Krish Patel Ms. Justice Writing 2-1 19 December 2017 The Expansion Of the Universe Introduction The rate of the universe’s expansion is increasing and it started all the way at the birth of the universe. The latest studies suggest the expansion has reached a rate faster than the speed of light. The purpose of this research is to provide better understanding of the expansion of the universe. Questions can be answered. Why are all of the gravity bound systems being pulled apart from each other? How does dark energy impact the expansion of the universe? The Mysterious Force that Controls the Universe Why are all of the gravity bound systems in the universe being pulled away from each other? The observable universe is defined as a spherical …show more content…
Astronomers have been attempting to predict the future of the universe for years. The latest evidence points to the existence of a mysterious force known as dark energy. Our latest evidence points to dark energy winning the first Friedmann equation(“Basic”). The universe is not dense enough to cancel out the force of dark energy. This would mean the equation would be positive and the universe would expand forever. The right side of the equation should also be positive but the right side of the equation represents something totally different the universe’s spacial curvature(“Why”). This part of the Friedmann equation is controversial but the general consensus due to the latest research is that the figure k changes the shape of the universe. If k=1 all triangles are greater than 180 degrees, if k=-1 all triangles are less than 180 degrees, and if k=0 than all triangles are equal to 180 degrees and the universe is flat and all triangles are equal to 180 degrees. Scientists realized that to balance the equation they needed to add something dark energy. In the Einstein Field equations there is a sign known as a cosmological constant. This number does not change due to the expansion of the universe because its a constant. If the left side of the equation is subtracted from the cosmological constant the equation it helps the density term balance the equation to zero. The density in this equation decreases over time until …show more content…
