Webb18 apr. 2015 · The rubber sheet analogy is only a visual representation of gravitation outside a massive body. As gravity is proportional to mass, not size, the analogy becomes awkward if applied to a large hollow object. A hollow object affects the objects outside it as though all its mass were concentrated at a point in its center. Webb17 feb. 2009 · The problem I have with the rubber sheet analogy is that it appears to be more appropriate for the Newtonian theory of gravity. I’ve used it that way. The depth that a single bowling ball sinks is proportional to its Newtonian gravitational force. The changing depth of the sheet around the ball demonstrates the force field gradient perfectly.

Webb16 nov. 2024 · Since spacetime warping can be a difﬁcult concept to understand and visualise, an analogy is often used in physics education: spacetime can be thought as a thin rubber sheet. The way masses warp the rubber sheet and affect other smaller masses can help students develop an intuitive understanding of how gravity works under GR.

WebbI think you have to take it as in real life things naturally go in a straight line, but in the analogy of the rubber sheet the natural path is to follow the rubber sheet. The same way if you look at a straight line through a non uniform piece of glass the line doesn't look straight but it still is. – Jonathan.

The problem is the rubber sheet is a 2D surface. It can represent two dimensions. It can be two of space (as is normal), one space and one time, etc. Real spacetime is a 4D entity - 3 (elongated) space, 1 time. kingston wall clockWebbThis work is licensed under a Creative Commons Attribution-NonCommercial 2.5 License.
