Even If Aliens Exist, They Probably Won’t Affect Our Lives (And It’s Mostly Because of Physics)
The Fermi Paradox and the Future of Humanity: Why Interstellar Distances and the Laws of Physics May Mean We are Effectively Alone in the Universe Most of us have two alien stories running in our heads at the same time. One story is the honest, scientific one: Is there intelligent life out there? With so many stars, so many planets, and so much time, it feels like the universe should have produced thinking beings more than once.
