General relativity

permeated the universe in the first moments of its expansion. The most amazing thing is that a few years before Hubble's discovery, in 1922, the contours of the expanding universe have already been identified in the calculation. Based on the general theory of relativity. In the past there was an explosion of the space itself, after which the world began to expand, swell like…

One can take for granted the knowledge that has already been discovered or they can look back and learn about the people who made the discoveries in their lifetime. There are lots of theorists, who have furthered the development of nursing theory. Each one has contributed to the development of nursing knowledge that is used, event to this day (textbook chapter 5). Throughout this paper, different nursing theorists will be discussed, as well as, their theories; an application to the nursing…

entering a black hole and wearing a watch, the time will pass normally on that watch as it always had. Although our watch is ticking at a normal rate, someone else would see a different ticking rate on our watch. This difference in time is explained by relativity and gravity. The movie Interstellar is the first movie in the history of cinema to show time dilation correctly. When Dr. Cooper and Dr. Brand landed on the planet revolving around the black hole, their clock was ticking at a normal…

The History of the Development of the Four Fundamental Forces Nature has a total of four fundamental forces. The forces include gravitational, electromagnetic, strong nuclear and weak nuclear force. Gravitational force is the force of attraction between all masses. Every object in this universe is pulling upon other objects. Many scientists came up with logics to explain the science behind gravitational forces. The first one to try was Aristotle in around 330 BC. Aristotle believed Earth and…

In the m9c free fall acceleration lab we were to determine if mass or distance of an object falls effect on gravitation acceleration that the object experiences. The experiment was used to investigate the theory weather the heavier the object that it is will fall faster or not. The method that was used to find gravity was through the derived version of kinematic definitions. The overall result in the experiment concluded that distance and mass does not effect on the gravitational acceleration…

Noah Yeasted A black hole is a large amount of matter in a small space. Black holes are one of the things that can be left over after a larger star dies. The other thing a larger star can become after it dies is a neutron star. A white dwarf is created after a smaller star dies. The only way for a star to become a black hole is if the star was 10-15 times more massive than the sun. The diameter of a black hole is approximately the diameter of New York City. A black hole’s gravitational pull is…

For 13 years, the scientists of LIGO—the most ambitious, and expensive, project in the history of the National Science Foundation—had been waiting. LIGO, the Laser Interferometer Gravitational-Wave Observatory, has been twenty-five years and more than half a billion dollars in the making. It involves 900 scientists and engineers, including many whose entire careers have been spent designing, building, and preparing to analyze data streaming in to LIGO. Their goal: To confirm, once and for all,…

Best phrased by surgeon, author, and inventor Leonard Shlain in his book, Art & Physics, “Revolutionary art and visionary physics are both investigations into the nature of reality.” However dissimilar Vincent van Gough’s Starry Night may seem from Isaac Newton’s second law of motion, according to Shlain, this is what fundamentally unifies the two subjects. Physics is the study of the natural world, while art is the representation of it. Art has been part of our culture longer than any of the…

The Multiverse Theory is one of the most talked about theories in the modern age. It entails how there is a chance that we are not the only universe in existence but rather there are tens of thousands of other universes. This leaves all kinds of possibilities to the imagination; maybe someone was born with red hair rather than blonde, maybe someone became president rather than a physics professor. There are an infinite number of possibilities which causes the Multiverse Theory to also be a…

Nuclear Fusion and the Remains of a Dead Star Throughout the history of Earth, multicellular organisms rely on one thing, the sun. And throughout the observable universe, there are million of stars out there just like our sun. These stars could be different however, with either more mass, volume, heat, etc. In our high school career, we learn a lot about astronomy, such as the order of the planets in our solar system. We also learn about gravity, rotation of planets, and how long it takes…
