What is Gravity, how does it come about.

There is no gravity, much like there is no spoon. There is only straight-line motion through curved space.How could shooting a particle at an atom move it towards you?Particle conceptions of gravity are deeply flawed. Only bent spacetime removes the contradictions of gravity. (See, I can get dogmatic, too.) Errors? Or observations? Your position contradicts observation, therefore it is rejected.[This message has been edited by crashfrog, 03-30-2004]

There's no such thing as "force", only particle exchange.Gravity makes no sense as a particle exchange, but only as curvature of spacetime. Since we observe the effects of gravity, and since gravity can only be curved spacetime and not a particle exchange, and since there's nothing else gravity could be, we know that spacetime exists, because we perceive effects of its curvature.Your position is, again, refuted by observation.

My, aren't we clever. How long did it take you to Google for that little rejoinder? I'm cut to the quick, I must say.

It's my understanding that it curves into additional dimensions that we can't percieve. Or at least, that's how it's explained.

By dem folks what do explainin'!

You're in a soundproof rocket with no windows. You're either sitting at rest on the Earth's surface or you're accelerating in space at one g. How do you tell the difference?Moreover, if Einstien couldn't, how do you expect to?There is no difference between gravity and acceleration, because gravity is acceleration caused by deformed space.

You didn't answer my question. Take your time. Rockets push against the atmosphere? What kind of horseshit is that?[This message has been edited by crashfrog, 03-30-2004]

Are you familiar with Newton's laws of motion? Because you don't seem to be. What differences? The rocket is soundless and has no windows. There's nothing that can enter the rocket except for gravity. It's exactly the same.

You still haven't explained how you tell the difference. And your insistance on two separate forces that have exactly the same effect is becoming pretty comical. The gravity experienced on the Earth's surface (at some specific reference altitude, I'm sure) is exactly one G, because that's how a G is defined.You're trying to tell me that one isn't equal to one? By all means, keep talking. Maybe some sense will come out.

Let's see if yours is, via multiple choice:9.8 m per second per second is equal to:1) 10 m per second per second2) 8 m per second per second3) 9.8 m per second per secondThere's no difference between the units used for gravity and the units used for acceleration - it's meters per second per second in each case.If you answered anything but 3, send back your diploma - you didn't earn it.

I'm happy to answer any relevant questions you care to ask, to the best of my limited knowledge. So far, few of your questions have been relevant. The presence of mass distorts space. Straight-line motion through warped space appears curved to observers in the universe. Duh. Obviously not. But one atm = .987 bar. That's the same quantity expressed in different units.Ok, here's my three:Does 1 g = 1 g?How would you tell the difference between acelleration of one g and gravity of one g acting on a space capsule with otherwise no connection to the outside world?Why the fuck are you bringing up pressure in a discussion of gravity and acceleration?

Cite, please? Note that "your ass" is not a convincing citation.How would you detect these effects inside the space capsule? Assume that it's large enough to contain any equipment you like so long as none of the equipment penetrates the capsule.

You mean your bullshit? I thought you were kidding. You're serious?Please, try again.

You're right, I did. The table wasn't exactly clear.Revised figures: 1 atm = 1.0132500 bar = 14.6960000 psi.Same pressure measured in different ways. So obviously different numbers.But acceleration and gravity are the same thing measured in the same units. So 1 g = 1 g. It's lunacy to conclude differently.9.8 m/s^2 is 9.8 m/s^2 no matter what you measure.

How about you just tell me, Dr. Mysterious? Or don't you even know?
