But the truth is a lot muddier than that. The actual process of science involves tweaking your initial hypothesis over and over, trying to pull it in line with what we already know. It involves a leap-of-faith that when you formulate your theory correctly, the predictions it makes will be even more successful, across-the-board, than any other alternatives. And when things don’t work out, it doesn’t always necessitate abandoning your original hypothesis. In fact, most scientists don’t. In a very real way, scientific theories can never truly be killed. The only way they ever go away is ...
