Discussion – Tayla Dorrington Introduction There are 2 major theories about the universe and how it began. These are the steady state and The Big Bang theory. Both theories have an explanation on how our Universe is, how it began and how it works. Both theories have stuff in common but also have many differences that could completely change the way we look at the Universe. The Big Bang Theory has much more evidence supporting it, while the Steady State Theory has been proven wrong. Big Bang…

For devices on Nano scale classical physics usually cannot explain transmission of electron through the insulating barrier with higher potential energy than kinetic energy of the tunnelling electrons and in this case the Heisenberg’s uncertainty principle takes place. Barrier penetration can be explained from Heisenberg’s uncertainty principle: If we were to say a particle cannot enter a barrier, we would actually say this particle is not there, i.e. its position uncertainty is Δx = 0 in the…

too late. As you know, the galactic post office takes 1,000,000 years to deliver to distant galaxies. And since you all are getting further away, I am sorry if the letter does not reach you in time. The universe is changing. In fact, galaxies are moving apart at an ever increasing rate. The gravitational attraction between two galaxies at that distance is too small to have a significant effect, so the galaxies more or less follow the general flow of the expansion. I hope the best from all of…

The Solar System By Krishiv There is always something that you are pondering about. From the periodic table to the circulatory system. But did you know that the majority of people wonder about the Solar System? It is the final frontier, or the one thing that is not fully discovered. There are many unique masses in the Solar System. They range from planets like the earth to rocks such as asteroids, comets, and meteors. But one thing is for certain… every mass has to orbit the sun.…

many questions an average person would ask such as, How was the universe formed, how old is the universe, and will the universe expand forever? The universe is a huge wide open space that holds everything from the smallest particle to the biggest galaxy. Isn't that crazy? For the question many that many were asking, scientifically, about 13.7 billion years ago, a powerful explosion happened called…

NGC 584 is an elliptical galaxy in the constellation Cetus. The galaxy was discovered on 10 September 1785 by the German-British astronomer William Herschel. Number 20 in the Herschel 400 list is NGC 584. NGC 584 is a moderately large and bright elliptical galaxy in Cetus. In an 18 inch telescope it appears as an elongated patch of light with a bright center. The two bright galaxies either side of NGC 584 are the 13.2 magnitude NGC 582; (left) and the 15.2 magnitude PGC 1028168. (Right). While…

H-R Diagram Lab-Plotting the Stars Part I: Introduction 1) One method scientists use to measure the distance of the star is called parallax. Parallax shift is when closer stars shift positions against the farthest stars. In order for astronomers to measure that distance, they measure the distance of the shift, also considering the diameter of the Erath’s orbit. Then the angle of the parallax is measured. The smaller the angle of the parallax shift is, the farther away the star is from the…

To me, astronomy is the study of the universe and everything in it. This includes the planets, moons, stars, comets, etc. The major difference found between Muggle astronomy and Wizarding astronomy is that the Muggle world has "laws" that explain what they see in the universe. The study of these laws of the universe in the Muggle world is called "physics". Although these laws do explain a vast majority of what the Muggles see on Earth and in the universe, it may not hold true in the Wizarding…

as NGC 3031 or Bode's Galaxy) is a spiral galaxy about 12 million light-years away in the constellation Ursa Major. Due to its proximity to Earth large size and active galactic nucleus] or supermassive black hole), Messier 81 has been studied extensively by professional astronomers. The galaxy's large size and relatively high brightness also make it a popular target for amateur astronomer. Messier 81 was first discovered by Johann Elert Bode in 1774.Consequently, the galaxy is sometimes referred…

universe barren or teeming with life? The observable universe; the part of the universe from where the light has had time to travel to earth is approximately 90 billion light years in diameter. There are 20 billion sun-like stars in just our Milky Way galaxy and recently we learned that planets are much more common than we thought. Those are the planets which are situated within the goldilocks zone of its home star, where the temperature is just right for water to remain in liquid state and…
