Gravity Rubber Sheet Analogy

The rubber sheet analogy for einstein s general relativity model of gravity is a popular way to visualize the effect mass has on the curvature of spacetime.

Gravity rubber sheet analogy.

Since i read cosmos long ago i see the same analogy about the balls rolling on a rubber sheet used to explain how gravity works. My single group quasi experimental study with repeated measures was designed to assess the effectiveness of the rubber sheet analogy in teaching gravitational fields. The rubber sheet analogy for einstein s general relativity model of gravity is a popular way to visualize the effect mass has on the curvature of spacetime. This state of affairs is almost entirely the result of one the most famous analogies in science.

That the warping of spacetime to produce gravity is like the deformation of a rubber sheet by a central mass. But a ball rolls on a surface because gravity is pulling it down. In space it will follow a straight line and go over any hole on the surface. Experiments reveal that deformed rubber sheet is not like spacetime.

The rubber sheet or trampoline analogy for gravity is flawed because it is not fully three dimensional as a real star and planets would be. Now physicists have tested this idea theoretically and experimentally and say it doesn t hold water.
