ok ok if you control gravity, specifically, you can affect bullet drop rate over distance, but you can't just fucking STOP A BULLET IN MID-AIR, forward momentum is separate from gravity

That depends on what it means to "control gravity." If I can create a gravitational source in the bullet's path that's strong enough to "grab" it, I most certainly can stop it in mid-air. If all I can do is turn up Earth's gravitational field in a localized area then not so much.

Yeah, the latter; the former is really more of a generalized mastery over force and acceleration.

The physics of simple ballistics/bullet drop are one of the most everyday things that you can use to show people how utterly unintuitive the world is when you pay attention. :) Mythbusters even actually replicated "fired bullet/dropped bullet hit the ground simultaneously."

That I'm guessing?

No, that is a related experiment where they fire a projectile with muzzle velocity X out the back of a vehicle with velocity -X and see what happens. As expected the projectile drops straight to the ground.

now I want to know what caused the 39 ms difference. does the fired bullet actually generate a little lift? was their timing mechanism not perfectly synchronized? what did it?
