What is Gravity, how does it come about.

Imagine space as two-dimensional.If space is flat, any linear motions will be seen as linear motion, and there observable consequences. The axioms of euclidian geometry are dependant on flat space. However, if you bend the 2-d space, you change the properties of the two dimensional space. For example, in flat 2-d space, the angles of triangle add up to 180 degrees. However, if you were to curve the 2-d space, this is no longer true. If you curve the plane into a sphere, or at least in that direction, the result is that the angles of a triangle add up to more than 180 degrees. You can also bend the sheet in a open saddle geometry,the angles add up to less than 180 degrees. In both of these cases, the shortest distance is no longer a straight line, but a curve. The same idea is translated to 3d space. Light follows the curved path of a gravity well because that is the shortest distance.

By dem folks what do explainin'!

Lucid.

Would a list of physicists specializing in gravtional theories be better? I know people like Einstien, Wheeler, and Hawkings, who spent their lives researching this field this might not be enough. So feel free to contact the thousands of other physicists who work in this field. Or speak with numerous astronomers and cosmologists who deal with gravitional theories and how it affects large scale structures in our universe.

*Shakes Vbird violently*** Out with it Man!!! what is gravity!!!! what do you know!!!! spill it already!!!!!

They all use space-time as a construct, something to give our minds eye to view.Space-time is the form of maths to hang Relativity on.No one I have ever met except 'amateurs' believes that 'space' gets bent... only the signals [energy] are bent.To believe that 'space-time' has any form of material existence is akin to believing in aether or flogiston.Energy needs no 'medium' to allow it to cross the huge distances between the stars and us.

I believe you are once again misrepresenting your views as being part of mainstream physics. You have likely met very few people, if any, who accept your views on physics. Are you here to discuss some neat speculative possibilities, or to be cryptic so you can taunt people who think you might be saying something meaningful?--Percy

I am not, I am merely pointing out an error in the 'vox populae' of the masses, because a lot of people repeat a falsehood, it will not make it real.Please read the link...http://www.ling.su.se/staff/hartmut/uhr.htm

In particular this catches the eye...''Some further confusion has been caused by the widespread practice of referring to the pseudo-space-time of Minkowski just as "space-time". This misleads one to think of it as a four dimensional manifold with three spatial dimensions to wich time is added as a fourth dimension. However, the fourth dimension in Minkowski space-time does not represent any real 'time', but an imaginary one, while the other dimensions are the three real dimensions of space.''Please trust me on this, space-time really is just a construct, it works only because it gives form to something much harder to comprehend without it.

You MUST read Minkowski to understand how 'pseudo-space-time' is just a tool.

Conclusion?It's a grid.A grid in four dimensions, just like a graph is a two dimensional construct to allow you to plot movement, say a single point on a wheel, which when plotted forms a sine wave.Now what is bent in that graph?Is it the x and y axes?No.It is the path that is distorted not the axes...The same applies in the Universe with energy, the grid remains un-bent or bowed, what is bent is all the stuff that you impose on the grid... the axes [all four of them] remain constant.That is why it is relativistic, it only works for a single view point of that grid.

Before we go too far we must all agree on certain things about gravity.First we must separate it from 'G-force' or powered acceleration, that of say a motor car or fair-ground ride.They are similar but NOT the same thing.Yes?Gravity acts on a body unlike anything else in that accelerates the body uniformly, we see this on earth as 32.1ft per/sec/sec.Yes?Gravity can 'bend' any energy anywhere in the known Universe.Yes?Gravity 'appears' to be associated with mass in some way.Yes?Gravity is an energy of some form.Yes?Please take the time to read and agree/disagree with the above.

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.

Errr, he did separate them, he just didn't know the mechanism, we now do.Acceleration is the effect of power [energy] applied to a resisting surface or body. Your car accelerates because power is sent to the wheels and then to the road which resists its' turning, a rocket uses its propulsion against the resistance of the atmosphere and gravity to accelerate to E.V.What is 'deformed space'?[This message has been edited by V-Bird, 03-30-2004]
