explain gravity with 3d picture

?using gravity to explain gravity?

Show me a 3d picture. DO you perhapos mean a sculpture?

Besides, gravity is 4d, you can't "explain" it in 3d any more than you can "explain" a cube in 2d.

What is "analogy?" What is "perspective?"

They are rolling marbles around the weight of the "Earth" in the center, to demonstrate by analogy how the mass of the objects on the sheet distort the 2-d space in a manner similar to that in which the mass of the Earth distorts 3-d space. The marbles are small and maybe you did not notice them.

this demonstration is explaining how gravity works in a 2D universe. The distortions are only visible in 3d, so if you were living in flatland the gravity distortion wouldn't be visible. Wouldn't this mean that gravity in our 3d universe, has visible distortions in 4d? That would mean our universe is actually 4d and not 3d.

There's a theory out there that suggests black holes are really 2D space that project a hologram on 3d space. Perhaps our universe is a black hole in 4d space.

You can explain a cube in 2d, you can show it to 2d people, but they will never understand it fully without having seen the third dimension. To them, it is a collection of overlapping, connected shapes.
Just like a 3d representation of a tesseract looks like overlapping, connected forms.

This demonstration is extremely common. Do you live under a rock?
