      My understanding is that the tools that are used to observe it cause the wave function to collapse. Like how putting a thermometer into meat to check the temp makes a little hole.

        Yep! The only way to “see” a photon is to actually absorb it. You can’t just detect it as it goes by, it has to be absorbed and reemitted, and that has an effect on it.
