Gravity is one of the

''Four Fundamental Forces" of the Universe,

The children's version, for you personally:

Curvature is built into EVERYTHING, which is why longitude and latitude are used to navigate the planet. Everything uses them. Hikers, bicyclists, autos, trucks, boats, helicopters, planes.

They all use them, and they've been in use for 300 years to move around and mark spots on the planet.

Longitude and latitude are a member of the family of measuring methods known as the ''spherical coordinates.''

You will not escape this;

you will not escape that they can only be used on spheres.

You will not escape that they are only accurate of a sphere of a specific size.

You will not escape that 12 and 14 year old boys get badges in learning about it.

You will not escape that the autopilot on a modern jetliner uses them.

Every word you've spoken is wrong.

Gravity's speed is expressly rated at 32 feet per second, per second.

Up until terminal speed created by the presence of the atmosphere,

an object falling, move 32 feet per second faster, than it was moving by the end of the previous second. This acceleration alone is evidence of a force or objects wouldn't fall toward the surface of the planet.
