My theory is that the earth is flat, and that space is curved.
And my best approximation of that space curve is a toroid.

If you take a laser level, and go any distance, you find that the earth doesn't curve at all. Not even a little. So, either the earth is flat, or light follows the curvature. (or the earth is flat in a curved space)

The thing about the flat earth theory is that it basically throws out science. If this one block is removed from the foundation, science just falls over. Light, gravity, distance,

The trouble with science is that it has been taught as a religion. You know the darwin fish vs the jesus fish. And so, when one religion crumbles for you, you often search for another.

And, you are correct, what is happening in Antarctica is of extreme importance. But, again, what is there will destroy science as we know it.
