You cannot 'prove' anything with the scientific method
But physicists think about gravity all the time. To them, gravity is one of the mysteries to be solved in order to get a complete understanding of how the Universe works. So, what is gravity and where does it come from? To be honest, we’re not entirely sure.

But Mass to Mass attraction is an unproven theory.
The box model containing gas and the globular earth atmosphere are not analogous models
Gravity is simply the curvature of spacetime due to any nonzero value of the stress-energy tensor
Yes but he is probably asking 'why is that the case'
Neil Tyson - What is Graity? On the most recent edition of his “Star Talk” radio show and podcast, astrophysicist Neil deGrasse Tyson answered the question, “What is gravity?”
“I have no idea,” he joked. “Okay, next question.” Then, he went on to explain, “Here’s the difference. We can describe gravity, we can say what it does to other things.” “We can measure it, we can predict with it,” he continued, “but when you start asking, like, what it is? I don’t know.”

which is a deeper question, but the fact we can't answer that doesnt mean calling gravitational fore the stress-energy tensor is a failed model
You can ask 'why' about literally anything and reduce it to some fundamental physics question without a satisfactory answer
At some point your dealing with philosophy and epistemology however
...
See, all the physicist who say that are likely talking about the issue of quantum gravity.

But that's irrelevant to our discussion because of the fact that it only involves the case were gravity is non-renormalizable.
Gravity has a perfect defined cause and effect and it's explained via a theory that can make predictions of phenomena we should observe.
We've observed such phenomena as direct results of gravity.
And have even made predictions and measured reality and observations to show our initial theory was accurate.
anyone here still think they live on a cartoon? - Robert Simmon - AKA Mr. Blue Marble
Data Visualizer and Designer Robert Simmon never thought that he would become “Mr. Blue Marble.”
My role is to make imagery from Earth sciences data. I turn data into pictures.

Crafting the Blue Marble
To make the Earth look realistic, or at least how I imagined the Earth would look, I needed to do some work.

Compositing separate images into a convincing whole is (of course) easier said than done. Even with control of each layer in my image processing software (Photoshop) it took hours of tweaking and re-tweaking transparency, layer masks, hue, saturation, gaussian blur, and curves to get an image that looked like the picture I had in my head.
Without gravity a lot of modern calculations would just break (rather, the gravitational constant)
This is how general relativity was explicitly proven.
And link/video spamming is extremely annoying to debate with.
If it had you would point us to the evidence
globies have no proof of anything

@Rudi gravitational time dialation, gravitational redshifting, gravitational lensing
Atom inferometer, Schiehallion experiment
Ample proof for you
Lmfao, I just named numerous proofs?
You send me videos and expect me to watch
I send you actual observation and expect you to at least research if you're unfamiliar
Gravitational time dialation- a measured time dialation due to the effects of the curvature of spacetime
more yadda yadda and no proof
Gravitational redshifting- the red and blue shifting of light as they exit or enter a gravitational well
Gravitational lensing- the bending of light due to gravitational effects
All of these were predicted by general relativity
