Center Of The Universe Force Of Gravity
1,271 wordsThe human conceptualization of the solar system dates back to the beginning of time. The early Egyptians worshipped the sun as a source of life and then the area called space was becoming a curiosity to humans. Throughout history, our knowledge of the solar system has increased and there is still much to learn. Through the research and studies of Brahmagupta, Ptolemy, Kepler, Brahe, Copernicus, Galileo, Newton, and Einstein. With this knowledge, laws and equations for physical science have been ...

Billion Years Ago Solar System
2,233 words... alvarez's case, and see if it was flawed. This job was turning out to be more fun than I had expected. On my second reading of Alvarez's letter, I found it particularly dubious that the Cretaceous and Eocene extinctions should be excluded. How do we know that asteroids do not hit the Earth periodically? I asked. Maybe our failure to arrive at a theory just meant that we hadn't been clever enough. Not finding something is not the same as proving it is not there. I decided to reserve judgment....

Liquid water cannot exist on Mars's surface because of the low temperature and pressure' water exists only as ice deposited at the poles and perhaps trapped below the surface and as vapor in the atmosphere. Mars is very desolate and barren and is covered in craters and are prone to violent sandstorms. The UV radiation of Mars would kill any known life. Mars has the largest ...

1,582 wordsHumans live on a small planet in a tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single brilliant star-the sun. The solar system is the earths neighbourhood and the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto are the Earths neighbours. They all have the same stars in the sky and orbit the same sun. Scientists believe the solar system began about 5 billion years ago, perhaps when a nearby star exploded and ca...

Or can they force themselves to think, that the wise Creator has disposed of all his animals and plants here, has furnished and adorned this spot onl...

A man named William Herschel first discovered this mysterious planet in 1781, he was a German musician living in England who had a great interest in Astronomy. He believed the sky held secrets he wanted to know. He couldnt afford to buy a big telescope, so he made his own. One night in March 1781, Herschel was studying constellations of Gemini. He sp...

1,728 wordsThere are nine planets in our solar system and we have visited all of these but one. Even though Pluto is the smallest and furthest planet from the sun, it is no way inferior to the other planets. It in fact is possibly one of the most unique bodies in the solar system. There is much that we do not know about this tiny world and its equally unique moon, Charon. For this reason we are proposing to send a flyby mission to the Pluto-Charon system as soon as possible. Pluto was discovered on Februar...

Since electrons are negatively charged, the entire xenon atom becomes positively charged and therefore ionized. These ionized particles will now fly out of the back of the spacecraft at an incredible rate of more than 62, 000 miles per hour! The xenon ions would be going in the opposite direction of the craft. Due to Newton's third law, which was discussed above, the spacecraft will b...

Comets are small, fragile, and irregularly shaped. Most are composed of frozen gas. However, some are composed of frozen gas and non-volatile grains. They usually follow very strict paths around the sun. Comets become most visible when they cross the sun. This also applies to people who view comets with telescopes. When a comet gets n...

For most of this time lack of knowledge about the physical conditions in the solar system prevented a rigorous approach to the problem. Explanations were especially sought for the regularity in the directions of rotation and orbit of objects in the solar system, the slow rotation of the Sun, and the Titles-Bode law, which state...
