Why is the fabric of space bendable but also not visible by eye.

607 views

I was looking at how our solar system works and see that essentially the curvature from space and gravity or, lack of creates the movement of our planetary systems. I couldn’t seem to make sense of the details of how space is similar to a fabric and can be shaped in some way.

The example used was the age old blanket with a bowling ball in the center creating a wide curvature leading to the edges of the blanket.

How is this possible but can’t be seen, nor does it cause friction?

I think what happens is that our brains want us to see things as we expect them to be, flat and static in the way we assume the universe operates. It’s like natives of New Guinea calling airplanes “birds”. The mind turns one thing into another in order to understand it. So we do see curved space, but we understand it only by seeing it the way we already understand things. A planet moving back and forth must actually be moving forward, then backward, which of course cannot happen, but there it is up there right in front of our eyes.
