According to a large number of internet prophets, the coming solar eclipse will bring terrible destruction.

That they have been wrong about all their previous predictions of doom doesn't bother them at all, after all you just need to keep doing it and one day you'll be right and then maybe you'll get laid. That's the essence of contemporary online prophecy.

Thus saith the LORD, Learn not the way of the heathen, and be not dismayed at the signs of heaven; for the heathen are dismayed at them.

- Jeremiah 10:2
