Since space only contains 1 main property distance, distance is the only thing that can be changed to warp or curve SPACE-time with the presence of mass. If mass causes Space distance to dilate or constrict it might explain a bit. Example: Let’s analyse Earth’s mass and what it’s doing to the space occupied and influenced by it. At Earths sea level = 6,378.13 km radius, example: space distance density would be dilated or constricted in a volume or area at the given radius. At sea level radius, 1m of space has a constricted distance of 1.0621m At sea level radius + 10m, 1m of space has a constricted distance of 1.0612m At sea level radius + 20m, 1m of space has a constricted distance of 1.0603m At sea level radius + 30m, 1m of space has a constricted distance of 1.0594m Etc… The constricted space distance values are just examples and not real space distance constricted or dilated values. The “changing space distance dilation” at different radius's is what “curved space-time” is mapping. You could probably work out the real values by using the gravitational time dilation at sea level = x then reverse calculate the amount to space distance dilation is required to slow the clock down by that of space distance contraction. This might be what is causing gravity! Objects located in “curves” are attracted / move toward higher space distance density areas or move down the curve...
Have you considered reading up a little on general relativity? You're sorta tryin' to reinvent the wheel here.
Gravity warps spacetime not just space. If just space was warped then a thrown baseball, a fired bullet and a photon would all follow the same trajectory.
BdS: General Relativity says that the TIME can also be changed. Hence "spacetime". I'm not sure that "distance" is a property of space, anyway. Well, it does. The general theory of relativity explains how it happens, quantitatively. Not in General Relativity. Curvature and distance intervals aren't the same thing. If you're going to use time dilation anyway, what's the point of your space contraction/dilation? I was under the impression your aim was to throw out time dilation. Okay. So you have an idea. I agree with DaveC that it looks a lot like you're trying to reinvent the wheel. We already have an excellent theory of curved spacetime. The task you have ahead of you, then, is to show that your idea leads to a more useful (or more correct) description of reality than Einstein's. You'll need to sort out the mathematical, quantitative formulation of your hypothesis next, then calculate some results that can be compared to real-world experiments and observations. That's what Einstein, and many who followed in his footsteps, did with GR. How far have you got so far in determining exactly how (and, perhaps, why) your distance dilation/contraction works, quantitatively? Does your theory have a set of axioms, for instance? Are there any derived results? Or are you just at the stage of imagining possibilities?
What properties does space have? So what is Curvature in GR and what is curving? To discuss how gravitational time dilation works with space distance density and how it might be what is causing gravity. Motion time dilation works differently. To explain how gravitational time dilation is being dilated physically through space distance density. Only trying to figure out how it works physically. Nope, I'm inspecting the wheel and trying to understand how it works. I know you guys dont need to because you know everything already. Pity nobody really understands it. Can you tell us what and how curves work? Nope, I agree his theories/models produces the correct results. I'm trying to describe how they work physically. Yes exactly like GR. I'm just trying to decipher its fundamental physical workings. I know you dont like to discuss things... Yes, I took advice from the best... Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand. -Albert Einstein
Yes he also published his general theory over 100 years ago which answers a lot of your questions. I would also check out Minkowski regarding space time and his treatment of Einstein's work. FWIR Einstein hated it but then came to accept it. He was a very smart man.
I have a suspicion that If Einstein knew what this quote would end up being used for, and mischaracterized as meaning, he would have never said it. For one, he had a disdain of "authority", and even said that the cruelest joke fate ever played on him was to make him one. IOW, he would not want anyone to follow what he said just because he said it. Now to the quote: While he said imagination is more important than knowledge, he did not say that knowledge was unimportant. To take a page from his own life, when he realized that he did not have the knowledge in higher mathematics needed to complete General Relativity, he went out and sought that knowledge. Imagination might have set him on the path, but he needed already existing knowledge to blaze that path to its end. The most imaginative architect in the world can't design a viable building without a knowledge of structural engineering.
BdS: It depends on what model of "space" you want to use, I guess. For example, in the theory of relativity there are spatial and time coordinates (which transform from one reference frame to the next). Then there are various tensors (e.g. the curvature tensor) and other quantities (e.g. the spacetime metric) that describe how the coordinates interact and transform, as well as how distances and time intervals are to be measured using the coordinates. I guess that, if you like, you could call all of these things "properties of space". I'm not sure if I would. The spacetime manifold is curving. Curvature describes a set of mathematical relationships in the model, essentially. Are you being sarcastic? Where have I claimed that I already know everything? There are lots of things I don't know. It is not true that nobody understands the general theory of relativity. However, a more than superficial understanding of it requires quite a high level of mathematics as a prerequisite. Most people do not have the mathematical background required to understand the mathematics of the theory. But some do. I'll give you a simpler example, as an analogy. Consider a curve in two dimensions. We can represent that curve on an x-y plot as a function $y=f(x)$. Without showing you how it is derived, I can tell you that the curvature at any point on such a curve is given by the following mathematical formula: \(C=\frac{|f''(x)|}{[1+(f'(x))^2]^{3/2}}\) where $f'(x)$ is the first derivative of the function and $f''(x)$ is the second derivative. This looks complicated, but I'll give you a specific example or two. Consider the line $y=f(x)=2$. Clearly, on an x-y graph, that is just a straight line. Applying the formula above, we have $f'(x)=f''(x)=0$, and so we easily see that $C=0$. Our line has zero curvature. Next, consider a slightly more complicated straight line: $y=f(x)=7x$. For that line we have $f'(x)=7, f''(x)=0$. Plugging into the formula for the curvature, we again see that $C=0$, as expected. How about a parabola, then? Consider $y=f(x)=x^2$. The derivatives in that case are $f'(x)=2x, f''(x)=2$. So, for the parabola, the curvature is: \(C=\frac{2}{[1+4x^2]^{3/2}}\) Notice that the curvature is no longer a constant; rather, it varies depending on where you are on the curve. For instance, at $x=0$ (the apex of the parabola), the curvature is $C=2$. The magnitude of C, 2 in this case, is a measure of how "curvy" it is at that point. If we pick a point a little to the right, at $x=1$ and calculate we find: \(C=\frac{2}{5^{3/2}}=0.18\) At $x=1$ the parabola is not as tightly curved, compared to $x=0$. If we look at the general curvature formula, we can see that our parabola becomes less and less "curvy" as $x\rightarrow \infty$. So, you get the idea that this measure, C, quantifies our common-sense notion of how curved a line is. In general relativity, things are more complicated. We're dealing with curvature in four dimensions (curvature of a spacetime manifold), and the spacetime at a single point can potentially curve in different directions by different amounts. Of course, all of this is just maths. The power of general relativity is that it tells us why spacetime curves. Matter and energy cause the curvature, and we can quantify exactly how much and what kind of curvature a given amount of mass, say, will cause. GR also allows us to calculate how objects will move in the curved spacetime (under the influence of gravity). ?? What am I doing with you now?
The one where space distance dilates/contracts causing our measurement of time to dilate, and creating a "curve transition" with a variable radial space distance dilation/contraction.
And how the variable radial space distance dilation/contraction ("VSDDC") from the distance of a mass object m1, causes a physical attraction potential for other mass m2 m3... objects located in m1 influenced space. It can be modeled as a curve...
