The Earth Is Concave

Flat Earth landed on my computer screen at the end of December 2016. I must not be the only one in this case to have had my YouTube home page flooded with videos selling me that the Earth is a dome-covered disk of glass sailing in the universe.Today when I write these words I wonder how I could believe for six months all this. And yet so. Hard as iron, to bawl with everyone, to want to impose this idea, as if I had made a flight in MIG to support this delusion.This delusion why? Because all of this is science fiction, it's inconceivable and it's an extremely powerful and powerful psychological operation. I will say even dangerous to the mind.
