Technically all balls thrown are curveballs because they curve towards the ground.

Nope! Gravity causes space to curve. A ball that falls to the ground is travelling in a straight line through curved space.


I… you’re right haha fuck


Lol… the gravity curve. Haven’t thought about that since little league


If I understand the universe correctly, a baseball’s trajectory doesn’t actually curve towards the ground either. They travel in straight lines through spacetime and it’s the spacetime that curves.


No. gravity is why balls curve towards the ground, a curveball defies what one would expect of gravity to do to a ball normally, through manipulations of rotational gravity or artificial gravity, one changes how the ball reacts to actual gravity.
