A much more stable position is for the ball to be down somewhere at the bottom of the valley. Whenever we encounter a finely-tuned physical situation, there are good reasons to seek a physically-motivated explanation for it. (LUIS ÁLVAREZ-GAUMÉ & JOHN ELLIS, NATURE PHYSICS 7, 2–3 (2011))When the Universe gives us clues, we ignore them at our own peril.When you approach the world scientifically, you seek to gain knowledge about how it works by asking it questions about itself. You observe its behavior; you perform experiments on it; you measure specific quantities that you’re interested in. If you ask the right questions in the right ways, you can begin to gain information about what physical phenomena govern the behavior that was revealed in each and every one of your investigations.Most of the time, your results will teach you something specific about the Universe. But every once in a while, you’ll find something that seems too good to be true. You’ll measure something that will confuse you in one of two ways: either ...
