# What exactly is gravity?

If an object gets closer to the Earth, it gains weight. There is no "weight" outside a gravitational field.
Accelerating the object doesn't increase the weight. It just makes the weight gain happen sooner.
Inertial force is fictitious. There's actually no such thing.

I like your sarcasm! Of course I had considered that you were giving me more support in debunking General Relativity. Since inertial weight is considered to be real in Einstein's Principle of Equivalence. Never did Einstein refer to mass in his writings.

And the fact that you resorted to a Wiki article. The article is a complete work of fiction. And I know you know that.

Mass is not weight according to the way I was taught in school. I was given a set of equalities: Weight=Force=Mass x Acceleration. But I was never presented with proof that those equalities exist. Just accept it. I was taught that mass is a quantity of matter and its value is considered constant throughout the universe.

Then we come into the real world and things aren't quite adding up. For instance one kilogram is considered to be equivalent to 2.2 pounds. Of course that can't be true. Unless we all were lied to. According to my math 2.2 pounds is equivalent to 9.8 Newtons. But if you go to a balance scale you can prove that 2.2 pounds does indeed balance out equivalent to one kilogram. So what gives? I'll side with the actual observation. What it boils down to is Weight equals Mass. And the measurement is done using the force of gravity. Basically gravitational weight cannot be separated out into mass and acceleration. Since I already demonstrated that an object under gravitational acceleration is weightless. Acceleration and weight are two different things. An object on the surface of the earth is not accelerating. Yet it has weight. Now I did come across an idea stating that space is accelerating downward through objects thus creating an acceleration field. If that could be proven then time machines would be real and also space drives. Prove it first. I'm not a fan of "Assume it to be true".

Inertial force requires the presence of an opposing acceleration vector. Gravitational force does not. This is the primary observable fact that makes Inertial force and Gravitational force different from each other.
Thanks for clearing up the confusion on inertial and gravitational forces. Your calculations on weight equaling mass are very simple and I'm surprised to one else has done them. Mass may not be as important as people think. I'm also not a fan of assuming things to be true. Too many people do, and its limiting the flow of ideas.

Don't believe anything you think you know about gravity. It's all theoretical fiction. You can gather your own facts about gravity through direct observation. Direct observations do suggest our concept of mass doesn't apply to gravity.

All objects with gravitational weight have their weight vectors pointing toward the center of the earth. If you'll notice there is no acceleration vector due to the fact that gravitational weight does not rely on motion to create the gravitational weight. So Newtons law F=MA doesn't work with gravity. So inertial weight and gravitational weight rely on totally different conditions for their creation. These facts quickly debunk Einstein's theory of general relativity. The Equivalence Principle is not valid.

Then we have objects in gravitational free-fall. In a vacuum these objects accelerate toward the center of the earth in a weightless state. Again Newtons laws of motion do not apply. So gravitational weight and acceleration vectors do occur, but never at the same time. Both vectors point in the same direction but are temporally out of phase with each other. The time vectors for each would be described as 180 degrees out of phase between gravitational weight and gravitational acceleration.

If you'll notice, no concept of mass was needed to describe the way gravity works. Just observable facts.
Sounds about right, also there may be two parts to that force. What if gravity has a second component such as a push/pull effect? The weak void of space may also be a force? If we could rip a hole in the fabric of that weak force we may be able to overcome the pulling force known as we call gravity? Just a SWAG? • Einstein
