General relativity

Something pulls at my heart when I look into the stars. Something in the great beyond pulls at me, calling me, begging me to claim it as my own. Something in the great nothingness that envelopes our tiny planet is beckoning me. Maybe it’s nothing. Maybe it’s a fool’s hallucination, the manifestation of a child’s dream. Maybe it is a call that was meant to be answered by men and women far greater than I’ll ever be. Maybe the signal got lost on it’s way to find Earth’s next great hero and instead…

Introduction- In theory, parachutes work because of the force of gravity. Gravity is a force of attraction between two objects, that is highly affected by size and proximity (gravity will have a stronger pull if the object are larger and close together). Gravity also differs from the mass of an object the more mass an object has the more gravity it will exert on the objects around it. When looking at really large masses, like the earth the gravitational pull becomes much greater because of its…

There are at least one hundred billion galaxies in the observable universe. The first galaxies formed around 13.5 billion years ago after the big bang and the dark ages. NASA states that, “After the Big Bang, the Universe was composed of radiation and subatomic particles.” There are two theories about what happened next. The first theory is that small particles slowly team up and gradually form stars, star clusters, and eventually galaxies. The second theory states that the universe first…

Albert Einstein was one the most important scientists of his time. Mostly because of his discoveries and theories.Two of his theories have caught my attention: the theory of relativity or the theory of gravitation. I have found his works to be entertaining and educational while also being realistic and inspirational. Albert Einstein was a brilliant mind in his time. Well into the 21st century, he still continues to teach and give insight on important matters such as studies on gravity and…

One of the topics that captivate people's attention the most is the universe moreover where it originated. It is amazing to think that from the Greek empire to modern society, humans still have not figured out fully how the universe came to be. There have been different theories concerning the formation of the universe, but the widely accepted theory in today's society is the Big Bang theory, most scientists support this theory as there is substantial evidence backing it. Georges…

Interstellar: Black Holes Jodel Erickson May 15, 2017 Mr. Kopanke Apa Scientific Understanding of Black Holes “A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape” (Dunbar, 2015). This occurs because there is matter being pressed into a small space. Some black holes are the results of dying stars. Black holes are invisible because no light can escape. But, scientists have space telescopes with special instruments can…

1. What are Kepler’s 3 Laws. Explain each law in detail and why it is important in astronomy. (3 pts) Kepler’s Three Laws that everything orbits the sun. The first law is that everything orbits the sun, all the planets orbit in the ecliptic of the sun which clear up a lot of the problems with the tycho model in retrograde motion. Ellipses. The second law is equal areas in equal times. Equal Areas. And the third law is the mathematical relationship equating distance from the sun, average…

Background Gravity/Freefall: Every object on the Earth’s surface is pulled towards the center of the earth by the force of Gravity. Gravity causes all objects in Freefall to accelerate downwards at the same rate, regardless of the object’s mass. On Earth, acceleration due to gravity is constant of 9.81m/s^2. Therefore on Earth when air resistance is not present, all objects fall at the same acceleration of 9.81m/s^2. However, on the planet Vela Rani, the value of acceleration due to gravity is…

Goal The goal of this experiment is to verify Newton’s 2nd Law of Motion. Introduction Newton’s 2nd Law states that when an external net force acts on an object, the acceleration of the object is proportional to the net force, and it also occurs in the same direction. The acceleration is also inversely proportional to the net force. Thus, the net force, which is the sum of all the forces acting on an object, is equal to the mass of the object multiplied by its acceleration. In this experiment,…

Michael Shermer is an American science writer, historian of science, and founder of The Skeptics Society. Shermer is the author of books which delve into the ideas and beliefs behind UFO sightings and paranormal claims. One article regarding ‘The Flake Equation’ goes further into the topic of the paranormal and extraterrestrial life. Shermer did not create the equation himself, but rather discusses it regarding his studies and beliefs on a scientific level. The original equation, The Drake…
