Here's a guy who got in serious trouble for the radical act of... looking. Galileo built a better telescope, pointed it at the night sky, and reported what was actually there.
What was there broke the official story. Moons going around Jupiter — so not everything orbits Earth. The phases of Venus — so Venus orbits the sun. The Earth wasn't the centre of everything. Copernicus was right.
The Church told him to stop. He didn't, really. So they tried him, made him publicly take it back, and locked him in his house for the rest of his life. The story goes that as he rose from recanting he muttered 'and yet it moves.' True or not, it's the perfect line — reality doesn't care what you're forced to say about it.
That's why he matters when you're lost. He's the patron saint of 'look for yourself.' Don't take the handed-down version. Go see. The universe is more honest than the people explaining it to you.
