Macroeconomics First pass
The event sending the rock has already occured and we have no means to know if we are in its path. What can we do about it? How significant is our existence? What does knowing this mean for us?
I cant even begin to ask the questions to make sense given the scenario, however we can model all our risks using known and measured parameters.
That is exactly what Microeconomics is like. Understanding what can be measured, measuring it, understanding the limits of the measures and trying to guage what happend and what might happen.
whew! that was a wild one was'nt it?
