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?

Spacetime is bent by gravity. Gravity is really weak compared to the other fundamental forces.
You ever seen one of those spinning levitating magnetic tops? The magnets in the top and in the base, which you can hold in your hand, are able to cancel out the downward pull from *the entire planet and everything on it*. That’s how much stronger electromagnetism is than gravity.
Therefore, the bending effect of spacetime is too small to measure or detect unless you have something incredibly massive (like a black hole). Even with some of the world’s most precise measuring devices, we can barely detect the ripples from crazy violent events like neutron stars merging.
