Consider the research question, "How many communicable civilizations are there likely to be like us in the universe?" If a student claims, "Given the proliferation of nuclear weapons and our inability to prevent catastrophic warming of the Earth's temperature, I don't expect humanity to last for more than a few centuries more. Therefore, I think it's very likely that we are the only communicating civilization in the galaxy that exists right now." Change the limits on the lifetime factor L in the spreadsheet to run a simulation with this more pessimistic estimate. Does the distribution of simulation results support this student's conclusions? Explain your reasoning and provide specific evidence to support your claim
