Essays on Gravity
Gravity is an invisible force that holds everything in the universe together. It affects every living and non-living thing on Earth, from tiny particles to large planets. Gravity is a fundamental force of nature that keeps us firmly grounded in reality and ties our Solar System together.The effects of gravity are often taken for granted because they are everywhere around us ” we don’t even need to think about it when walking or jumping. But without gravity, life as we know it would not exist. Gravity helps keep the planets, moons, comets and asteroids orbiting their host stars; it also keeps the air we breathe up here on Earth’s surface instead of evaporating into space; and most importantly provides a force which allows us to stand upright. But what exactly is gravity? How does it work? To answer these questions, scientists have studied this universal force since ancient times. They have used mathematical equations to describe its properties and behaviour, such as Newton’s Law of Universal Gravitation which states that any two particles will be attracted towards each other with a gravitational pull proportional to their mass distances between them squared (F=GMm / r2). In modern times, Albert Einstein developed his General Theory of Relativity which further explains how gravity works by describing how matter curves spacetime around itself due to its mass ” creating a gravitational field or ‘well’. This theory has been tested extensively over time showing remarkable accuracy – helping scientists better understand black holes, neutron stars and cosmology at large scales. At the end of the day though ” no matter how much science can tell us about gravity ” there’s still something magical about being able to feel that mysterious tugging sensation whenever you step outside on a clear night sky looking up at all those distant stars knowing full well your own little planet is held together by this invisible power called ˜gravity.
Various steps follow the demise of stars of low stellar mass, medium stellar as well as those that are very massive. First, for the low mass star, the helium fusion leads to the formation of carbon core. The carbon core collapses but at a low temperature not enough to allow fusion of carbon. The outer […]
SpaceX is an American based space manufacturer and transporter company situated in California. It was founded in 2002 by Elon Musk with the primary goal of making technologies that will ease costs incurred during space transportation as well as enabling exploration into planet Mars. SpaceX is developing various space vehicles such as the Falcon 1 […]
White holes are hypothetical objects found in the space. They are celestial hypothetical objects from space that expands and emit energy. Generally, white holes are the inverse of the black holes. For black holes, no matter is allowed to escape from their space while the white holes erupts mass as well as energy and therefore […]
The Hayden Planetarium and the exhibit show give an overview of the birth of the universe. The Planetarium Theater and the Universe exhibit show a different array of sizes in the universe which leads to the timeline of the Universe from the Big Bang to the present. In this paper, I will explore the Hayden […]
