This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

This is true on earth. If you have objects of the same shape and different weights and you drop them from high enough to reach terminal velocity, the heavier one will have a high terminal velocity through air and reach the ground faster.
The "in a vacuum" thing is where this goes wrong, but I don't think homeboy really knew about space or vacuums.
no. Gravity is consistently pulling at 9.85m/s regardless of the size or density in an object.
Terminal velocity is reference to the air resistance and buoyancy affect on an object in freefall. This has nothing to do with the mass or size of the object, but it's air resistance.

Gravity is (mostly) consistent across the planet and will always pull the same force regardless of the object in question.

You did a google search and just pasted the top link? which is a question about calculating the drag on a falling object.
But you clearly didn't read the responses, which the first once directly states that the original question misses the premise that it is drag on an object from the atmosphere which causes the affect of different speed. This is the same arugment you made about terminal velocity. It's the same point. Terminal velocity and the speed slow down of two different objects is still directly related to the atmosphere and it's affect on an object.
While this is true, We circle back to the fact Terminal Velocity isn't a measure or an affect of mavity but atmospheric influence on the falling object.
Earth Gravity is consistently pulling on the objects of difference mass at the same velocity. given zero resistances, both would hit the same speed.
