Gravity Rubber Sheet Analogy

One of the most famous analogies in science is fundamentally flawed say physicists who have shown that a.

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. 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. Now physicists have tested this idea theoretically and experimentally and say it doesn t hold water. 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 or trampoline analogy for gravity is flawed because it is not fully three dimensional as a real star and planets would be. That the warping of spacetime to produce gravity is like the deformation of a rubber sheet by a central mass. Experiments reveal that deformed rubber sheet is not like spacetime. In space it will follow a straight line and go over any hole on the surface.
