Use the Drake equation to calculate the potential for intelligent life within our Galaxy. Your teacher may assign different numbers to use than the suggested ones in bold, or different groups may work independently with their own assumptions.
N = R* • fp • ne • fl • fi • fc • L
## Special Considerations:
In other words, during the life of the galaxy thus far, humans have had the ability to communicate outside our solar system for 100 years / 13.2 x 109, or, . Even if another civilization were contemporaneous with ours, they would have to be within 100 ly to have received our first radio waves by now. If they were 2,000 ly away, they would not receive our radio waves until the year 2300. Another consideration: without the ability to travel at or faster than light speed, the time involved would be many generations in human life spans. (Of course, perhaps these intelligent beings have already discovered how to use wormholes and portals to appear at our doorstep, for good, or, as Steven Hawking thinks, for bad!)
Calculate your OWN number for the Drake equation, using and justifying values that you deem appropriate. Then, discuss the chances that another species would have coincided with our current time line; include in the discussion the possibility that an extraterrestrial life form would be want to make contact with humans, and what that contact may look like. You may submit your answer as a file attachment or a text entry.
