Re: There is no drawing force
Hi Change of Pressure,
So I presume One Simple Principle » Esittely is your website?
Please do not cut-n-paste entire webpages as your response in an ongoing discussion, whether your own or anyone else's. The likelihood that something written for some other context is precisely the right response is remote. Write original words in your own prose that directly address the message you're responding to.
Frankly I think the language barrier will be too big an obstacle for clear communication. I'll try to give you a little leeway as you try to make constructive contributions and will monitor how things are going, but this last message from you doesn't provide much hope. It reads like utter nonsense, and we try to discourage nonsense here at EvC Forum.

Holy Crap
I am more confused after 6 pages. I know gravity is the "gluey force" which holds me to the ground.
But what the heck is it? Damnit I wish someone knew. Possibly it is God(the christian one) pressing lightly on my shoulders and every object which has mass moving through the boson field. This is the only logical conclusion I can arrive at as Brian Greene was also unable to explain it in layman's terms in his book Elegant Universe(he is smart)
Brian Cox could not even explain gravity in an articulate understandable method - look how pissy he gets:

Gravitational force = (G * m1 * m2) / (d2) that is what it is, correct? The method through which is works is simple 'God'. I know that is not true. But boy I wish I knew/understood.

Re: Holy Crap
Hi Purplebear,

Gravity isn't a "force." That is Newtonian physics, and about 100 years old, as a concept.
But what the heck is it? Damnit I wish someone knew.
I think you meant to say "damnit I wish I knew what it was."
Gravity is the effect of mass density curving spacetime. That is what gives the impression that it is an "attracting" force.
Here's a quick video that explains it with an easy to follow analogy.
Hope this helped,

Let me see. Einstein's theory of general relativity where he dealt with gravity was published in 1916. 2009-1916=95. Ok, you made it under the wire.

1915 actually, but it was November so I'll let you off

Gravity is the effect of mass density curving spacetime. That is what gives the impression that it is an "attracting" force.
A heavy object causes a dip(curving) - got it. A heavier object causes a deeper dip - got it. Mass Density is just an elitist way to calculate weight - got it.
Round object A(herein described as ROA) is placed on the skin of a massive drum and shoved to the center. Because of the weight of ROA it places pressure on the skin of the drum. Luckily the properties of the skin are elastic! The skin not wanting to break has only one other option give into the weight taking advantage of this elastic property and bends around(curves around) ROA in attempt to compensate. It works the skin dips! ROA puts pressure on the skin so ROA remains captured. Round Object B(ROB) is hurled onto the drum at 14,000 mph. Because of the shapely dip already created by ROA it desires to roll towards ROA. ROB understands moving down hill is the past of least resistance.
So gravity is caused because smaller objects desire to roll into holes caused by larger objects. Or they are simply forced to follow the decline. This desire expresses itself in waves which travel slower than the speed of light. These waves are what are responsible for not allowing objects that currently live on ROA or ROB float off into outer space. These waves are also what do not allow ROB to fall out of the smaller dip that has created for itself when compared to ROA? These waves also impact objects on ROA or ROB differently depending upon their mass. These waves eventually fade out or become weaker with distance. These waves also do not impact objects with little mass.
WAIT NO that makes no sense. Or I am misunderstanding. I thought you implied "Gravity is the pressure which is felt because an object is rolling towards a heavier one at the bottom of a decline". The earth is not rolling top over bottom obviously. North stays N and S stays south, correct? So rather than rolling perhaps better described as a skiier on a slope? I assume this non rolling has to do with spinning on the Axis. OK OK here is my confusion. If the earth is moving into the suns curve why does this wave formed by this pressure, press or hold me down? Pending where the earth was in orbit shouldn't it on occasion pull me forward on my face or back on my ass. I just jumped out the window of my home. I fell straight down I think. But the earth is moving down a slope on an angel. Why did I fall straight down? Why is it always perceived as "pulling down" or "pressing down".
You were right.... Since it is me not everyone who misunderstands could you explain? The information it provided did not help. I apologize possibly the way I articulated myself was lacking in clarity.
How does the effect of the earth falling to the sun make me unable to float like I could on the moon? I know when I turn a key in the ignition if functioning properly and all necessary materials and fuel are present the car will start. However, if your professor in physics class ask how does a car start and you tell him by turning a key. If your professor asks what is a car and you tell me steel, rubber and cloth put together in a building by machines that put forces here and there. It ought to be an indication you dunno.
Anyhow, I know it was my fault for asking the question incorrectly. I am look forward to your reply, Onfire!

You're taking the analogy too literally. The objects aren't really rolling, per se, they're just moving toward the lowest potential energy point. When you raise something above a massive object, it has potential energy, and as it falls, it uses that potential energy and comes to rest at a place of lower energy and becomes trapped there until more energy is imparted.
You fall straight down because you're falling down the potential energy well that the earth creates. Anything with mass bends space-time, even you and me. We're just so small, and gravity is such a weak force, that it's effectively negligible. The Earth, moon, sun, etc are all so amazingly huge that they have a noticeable effect on things around them.
So, the Earth is revolving around the dip the sun makes. The Moon is revolving around the dip the earth makes, and we're stuck down at the bottom of that dip, unable to get out unless we use a lot of energy to overcome it.
