RE: Spacetime Torsion visualization |
Hi,

having seen myriads of such "Apple on a Pillow" visualisations
of "gravitation" and "spacetime distortion",
I wonder if there is a way to visualize spacetime torsion.

Looks like a rubber sheet with a ball pulled by gravity.
Amazing how gravity is used to describe gravity.

Yeo, and it's wrong anyway.
But when Uncle Al finally announces the torsion result,
all world will come running and yell:
what does it look like?
Hurry up, we must prepare a visualisation :-)

Maybe look at the rubber sheet on the other side and use antigravity?

Those spacetime curvature models are exactly WRONG. Start with a
suspended Euclidean flat rubber membrane under tension. Draw a
regular triangular grid. The three internal angles of any triangle
sum to exactly 180 degrees. Now add your shotput. The membrane
deforms into a "gravitational" well. The triangles' sides curve
inward inward. The sum of their internal angles is now less than 180
degrees.
The gravitational case would have their internal angles sum to more
than 180 degrees.
Spacetime torsion models like a Lorentz force in electromagnetics.
One is reminded of Robert Heinlein's question: What happens if you
push a running gyroscope in three orthogonal directions?
