We possess something that we see as free will but it's really a function of conscious belief based upon nothing more than the quantum nature of something called Heisenberg's uncertainty principle. This uncertainty principle says that, at the subatomic level, it is not possible to know simultaneously with the same degree of accuracy, both the position and velocity of a particle moving through space-time. That uncertainty factor is a true part of reality both at the quantum level and even at the larger classical level of reality. Human consciousness lies right there at the threshold that divides the quantum world from our more familiar reality based upon the laws of classical physics. Well, what people perceive as free-will is just that uncertainty principle as it applies to our invdividual timeline from birth to the grave.

Its an odd question but today in my history class we talked about how the great empires or countires in history have never lasted. So i was wandering if the United States could ever fall and if yes why?

The problem is that US economy depends on imports and cant pay. But that's just one part of the whole deal.
The US is just not able to continue on its own, the US is part of the "New World Order". Technology is its main tool to control, manipulate and create confusion.

"…During the 1980s and early 1990s, the National Weather Service installed Doppler radars around the USA. In addition, some television stations have their own Doppler radars, while others use images from the NWS radars…Scientists and forecasters have learned how to use these pictures of wind motions in storms, or even in clear air, to more clearly understand what's happening now and what's likely to happen in the next hour or two"

"…The …Radar map shows areas of current precipitation. A weather radar is used to locate precipitation, calculate its motion, estimate its type (rain, snow, hail, etc.), and forecast its future position and intensity. Modern weather radars are mostly doppler radars, capable of detecting the motion of rain droplets in addition to intensity of the precipitation. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather. Precipitation type is indicated by the color - green is rain, pink is a mix of rain, freezing rain, sleet, and/or snow, and blue is snow. …Digital radar systems now have capabilities far beyond what their predecessors only dreamed of. Digital systems now offer storm tracking surveillance. This provides users with the ability to acquire detailed information of each storm being tracked. Storms are first identified by the radar by matching the raw data received from the radar pulse to some sort of template, preprogrammed into the system. Once the storm is identified; speed, distance covered, direction, and Estimated Time of Arrival (ETA) of the storm are all tracked and recorded into a memory location of the radar in order to be utilized later. In order for a storm to be identified it would have to meet the definitions of a storm, as programed by the manufacturer. Otherwise, any cloud could be mistaken for a storm. Usually the storm must show signs of organization. The storm must have a core or a more intense center to be identified and tracked by digital radar tracking systems…."

It almost seems impossible to even fathom the idea of creating our current technology from nature.

Everything is "made" by nature. Without the alloys and materials needed to make the processors and chips in our computers we wouldn't have them. Without electricity a natural form of energy we wouldn't be able to power our electronics. Rubber used to come from trees, we've just modified it. Glass used to me nothing more then heated sand. Synthetic materials are all just a conglomeration of naturally occurring materials that would have never actually combined in nature. If nature can make something as perfect as a crystal clear diamond that is nearly unbreakable, then there is no limits to what nature can make.
