Before our universe was created there was something that had happened to have created the universe. The big bang theory was a major part of why the universe was created. There are so many things that had to be contributed to the big bang theory. We don’t really know what will happen to our universe in the future but we can make predictions about it and we can use evidence and justifications to predict what will happen.
The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it talks about the universe as we know it starting with a small singularity, then inflating over the next 13.8 billion years to the cosmos that we know today. Because current instruments don't allow astronomers to peer back at the universe's birth, much of what we understand about the Big Bang Theory comes from mathematical theory and models. Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background. The phrase "Big Bang Theory" has been popular among astrophysicists for decades, but it hit the mainstream in 2007 when a comedy show with the same name premiered on CBS. The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment.
There are many misconceptions surrounding the Big Bang theory. For example, we tend to imagine a giant explosion. Experts however say that there was no explosion; there was (and continues to be) an expansion. Rather than imagining a balloon popping and releasing its contents, imagine a balloon expanding: an infinitesimally small balloon expanding to the size of our current universe. Another misconception is that we tend to image the singularity as a little fireball appearing somewhere in space. According to the many experts however, space didn't exist prior to the Big Bang. Back in the late '60s and early '70s, when men first walked upon the moon, "three British astrophysicists, Steven Hawking, George Ellis, and Roger Penrose turned their attention to the Theory of Relativity and its implications regarding our notions of time. In 1968 and 1970, they published papers in which they extended Einstein's Theory of General Relativity to include measurements of time and space. According to their calculations, time and space had a finite beginning that corresponded to the origin of matter and energy. I also know that there was a Big Bang is the fact that as things are moving closer to you the waves get compressed and as they are moving away from you the waves get stretched out. With light the shorter waves are the blue and the longer ones are the red and the further away a galaxy is the more red shifted it is indicating that the galaxies are all moving away from each other indicating that the universe was once much smaller and that at one time it was a singularity, which expanded until it got to the size it is today.
We may still be far from answering the question “what is the future for our universe” but we are at least able to predict certain possibilities. In our current view of the Universe there are 2 possible futures from studies. One possibility is that the Universe will come to an end in the opposite of a Big Bang called The Big Crunch. There is enough matter in the Universe eventually gravitational forces will…
