Fermi Paradox
Where is everybody?
TLDR above link:
Given a certain set of parameters based on Intelligent Life on Earth that get inputted into something called the DRAKE'S equation, there should be 1000 Galaxy spanning civilizations just in the Milky Way galaxy. But that begs the question: WHERE IS EVERYBODY?
Theory: There is a Great Filter that we are not taking into account that is either behind us, with us, or ahead of us that precludes a civilization from becoming one of the 1000. Behind us is good, with us makes for 'interesting times,' and ahead of us would kinda suck. Lots of theories on what the filters could be.
Earlier this month, a team from the Oxford University Future of Humanity Institute put out a paper stating that attempts to dissolve the Fermi Paradox by stating that the parameters of the Drake's equation are faulty and when it you put in actual realistic numbers into the equation, the likelihood that WE ARE ALONE is extremely high.
Thoughts?
My favorite video on the Fermi Paradox is an OLD TED Talk here:
