Dark energy

Energy is a mysterious and everlasting component which exists within the universe; it is the existential source of power which human beings have harnessed through technology in order to progress and evolve. It is fair to note that energy is quintessential to every action and reaction occurring in the universe at all times. Furthermore, the law of conservation of energy states that energy cannot be created nor destroyed but can be transferred between different forms and states and even between objects. The transfer and application of energy to technology is a power human beings have been wielding and harnessing for years. Moreover, there is still so much to learn in terms of energy acting within the universe. Every day human beings continue…

Dark Matter and Dark Energy Casson VanDervoort Northview High School  Dark energy and dark matter are commonly found to disprove common knowledge in the world of science but still, these two forces are unknown and untapped. Both dark energy and dark matter are commonly referred to as one another but, in fact they’re different. The two are mostly found together but, dark matter may have been found to be linked to primordial black holes. One may ask, “What is dark matter and energy and…

What are Dark Matter and Dark Energy? Introduction: To start with, Dark Matter is invisible material that permeates the galaxies. It exerts a gravitational influence on the stars causing them to deviate from Newton’s and Kepler’s laws. Dark Matter also affects members of a group of galaxies. The nature and composition of the Dark Matter are unknown. In space there is a lot of totally empty space, the vacuum, which contains energy. This energy is variously called Dark Energy and also may be…

The great Neil deGrasse Tyson once said something along the lines of humans have only discovered about 4% of the universe. Not only does my fear of what I don't know going on below my feet in the ocean scare the crap out of me, but that big star filled sky does as well. It doesn't just scare me, but it probably scares and excites scientists studying it all over the world. Since we only know a fraction of the inter-workings of the universe, there are many questions and things going on that we…

and effects of such expansion in the universe are addressed to create a deeper understanding of how we can learn from our past to better our future. One of the most profound questions that baffled scientists for generations was, does our universe end, and if so where. Here, the theme of expansion first emerges in the story of Big Bang cosmology. As soon as scientists realised that the universe was not static, they immediately understood that it was in fact expanding, and that once in the past,…

Objective Description In the year 2000, the American Museum of Natural History posted an essay as an online resource, Profile: Georges Lemaître, Father of the Big Bang. An excerpt from Cosmic Horizons: Astronomy at the Cutting Edge. It was edited by Steven Soter and Neil deGrasse Tyson. The profile begins with a simple explanation of the expanding universe and how Georges Lemaître published his mathematical findings that today we know as the Big Bang theory. Soter and deGrasse Tyson provide…

Marie von Ebner Eschenbach once said, “In youth we learn; in age we understand.” I agree with this quote. During youth we learn and experience a lot of our “firsts.” Our first word, first steps, first bully, first fight, first kiss, first relationship, first love and first time. Thus, when we get older we evolve and understand more of what life is and what is expected of you. Though I am merely fifteen years old and haven’t graduated high school yet, I’ve matured and have learned from my…

The following paper is on each of four subjects: black holes, dark matter, dark energy, and the multiverse theory. The first subject is black holes, which are regions of space having a gravitational field so intense that no matter or radiation can escape. Their existence is greatly debated over, and it still has not been determined whether they exist. The second subject is dark matter. Dark matter is a placeholder that cannot be seen. It accounts for 27% of the matter in the universe, but like…

have two distinct phrases come to mind: Dark matter and dark energy. From being mentioned in groundbreaking scientific journals and television and movie series’ to even this essay you are reading, dark matter and its existence has made quite the impression on scientists, documentarians and aspiring students.…

Nevertheless, the existence of dark matter has been widely accepted henceforth, and research into it is ongoing. Astronomers have recently discovered a galaxy without the existence of dark matter(Shelton). Dark matter cannot actually be seen or detected itself, but, as Zwicky found, it causes immense levels of gravity. This newly discovered galaxy has only the normal amount of gravity you would expect to find due to its stars, planets, and general cosmic junk, unlike every other galaxy we’ve…
