Please learn to use EDIT function.

Remember this is flat earth thread, not crazy spinning ball madness.

Let all things here be done decently and in order.

Acknowledged and welcome aboard.

Hope you will enjoy your staying on still and motionless plane living environment called earth. 

Right then, let's go back to school.

There is a perceived difference between acceleration and velocity. Travelling 1 million mph feels the same as travelling at 1 mph. Forces only act when we change velocity.

Imagine a car crashing into a wall at 100mph. Until the impact, everything inside the car feels stable, you could pass a drink to another passenger without spilling a drop. But when the car hits the wall, everything inside carries on moving at 100mph towards the wall, making a big mess.

Same principle with the movement of the Earth through space, we won't perceive any forces acting upon us unless there is a change in our velocity.

After a person jumps up they get pushed down and not by some magical force called gravity but by the simple fact they're denser than air.

I'll stick with my gravity. Let the flat earth people stick with their density.     

Yay, voodoo physics.

WTF is "point source yellow?"

Of course Earth is flat. How can you say otherwise?

Only the Sun and Mo_On revolves around the Earth.

A point source would be a single 1000W light bulb vs. a diffuse source like an array of 20X 50W florescent tubes.
