Cosmology Cosmology Cosmology has always been an interesting area of study for me. For as long as I can remember, every time I look up at the night sky, a million questions pop into my head. Questions such as ?Is there an intelligent life out there ?How large is space, does it expand infinitely, if it does, what does it expand into These and many other questions still plague my mind. We can define Cosmology as the study of the heavens as a whole, including theories about its origin, evolution, large-scale structure, and future. I would definitely agree to this description, and would like to explain my point of view of the topics that Cosmology covers. Personally, I tend to believe that the big bang theory may have an explanation for the current state of our universe. The idea that all of this exploded from a super mass isn't too hard to believe. It gives good reason to the expansion of the universe, and the 360degree view of the universe (this because the explosion would have sent mass outward in every direction), but I wouldn't think of it as the origin of the universe. I mean, in my mind, something had to be there to cause this super mass. Was the universe contracting until it formed this huge mass? I believe that we may never know how the universe came about, rather have some idea as to what came directly before it's current state as well as before that and so on. We could come up with ideas until we die, and someone would just continue in our footsteps. I do have one idea as to how this super mass which is the being behind the big bang theory came to be one mass. Scientists as well as philosophers and just about anyone you tal k to can tell you that the universe is still expanding today, possibly because of the big bang. Though no one could tell you how this super mass came to be, or how it originated. I believe that there is a never-ending cycle of the expansion and contraction of the entire universe. The universe as we know it now is in a state of expansion. Though there are millions of gravitational fields out there opposing this expansion. What if there came a point in time where the force of expansion (caused by the big bang) exhausted itself and the forces of gravity took over and began contracting the universe back towards a center of equalized gravity and into a super mass? (You could probably find a mass in the universe today that is the largest and has the strongest gravitational force of any other mass, and name that the possible center of a new super mass). We would then have an answer to the theory of a big bang, and there would definitely be chaos in the distant future of Earth. Though, we s till would have no idea how any mass was formed, nor how it appeared in space. There is also still the question of space, what is it, what is containing it if anything, how did it come about? And many more questions like that. Maybe all of these questions can be answered with death. They could be answered by proving the existence of God and asking these questions. I personally believe in God. I want to tell myself that there is a being that gives us some direction, while giving us free will to a certain extent. And while watching over life, takes care of the universe. With all this belief, there is still a question in my mind as to what came before anything and what came before that and so on. It's like the question of the chicken and the egg, we could go on forever and still not be certain which came first unless we get into evolution, but I'm looking for the principal of the thing. This is why I believe that some things may be infinite. As far as infinity is concerned, I believe t hat such a phenomenon exists, I mean how better to explain many questions about the universe? I want to believe that somewhere, somehow there is a beginning point for
