Science does not seek to prove anything

2019-07-02 18:57:34 UTC  

😫

2019-07-02 18:57:40 UTC  

by prove I mean

2019-07-02 18:57:42 UTC  

Except I've already proven gravity, no need to fill out a chat particularly designed to be tedious

2019-07-02 18:57:44 UTC  

100% certainty

2019-07-02 18:57:53 UTC  

The theory made predictions and those were verified

2019-07-02 18:58:11 UTC  

Without our definition of gravity how could you explain all those phenomena

2019-07-02 18:58:14 UTC  

Density?

2019-07-02 18:58:17 UTC  

No one has proven gravity. No one knows what causes it

2019-07-02 18:58:45 UTC  

We know a whole lot about Density.

You cannot 'prove' anything with the scientific method

2019-07-02 18:58:59 UTC  

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.

2019-07-02 18:59:13 UTC  

But Mass to Mass attraction is an unproven theory.

2019-07-02 18:59:58 UTC  

@Rudi we do now what it is

2019-07-02 19:00:12 UTC  

The box model containing gas and the globular earth atmosphere are not analogous models

2019-07-02 19:00:13 UTC  

Gravity is simply the curvature of spacetime due to any nonzero value of the stress-energy tensor

2019-07-02 19:00:32 UTC  

Yes but he is probably asking 'why is that the case'

2019-07-02 19:00:35 UTC  

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.”

@Steve Angell atom inferometer, Schiehallion experiment

2019-07-02 19:01:02 UTC  

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

2019-07-02 19:01:38 UTC  

You can ask 'why' about literally anything and reduce it to some fundamental physics question without a satisfactory answer

2019-07-02 19:01:48 UTC  

At some point your dealing with philosophy and epistemology however

2019-07-02 19:01:52 UTC  

...

2019-07-02 19:02:19 UTC  

See, all the physicist who say that are likely talking about the issue of quantum gravity.

2019-07-02 19:02:40 UTC  
2019-07-02 19:02:41 UTC  

But that's irrelevant to our discussion because of the fact that it only involves the case were gravity is non-renormalizable.

2019-07-02 19:03:16 UTC  

Gravity has a perfect defined cause and effect and it's explained via a theory that can make predictions of phenomena we should observe.

2019-07-02 19:03:28 UTC  

We've observed such phenomena as direct results of gravity.

2019-07-02 19:03:44 UTC  

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.
https://www.nasa.gov/centers/goddard/about/people/RSimmon.html

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.
https://earthobservatory.nasa.gov/blogs/elegantfigures/2011/10/06/crafting-the-blue-marble/
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.

2019-07-02 19:03:51 UTC  

And gravity has still not been proven no matter what you say

2019-07-02 19:03:53 UTC  

Without gravity a lot of modern calculations would just break (rather, the gravitational constant)

2019-07-02 19:03:55 UTC  

This is how general relativity was explicitly proven.

And link/video spamming is extremely annoying to debate with.

2019-07-02 19:04:09 UTC  

If it had you would point us to the evidence

2019-07-02 19:04:28 UTC  

globies have no proof of anything

2019-07-02 19:04:28 UTC  

Flat earth

2019-07-02 19:04:39 UTC  

Earth is Mostly flat
