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…

radiation would also have been continuing to move away faster from us that the wavelength from this radiation would have been moved from being visible light to the CMB we see today. One of the major pieces of evidence for the big bang theory is that galaxies appear to be moving away from us at speeds that are relational to their distance. This piece of evidence is known as “Hubble’s Law”, and this phenomenon was discovered in in1929 by Edwin Hubble. His observation supports the expansion of the…

Given the fact that the Earth is just a minuscule portion of our galaxy and at least one pulsar is able to be detected is astonishing, let alone over 1,000. To date a total of about 1,800 pulsar stars have been identified and astronomers are continuing to search for more. While the discovery of pulsar stars is are significant…

the poles of a collapsing star, these are formed from very intense explosions in distant galaxies. GRBs are the brightest known electromagnetic events in the universe. They can last just a few milliseconds, or hours. The burst is often followed by an afterglow, which is emitted at longer wavelengths. We have been able to learn a lot of what we know about GRBs from afterglow. We can measure how far away the galaxy that the GRB came from is by the afterglow. GRB’s are commonly formed when a high…

the night sky, little glowing dots are scattered across the night sky. They are known as stars. There are several billion stars in our galaxy, but only a few are seen with the naked eye. Stars are by definition, large exploding balls of gas made up of mostly hydrogen and helium. The two most unstable elements on the periodic table. The largest star in our galaxy is the sun. It’s the largest star and one of the few stars that are going through a star wide nuclear reaction. The reason the sun has…

The universe is an infinitely growing sphere which is calculated to be 46.5 billion light years in diameter. This sphere contains the space in which billions of stars are contained. Some of these regions have small rocks called planets. Humans inhabit one of these planets which is instilled in a perfect system called the solar system. However, mankind may not be the only ones to have a system in which life can thrive on. There may be others that live in their own planets like us. In fact, some…

process in the universe able to produce this much energy (Bhat, 2011). Additionally, if a GRB was able to distribute itself in all directions equally, such as the way a star does, its luminosity would be that of the combined brightness of a million galaxies such as our Milky Way, albeit briefly (Bennett et al.,…

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…

24,500 lbs. NASA launched Hubble in 1990, it was "named after Edwin P. Hubble, He was an astronomer" (Rosario). Hubble is a traveling telescope it traves around the Earth taking pictures of planets, stars, and galaxies. "It has seen stars being born and stars die, and it has seen galaxies that are trillions of miles away" (Dunbar). Furthermore, Hubble can see space better than telescopes on Earth can, it's a different kind of telescope than one would usually use, you don't look through the…

It essentially started the motion of the rearrangement of the kosmos into the way it is today. The way we see the galaxy right now, was because of nous all those years back. It acted as an energy of sorts that helped create the kosmos and is still very much present in modern times today. Therefore, I absolutely agree with what Anaxagoras said about nous and how it’s…
