 genera of large mammals became extinct across North America (Firestone et al., 2007). One possible explanation for this change is the Younger Dryas Impact Hypothesis (YDIH), which proposes that an extra terrestrial (ET) object hit the earth 12,900 years ago…

There is only one key difference between a planet and a Dwarf Planet. To answer the question of what a dwarf planet is we must realize what a dwarf planet is not. A planet is defined in three ways, 1. It is in orbit around a star, 2. It is spherical, 3. It is not a satellite, 4. It has cleared the neighborhood around its orbit. A dwarf planet must follow steps 1, 2, and 3 however they do not follow number 4. To clear the neighborhood means to clear the area around its orbit. When they were…

But Jupiter probably causes convection deep within Jupiter’s liquid layers. Jupiter has a huge magnetic field, much stronger than Earth’s. Jupiter’s magnetosphere extents more than six-hundred fifty million kilometers. Jupiter magnetosphere is not spherical. Jupiter's new belt is approximately…

People have got dreamed about going to Mars practically since it was discovered. In the foreseeable future, such mission is actually seems like real possibility. National Aeronautics and Space Administration (NASA) is taking the helm of one of the most significant human endeavors to explore Mars. Unlike the previous programs, Manned Mission to Mars is a one-way ticket. Scientific and technological challenges facing the mission to Mars have been identified as a result of strenuous scientific…

terrestrial and jovian planets. They are different in their position, composition and other features. First of all, let us see what are the jovian and the terrestrial planets. Jupiter, Saturn, Uranus and Neptune are the jovian planets. Mercury, Venus and Earth are the terrestrial planets. One of the main differences that can be seen between terrestrial and jovian planets, is their surfaces. While the terrestrial planets are made of solid surfaces, the jovian planets are made of gaseous surfaces.…

bright as me! Moon: Okay, when you come to visit me, you will be quite surprised with all my wonderful features! Yes, I may be small compared to planets, but I can be just as cool as them! I do have gravity, just not a lot. Compared to your home, Earth, I have about a sixth Earth's gravity. So when you walk, it will feel weird but it is so much fun! It's like you are on a giant trampoline! My surface is covered in thousands of craters, some big and some small. They are fun to explore. When…
