How as an individual can I know if the Earth is a sphere or a flat disc? What experiment can I do that doesn't involve trusting information from a 3rd party that would prove what the geometry really is?

As we say here (and I said it before): Don't trust verify.
Get your own rocket, fly up, take a pic... then show and PROVE the earth is flat and you can end this silly debate
