I investigate, and the sign turns out to read, "Galileo Interviews." I say to the other person waiting for the elevator, "That's interesting." He says, "What's that?"

I say, "A sign on a door at a Catholic university that says, 'Galileo Interviews.' That could go all kinds of places, some of them not very good." He laughs. The elevator comes. We board. I smile and go on, "Well, you know what I say to that? 'Si eppur su muove.'"

He looks confused. "What is that, Latin?" I say, "No, it's Italian. It's what Galileo said after he was forced to recant by the Inquisition." "What does it mean?" "But still it moves." The elevator arrives. We debark.

To be completely honest, he probably did. He was kind of a jackass. He was still right, though.

we didn't have astronomic observations to support the idea until Brahe IIRC hunch before that

Brahe was already dead by the time Galileo was active. Galileo outlived Kepler by quite a few years, and both of them made observations that conclusively disproved the geocentric theory. The Ptolemaic system was observationally discredited by then.

perhaps I am thinking of Kepler? It's not that the evidence was solidly for the Ptolemaic model as that we hadn't really proven heliocentricity on the evidence yet. Recalling from an article I read awhile ago.

Kepler had Brahe's data and used it to derive the laws of planetary motion. He also observed the phases of Mars IIRC. Galileo observed both the phases of Venus and the Jovian moon system. They had tons of observational evidence.

Kepler had Brahe's data, but he performed multiple mistakes in the math. I was literally reading this just yesterday. Not sure which of the textbooks in the bathroom it was in - maybe https://www.amazon.com/Fundamentals-Astrodynamics-Dover-Aeronautical-Engineering/dp/0486600610 … but I think actually a different one

Nobody’s perfect. :) But the main point, that nobody was working from a hunch, remains true.
