The Big Bang Theory
1) About how long ago did the big bang take place? Around 13.7 billion years ago. 2) What is a black hole? Black holes are areas of intense gravitational pressure 3) Does the universe continue to expand? It continues to expand and cool to this day and we are inside of it: incredible creatures living on a unique planet, 4) Was there really a big bang? No, 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. 5) What light elements seem to support the Big Bang Theory? Finally, the abundance of the "light elements" Hydrogen and Helium found in the observable universe are thought to support the Big Bang model of origins.
