Gravity isn't a force, it's a dip in space-time. If you experience the 'force' of gravity, you're just sliding in the dip. That's why Newton's formula F = m * a (Force equals mass multiplied by acceleration) works when you're calculating the force of gravity on an object. a = 9.81 m/s^2 here. You're just accelerating down the dip

This image uses a 2D raster to explain. Notice how the dip is down (in the 3rd dimension, while the raster is 2D) Real gravity works just like this, just in the 4th dimension, which is quite impossible to visualize.


I know I am confusing. Ask questions.
