@LatinRiteMass. I don't call myself anything--Dr is an academic title given to me.

This concerns not belief but science. Apparently, you don't know the difference. And I never mentioned what I believe, so your comments are little else than presumption.

@LatinRiteMass There are facts worth knowing in this life, and facts worth waiting for in the next (eternal). I don't think all the saints knew the spherical/non-spherical shape of the earth, and they most definitely focused on different things in their lives. Facts of the Faith are most important. If you turn out to be the saint known for spreading the fact that the Earth is Flat to the world, then I commend you for it, but please don't accuse me of sin for acknowledging that there are more important things in life, and trying to steer away from the sin of curiosity-which is a sub-vice of sloth. Some Dominican saints had very different ideas and views on the world than the Franciscans, same with the Benedictines-otherwise there would not be several different orders. Some saints married, others hermits, monks and cloistered nuns, this is analogous to that. Point is, your situation differs from mine, and this is not a matter of Faith and Morals, and most definitely not a matter of Doctrine.

@LatinRiteMass With all due respect, my instinctive response to you was one of two: For what doth it profit a man, if he gain the whole world, and suffer the loss of his own soul? Or what exchange shall a man give for his soul? (Matthew 16:26)
or You'd rather ignore doctrine, The Passion, the lives of the Saints, and philosophy, and find time for this? What is of higher priority?

However I think you misunderstand me. In my life, in my station of life, it is far more beneficial to me (though I would argue anyone) to contemplate the things I listed, than the subject on this video. Curiosity can be sin, and my experience of debating with myself for several years over geocentrism vs heliocentrism, and creationism vs evolution, I have seen myself spend more time than beneficial on those topics, and in the process lost or nearly lost my prayer life, and knowledge of the Faith. In which case I find debating flat earth a near occasion of sin, and something that I should avoid.
No man can know every detail of the world, and most especially of the spiritual world-which I'd prefer to keep my eyes set on as my goal. We still are discovering new animals within the world, and I am not a biologist by trade (though I do indeed love the topic) so I needn't be searching myself for that new species.
I would rather spend my time contemplating things of Faith during my free time than to know and learn worldly things.
