The 1940s theory predicts a linear relationship between the force and the amount of stretching.
Rubber sheet theory.
The rubber sheet analogy of gravity might go back to results in andrei sakharov vacvuum fluctuations in curved space and the theory of gravitation doklady akad.
Picture a flat rubber sheet space time suspended above the ground.
At its simplest spacetime can be thought of as a giant rubber sheet with a bowling ball in the centre.
Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and.
This can be repeated many times with no apparent degradation to the rubber.
Deriving from einstein s notion of spacetime curvature a k a.
The theory assumes that as the rubber is stretched each crosslink remains stationary stuck to its local chunk of rubber even as the chains between crosslinks jiggle around.
The balls on the rubber sheet bend the sheet around them somewhat as matter bends space time in its vicinity.
In the same way the ball would warp the sheet a planet bends the fabric of spacetime.
Topology branch of mathematics sometimes referred to as rubber sheet geometry in which two objects are considered equivalent if they can be continuously deformed into one another through such motions in space as bending twisting stretching and shrinking while disallowing tearing apart or gluing together parts.
It can be stretched by up to a factor of 10 from its original length and when released returns very nearly to its original length.
Rubber elasticity refers to a property of crosslinked rubber.
The jiggling is driven by heat the usual driver of molecular motion.
This concept can be pictured by imagining space time as a rubber sheet.
Einstein s general theory of relativity explains gravity as the curvature of space time.
The main topics of interest in topology are the properties that remain.
The rubber sheet theory but that s just me one reason people struggle with the idea of prayer is that it sounds suspiciously like a fairy granting gifts.
This incident helped me with what i call the rubber sheet theory of prayer.
Mostly these have to do with the fact that it allows us to visualize the spatial aspect of einstein s theory but not the temporal one.
While intuitively appealing however the rubber sheet picture has its limitations.
