> core of science is repeatability
It is indeed. But with experiments and theories getting ever more complex and difficult to verify [1], we are edging towards just having to believe what we are told. Verifying Newton's theory of gravity was relatively simple, just throw stuff from your balcony and verify that s = 1/2 g * t^2!
So we are deep inside the second Middle Ages, where the priesthood tells us what to believe and how to behave, without us having any chance of verifying their claims.
I greatly wonder if and how humanity will get out of this one, and what a second Age of Enlightenment would look like.
