According to Tech Times, this space behemoth would actually be assembled in orbit, with materials launched into space from Earth. The process of creating materials, sending them into orbit, and attaching them in space would also be covered in the feasibility report, should the five-year process receive funding. The cost of figuring out if such a project is possible would be around $2.3 million.
The limit to this real-life Enterprise is engineering, not science, according to NASA employees questioned about the project. It's not completely insurmountable, with the biggest obstacle being the sheer scale of the ambitious proposal, and the inevitable eye-watering prices required to build and launch the materials needed. The International Space Station, which is a 10th of the size of the Chinese proposal, cost $100 billion to make, so something on this scale will surely bring a hefty bill. However, if the materials were light enough, and the ship was merely long but not necessarily heavy or massive, it could be feasible. One has to wonder what kind of structures we'll have among the stars in the decades and centuries to come.
