The US Navy Rail Gun can aim at a target 100 miles away, with a laser and hit it with a projectile that moves at Mach 7, (ignoring the fact that the target would be a mile and a quarter below the horizon).
Forget sniper bullets, this is absurdly impossible on a spinning globe... anyone care to check my maths?

This is a rhetorical meme. The supposed “curvature” would already makes a railgun useless. At 100 miles there’d be a curve between it and the target of over 6666ft. It couldn’t see it and it can’t shoot through the earths curve if it was there. The fact is, it isn’t there. There absolutely no measurable curvature anywhere on earth in reality. That’s why a rail gun is so effective,The fact that they claim Coriolis affects a bullet, but doesn’t effect a railgun would be laughable. As well as an airplane would also be affected by Coriolis, if it existed . It doesn’t.
This is the same reason why a periscope works, because there’s no curvature. If there was it would be useless....
