Wait, isn't the force "that would tear it apart" the same as the gravity you wanted to generate?

An O’Neil Cylinder is a few miles wide. Stainless steel can handle the rotation required to create earth like gravity. If we can practically produce graphemes instead you can go up to several thousand miles in diameter (McKendree Cylinders). 1 AU in diameter is something else entirely.

We can already practically produce graphemes -- just not graphenes. :-)
