Are we alone in the universe? As of now, yes we are, but we are spending lots of money in the search for intelligent life. Doctor Frank Drake came up with an equation that we can use to determine the likelihood that intelligent life exists. N = R* • fp • ne • fl • fi • fc • L is the famous Drake Equation. When the variables have numbers plugged into them, it becomes clear that we are very likely not alone. If in fact we are not alone, and they find us, will they be friendly? Stephen Hawking does not think so. Hawking has said, “We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet.” If a race of aliens is similar to us but more technologically advanced, we don’t stand a chance of survival if they come to Earth.
