DID ANYONE HEAR A BANG? 
Okay, this will be one of the few areas where we discuss pure theory of
astronomy. Eventually when you examine the Universe you have to say, "Ummm,
excuse me. Where did this all come from?" RISEC does not know. No
one knows. There are only theories and ideas. Mathematicians and philosophers
have all discussed the idea. It's still one of those questions that aren't
able to answer. We may never have and answer.THE CURRENT THEORY Scientists are currently working with the idea that the Universe started with all of the mass in one big ball, billions of years ago. One day we suppose, that ball exploded. From that moment, time as we measure it began. The moment when this big ball exploded is called the Big Bang. The idea discussing the explosion is called the Big Bang Theory. After the explosion, all of the dust and pieces began to spread out. As time passed, small pieces attracted other pieces and objects began to form. Eventually there were stars, systems and galaxies. The important thing to remember is that this is a theory, an idea. No one has concrete evidence that this ever occurred, but it is the idea we currently use to explain the origin of the Universe. How did all the stuff get in a ball in the first place? Good question. ABOUT THE PICTURE Space may have started with one huge amount of mass. Scientists theorize that the mass exploded in the Big Bang. This is a photo of a nebula. Take a look at the huge cloud of dust and gas surrounding the star in the center. |
