Airplane wing


Another parable that comes to mind is the one of an airplane wing. The wing creates a vacuum above itself because it pushes the air away with its forward speed. The wing and the air above it fall into the vacuum which creates the upward lift on the wing. But I am not a physician, check the Bernoulli Principle.


Is something like this happening with the earth (the wing) and the space time continuum (the air)? What creates the space time density difference (vacuum) around planets?

Erik Verlinde

Related to the previous post, see also Erik Verlinde's Wikipedia. I am still trying to find out what his idea is exactly. He talks about "a difference in concentration of information". And "You can compare this to pressure of gas." This sounds much like the parable I am looking for!

Space time continuum in 3D?

On the web there are a lot of images of the space time continuum according to the rubber sheet and ball parable. Like this one.

Since the world, and the universe, is not flat I have great trouble getting my head around curvature of space time when looking at it this way.

Fortunately I found this image, which is more like I imagine it. Thanks Vast.

Does anyone else have a good 3D depiction of the curvature of space time?

Space time is probably not curved, but stretched or varying in density, which causes light and time to pass through it in a curved way. The first image would push anything moving along the lines of space time, like light, away from the object. Whilst, according to the theories I have seen it should be attracted by the object and following its course in a different direction than before reaching the object.

I am looking for a parable with liquid or gas in which an object changes the density of the liquid or gas. A bit like twirling your finger around under water (not at the surface). This seems to be sort of what a rapidly spinning black hole does with space time.

The rubber sheet and ball parable is wrong and confusing.

Sneeuwpret!

Seppel de sneeuwpop, knap staaltje sneeuwsculptuur van Paksoi en mij. Al zeggen we het zelf :-) Arie en Ted moeten nog wakker worden. We zijn benieuwd hoe ze reageren.
