The Fermi paradox simply postulates:
Where are all the dang aliens, dammit?
Of course more formally: one might expect
with the sheer number of stars out there, that
aliens should be all over the place. This becomes
ever more glaringly strange given the vast number
of exoplanets that have been confirmed.
The answer is simply logical:
Extinction events on a galactic scale.
Its impossible for us to know of the details of what
may be able to wipe out all major life-forms on a galactic scale.
But it does not take much thinking to see that
if some super-massive body went monster-nova
then it could just kill all major land-based life-forms at least.
But any big-energy event could do it.
The consequence is most interesting:
Other advanced life-forms would be about at the same
level of development as humanity.
The conquistadors might have considered something similar.
The answer for them was that all human civilization was wiped
out with the younger Dryas meteor impact in Greenland about
12000 years ago.
But that is another story.
Or is it?
Who are we on the galactic scale?
The adventurers who traversed the abyss?
Or did we practise ritual sacrifice (war) out of
a sense of complacency and hubris?
