Vortex Theory is the Best Way to Look at History

I think that the Vortex theory is the best way to look at history. The theory is that, like a vortex, everything in history grows, and then shrinks, going from big, to little, back to big, shrinking, etc. The Roman Empire is an example of this. After the Roman Empire fell, Europe went into a very uncivilized time period until the Renaissance. Another example is the United States. We have grown exponentially since declaring our independence. Some people may argue that we are starting to lose control of our country. History also repeats itself, meaning that these kinds of events are going to happen again and again and again.
