The power of science is the idea that specific outcomes are repeatable—that hypotheses can be tested, proved, or disproved.

We are frequently confronted with opposing viewpoints on knowable things. It's the entire premise of sports betting. We each think a different player will win, but only one of us will be right.

In sports, we say "scoreboard!" to remind each other of the empirical truth vs. our subjective opinions.

I can't stop thinking about Rosetta: a spacecraft launched from Earth in 2004 that landed on a comet about 590 trillion kilometers away ten years later, after getting a gravity assist from a few planets along the way. Insane.

Only science could have made that happen.

When deciding which of two truths to believe, look to the results. Look to the scoreboard.
