What is isospace?

Question

What is isospace?

Answer 1

"In the theory of isospace, all space is curved: not curved in something, but none the less, curved. So if three-space is curved in four-space, then four space is curved in five-space, and so forth. Any practical model of curvature not involving being bent in space must also equate to being bent in space, if room exists.

A model of curvature would be to add or subtract circumference to a circle. A circle drawn on a sphere has a smaller circumference than 2π of its radius. And here lies the secret of curvature.

So instead of having curvature at points, we make point and direction a feature of curvature. In an isospace, at any point, the length of any arc of space around it depends only on the radius and angle.

Consider, now what would happen, if different degrees of the circle around a point are different lengths. The tension of space is not defined by angle but circumfence length. The degrees that have longer lengths would pull harder, and there would be a net force produced by empty space. This is a method for explaining gravity without relying on force at a distance.

The presence of a large body would cause more of space to be bunched in the degrees nearer the body, and this would propegate across space by way of tension of curvature.

A line straight through the point would divide the perimeter, and so we would have a curved line being the inertial line. So, we do not need the tension of space to become a binding force, just twisting the notion of a straight line is enough.

So even something without mass for force to act on, would feel the effect of space bending. The subtle effect of making half the circle longer than the other half would cause a straight line to span less than 180 degrees, and light (which moves in a straight line), to 'bend'.

Such is observed in gravitational lensing, where a distant quasar appears above and below a galaxy."
