For those who still think gravity isn't a theory: what causes gravity?

Question

PROVE your answer. Don't just say relativity--relativity can't be proven.

I ask this because people on here still think gravity isn't a theory. Or they say "no, gravity is a natural law; thus it can't be a theory." The two aren't mutually exclusive..ahh, whatever. People, just answer the question.

Answer 1

Why is this in the global warming section?

Answer 2

Everyone knows that gravity is caused by global warming

Answer 3

It's obvious that gravity is the work of “Intelligent Falling”[1]!  There are huge gaps in our understanding of how gravity works. These gaps can only be filled by the presence of a higher intelligence.

In this peer-reviewed journal[2], physicist Jonathan L. Feng reports that gravity is the result of "extra spatial dimensions". What else besides the Intelligent Faller has extra-spatial dimensions?

Answer 4

With gravity one can make mathematical predictions, and get exact results.  With climate science that is clearly not the case. The only way they can get warming is by quoting only one source, who has at its head a politically driven man, who goes out of his way to rewrite history.

Answer 5

gravity is not a theory. gravity is a word describing two objects attracting each other.

gravity is caused by an atoms movement.

if every atom would sit still, the world would fall apart.

Answer 6

Again you can see and feel gravity. Just because you can't prove what causes it doen't mean it is not something tangible.

You don't have to believe in gravity because it affects everything you do, unlike your AGW which has yet to be proven.

Append:

I did answer the question. The cause of gravity cannot be proven just measured. I never said anything to the contrary. I concede the point the you are correct about gravity, not AGW.

I believed in it for a period, but my eyes were opened, and I now know that it is bunk.

That is the crux in the AGW theory, it can't be proven.

Answer 7

You have an extremely narrow understanding of science.

Gravity is a fact. It happens in a predictable, measurable manor.

You're just not smart enough to understand why. Their may be many theories on how it works, but it still works without knowing which theory is true.

You really need some education in critical thinking.

Answer 8

The 'skeptics' answers are exactly as I wolud have predicted - gravity is caused by....gravity.

In short, they have no idea what causes gravity.  Neither does anyone else (although physicists have much better theories than they've come up with).  This is why it's called the theory of gravitation.

Now, by studying gravity for centuries, we know a lot about it.  We know the gravitational constant of the universe, we know the gravitational constant at the surface of the Earth, we know how to calculate a gravitational force, etc. etc.  Thus we can make predictions as to how fast and object will fall, how long it will take to fall, etc. etc.  But we still don't know what's causing it to fall.  Thus it's still a theory.  For all we know, whatever is causing gravitation could suddenly shift states, and we could be repelled off the face of the Earth instead of pulled down toward it.  We simply assume that's not going to happen because it never has.

We actually understand global warming much better.  We know the various forcings which cause climate change - the sun, orbital cycles, the Earth's albedo, greenhouse gases, etc.  Because we understand these forcings relatively well, we can make predictions as to what will happen with the Earth's climate in the future.  The models are unanimous in predicting that the planet will continue to warm at a dangerous rate, and so far, the models have proven to be highly accurate.

AGW is a theory just like evolution and gravitation.  We understand these theories well.  Rejecting them just because they're 'theories' is ignorant.

Answer 9

OK when you tell me what causes gravity, I might believe you know exactly what causes warming.  In truth, there are theories about gravity waves and mass but noone can generate a gravity wave and we know very little about it.  This is a good example where people think they know more than they do and is therefore similar to global warming.  It is interesting that those that know  the least think they understand the most.

Answer 10

It hasn't been proven yet but I will not be surprised if the "gravitational attraction" of matter to other matter is really a by-product of the interaction between matter (made up of charges) and a sea of virtual photons (the existence of this photon sea is predicted by Quantum Electrodynamics).

A simple way to think about it is to imagine a solitary piece of matter in space. It would be bombarded from all sides by extremely low energy virtual photons, the sum of the momentum exerted by the countless photons would be zero. Now, if you introduce a second piece of matter, that piece of matter would scatter some of the photons that would have been incident upon the first piece of matter from the direction of the second piece of matter. This would lead to an imbalance in the momentum incident upon the first piece of matter and would yield a net force upon the first piece of matter in the direction of the second piece of matter. (Draw a diagram, if you got confused reading this.)

The main roadblock to scientists reaching this conclusion about the "cause" of gravity is their "belief" in general relativity. It is misleading them horribly. And the superstring theories are extensions of the same mistake introduced in General Relativity.

Incidentally, the property of matter called "inertia" will also be proven to be a by-product of the interaction between the photon sea and matter. That means that matter in the absence of the photon sea would not have any inertia. THIS would be the easiest prediction of "my" theory of gravity to test. And if it were observed, it would falsify Newton's gravitational model and Einstein's Relativity.

A room far below the surface of the earth is partially shielded from the photon sea that gives matter its inertia, so an oscillator with a known "mass" on the surface of the earth, should be observed to have less mass in a room far below the surface of the earth.

No scientific model should be "believed in" they are all by definition approximations of something in nature and as such are incomplete, imperfect. So believing them to be absolute fact is wrong. Just as believing any symbolic religious doctrine to be absolute fact is wrong.

Answer 11

I think you posted this in the wrong section. Last time I checked, gravity has nothing to do with global warming. Maybe you should try the science and mathematics section.

Answer 12

magnetic pulls

Answer 13

Gravity is certainly real. In your question, how would you explain a fallen object? We can eliminate magnitism, by using non metals. Gravity is the simple attractions of molecules at the lowest common level. Done....Next.

Answer 14

Sir Isaac Newton already did this.   He reduced it to an equation that can be and has been checked:

EDIT - and what causes it is described in the links: the mass of the objects that have grativational force.  

I'm not giving you much credit for wit - if you were Bob, I'd guess that where you were going was to point out that we have reduced gravity to a calculation based on mass, and similarly we've reduced the heat trapping properties of CO2 to a calculation, that can be verified in a closed experiment.

And my retort to that would be yes, all other things being equal, CO2 does trap heat, but not much heat, definitely within the "noise" of the countless other factors influencing climate.   I'd also point to past warming periods without "runaway" warming - where it got warmer than today but the methane wasn't released from either the permafrost bogs or under the seabed, as evidence that the present and projected levels of CO2 really cannot be viewed as a "trigger" that could unleash a 10 degree F increase in termperature beyond the present level, more like 1-2 max.
