But if you refused to accept gravity beyond what you could prove just by dropping items, you wouldn’t want to be in a plane over the ocean. Both inertial navigational systems and the GPS system have to account for relativity.
But we know that that relativity is either incomplete, or in error. Much of what you take for granted in the world around you relies on scientific theories, even one’s which we already know are not fundemental truth.
Theories are just that, a way of explaining the world as it measurably is. To be valid, it also must be able to predict outcomes. There is nothing to stop you from denying yourself a broader glimpse into the majesty of God’s creation. I like getting a tantalizing glimpse of a ‘hot jupiter’, orbiting a star which is staggeringly distant (

Or glimpsing part of our planet’s beautiful and awe inspiring past (

But you can certainly slap your head and shout ‘No No No!’. Ignorance may be poor citizenship, but it is a constitutional right.
However, assigning denial of the world as it is as a requirement of Catholicism is not an option. We have an Apostolic Church with the Gift of Authority. Not only has the rightful successor to Peter (two actually) accepted evolution as a probable truth, no Pope has ever asserted that belief in theories of evolution is in any way immoral or in conflict to Church doctrine (in fact, the Church has stated otherwise from almost the beginning).
The Pope is the ultimate moral authority on the matter and there is no conflict. The Church permits you to freely choose ingnorance, but not to contradict the moral or doctrinal authority of the Pope. At best that is heresy and schism, at worst anathema (see the Dogmatic Constitution of the Church, First Vatican Council).
Two other sidenotes: We actually don’t have as good a theory to explain and predict gravity as we have for modern genetics. If you can ‘prove it all day long’, you could be awarded a Nobel Prize.
And, genetics, an enormous body of evidence in favor of modern evolutionary theory, was principally the result of a Central European Monk’s work (Gregor Mendel).
