What is Gravity, really?
Gravity is not curvature of space.
Really.
f=(e/c^2)a
Gravity is spacetime acceleration.
g=sta
Really.
Any questions?

Unca Cece: You list’nin?
This forum is a place where he OP asks questions to overcome his own ignorance, not a place to invite questions because you’re supposedly smarter than Cecil.
And I don’t think you’re allowed to link to other forums.
The first respondent to your question in the linked forum answered your question as well as anyone can; we don’t know what gravity is. That is to say, we can describe it in terms of the warpage of spacetime, and we can hypothesize (but cannot, with current means, observer) force exchange particles that are analogous to photons in electromagnetics or gluons in the nuclear interaction, but lacking a quantifiable theory of quantum gravity and a means to verify it, all we can do is mutter on a bit about “Higgs particles” and “topological quantum field theory” theory, and then stare bitterly into one’s beer while resenting the fact of being born about 50/150/1500 years too early. It’s a rough life being a theoretical physicist, which is why so many of them crack up and become wandering madmen. Well, that and it has better hours and working conditions.

Those two things you think are different, fundamentally aren’t.
So what explains the lunatic topologists waving knives in your face?
Edit: Bonus points for an answer involving hairy balls.
I would never assume to be smarter than Cecil. Or even a competent fifth grader.
The link shows I was told by authority that there are better forums if I wish to seek the truth. Thus I find my self gently knocking on your and Cecil’s door.
Speaking of fifth graders. I wish to know what the teeming millions know.
Assuming just the most basic understanding of Newton and Einstein and Al Gebra.
Can you prove force as gravity as ‘spacetime’ acceleration in five?
There are additional clues here. Yet please feel free to simply just ask for more.
…I will trust that Cecil will not allow dogma to rule over truth.
Truth speaks for itself, dogma censors and bans.

P.S. I believe Larne might take Fernanda’s name in vain. I will need proof beyond my reasonable doubt to believe she would hold dogma over truth.
Everyone, especially Stranger On A Train answered your question already. No one knows what gravity is. It is pointless to get into these types of details.
Please reread poster #6.
Yet this is exactly what the moderator would not admit. It is thus I find myself rudely censored and banned. It is thus I find myself asking you and Cecil for truth.
So please tell me shag and stranger. If given basic Al and Newt and Stein, is it that you deny or simply still cannot prove gravity is spacetime acceleration by massenergy (a.k.a. gravitylevity)? Denial is not the same as truth.
f=i=g
i=ma
g=(e/c^2)a.
Gravity is spacetime acceleration.
g=sta
Really.

Could you try making sense? I have no idea what you’re trying to claim or what you think your “equations” prove. This is the same kind of nonsense you got banned for posting on the other forum.
Spooky action at a distance.
rwjefferson, I’m just curious, because I spend more time studying language than physics and I’m normally good at these nuances, what your first language is.
Force is acceleration.
‘Mass curves atmosphere’ does not fully explain or predict
inertial force as wind.

I don’t see a question here other than in the thread title. Therefore, I will move this thread from General Questions to Mundane Pointless Stuff I Must Share.

There is no such thing as gravity. The Earth just sucks.
No, it isn’t. Acceleration is the action of an applied force upon a mass, i.e. Newton’s Second Law of Motion, F=ma.
I honestly can’t make heads or tails of the question you are trying to ask/debate/refute, or indeed, what “Denial is not the same as truth,” even means, much less “gravitylevity.” Your posts are about half a notch above TimeCube.com in clarity, only lacking the homophobia and anti-Semitism to rise to the level of true crackpotism.
Is there a Incomprehensible Questions I Must Ask After Being Rejected By Half A Dozen Other Forums forum, 'cause I think that is really the most appropriate in this case.

Well, nobody says it is, as has been pointed out already – but, as a matter of fact, it can be described astonishingly well using the mathematical concept of curvature, which really is just a measure of the underlying geometry – meaning, that in the presence of mass objects move as if space was curved, i.e. what we know as a straight line (the shortest distance between two points) in a familiar Euclidean context is generalised to a geodesic.
I’m confused as to how to picture this – so does a mass just accelerate space-time into its direction, causing everything else to be pulled along with it? What happens to that space-time, does it just kinda pile up in the centre? Shouldn’t at some point the accumulated space-time counteract the gravitational force? Or does it just vanishes to somewhere else?
If you’ve got two masses some distance from each other, would the space-time in between just get infinitely thin, or would new space-time be produced like new earth crust at the East Pacific Rise? If it gets thinner, shouldn’t the flow rate, and hence, the gravitation, over time become less? If new space-time is produced, is that process infinitely fast, i.e. could you accrete arbitrary high masses around some point and still have a constant flow? If infinitely much space-time can be produced in infinitesimal time, shouldn’t the universe ‘overflow’ and lapse into a state of effectively gravitation-free equilibrium?
Timecube - now that’s heavy!
Or is it just dense? Fizziks hurts my brain.
How many times must a question be restated before it qualifies as a General Question?
What is gravity really?
I am certainly glad Newton and Einstein did not feel the question to be pointless.
What is gravity really?
That is the simple question I wish better answered.
Really.
“We don’t know what gravity is.”
“No one knows what gravity is.”
“Spooky action at a distance.”
“Curvature of space.”
“It is pointless to go into…details.”
I will agree that the answer, ‘gravity is acceleration of space and time’ is so easily shown and obvious and mundane that it is pointless to deny. Yet still it is.
Denial is not the same as evidence other. Denial does not make a question pointless.
Still I will wait for evidence other.
Gfactor:
Now I ask please; for your best answer.
What is gravity really?
Please support your response with your best evidence.
Please reinstate this thread under general questions. At least, Cecil and I might wish to find even better answers.
What is gravity really?
Please support your response with observation as evidence.
I thank you in advance.

One more time, with feeling. Repeat after me: We. Don’t. Know. What part of that concept is so difficult for you to grasp?
