Objective Morality

My purpose in writing this is to argue for the existence of an objective morality based entirely on rational and scientific reasoning. By “objective morality” I do not simply mean that morality exists in the sense that various societies consider various actions to be immoral. What I mean is that certain actions are inherently right or wrong regardless of what any society thinks about them. In other words, I mean that there is an “objective morality” which exists independently of human beliefs and human civilization. There are many people who have the opinion that it is not possible to believe in such an objective morality without also believing in concepts such as God or an eternal soul. I believe that…

Dark Matter, Dark Energy

It is the intent of this paper to introduce the relatively recent theories of dark matter and dark energy and their relation to each other. These theories explain the observed increase in expansion rate of the Universe as well as explain why galaxies remain intact despite the apparent lack of sufficient mass to affect the gravitational forces needed for cohesion, especially when considering that galaxies rotate at speeds that should disperse their stellar composition away from its core. Dark Matter Dark Introduction Our understanding of the Universe is ever evolving as new discoveries are made, challenging what we have always believed. Some struggle to grasp an explanation of those new discoveries and the phenomena presented. These new discoveries are made possible…

Life Without Gravity

In a world without gravity, one would be weightless, but always nauseous. Because of this, it would be very difficult to complete a lot of your daily activities without throwing up. If you tried to eat something while you and your food are floating around, you will probably have a lot of trouble trying to hold your food down. In 0-g, life would be very hard. Roller coasters are a perfect example of this. I do not do well on roller coasters. I get sick when I encounter zero gravity for that split second on rides with loop-dee-loops and the like. This is how I know I would really suck at surviving if there was no gravity. Not only would…

Investigating circular motion

By plotting the graphs it can be observed the y axis is equal to v” and the x axis is given as r (radius), the gradient is given by (y2 – y1) / (x2 – x1). By working out the gradients it can be seen that the gradient for 50-gram masses is approximately 26, whilst the gradient for the 100-gram graph is approximately 53.27, approximately double the gradient of the 50-gram graph. It can also be observed the any two points taken for the 50 gram graph will have a relatively close gradient to any other two points, hence the graph has an almost constant gradient. The significance of all this will be discussed in the questions. QUESTIONS 1 What…

How gravity works

“Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is the attraction that exists between all objects”. (NASA gravity 2000) Gravity is a very essential part of life on earth. We are in the exact position in the sun’s gravitational field to keep us in orbit and keep life ongoing on our planet. Gravity is a downward force on any body of mass, the larger the mass of the body, the stronger the gravitational force. On earth the force is 9.8 N/Kg (Newton’s per Kilogram) roughly, depending on where you are on earth. Gravitation The original idea of gravity…

The Ordered Universe Assignment

1. Why was the Ptolemaic system accepted as an explanation of celestial motion for over a thousand years? What did it explain? What system challenged the idea that Earth was the center of the universe? The Ptolemaic system says that the Earth is the center of the universe. Everything else surrounded the Earth. The Copernican system challenged the belief that Earth was the center of the universe. The major difference between the Ptolemaic and Copernican universes is that the Copernican universe puts the Sun at the center rather than the Earth. Both systems both assumed that all orbits are circular though. 2. What were Tycho Brahe’s principal contributions to science? How did he try to resolve the question of the…
