Element 18001 "reactium"
Lets suppose that someone created element 18001 (although it would only last less than 1 microsecond), an alkaline metal. Noting that Cs reacts twice more vigorously than Rb and Rb twice more vigorously than K, would element 18001 be thousands of times more powerful as Cs?
Atmospheric overheating
I just realized something. The shell can initially start cone shaped, but during reentry, the shell will become overheated and stretch into an oval-spherical shape. That would definitely produce horizontal blast force (no wonder Saddam was pursuing this so much). Also...
Imagine a theoretical scenario where an artillery 3.5m across and 150m long is built underground (its possible, according to a science magazine). A 20 ton tungsten shell is fired into orbit and strikes a target thousands of miles away. Since the escape velocity is 30000km/h, assuming that the...
