A problem I often run into is that some people just assume their "common sense" concepts are right and anything else is nuts.

I must admit having "common sense" problems (or at least I use to -- I don't now) with the idea that matter has the effect of "warping" the space-time around it, so that the earth orbits the sun because of geometry, not force.(Of course there is the alternative quantum particle exchange view, but I only mention this so as to keep someone from "correcting" me).

The common sense view is of a force -- an invisible hand that reaches out from the sun and holds the earth in place. I can see why Newton was criticized -- what is this hand that does its thing through the vast emptiness of space?

Something people won't admit is that the universe was not designed, and if it was designed, it was not for our benefit in understanding it. That we can't understand something -- even if it seems outrageous and we can't see how it could possibly be -- is not grounds for dismissal. It may be grounds for demanding extraordinary evidence, but even here we need to have the humility to accept the verdict of the experts.
