American scientists even came up with a project: to use a large meteorite crater as a radio telescope dish by covering it with wires — essentially creating a reflective surface and turning it into a natural radio telescope. This would require such enormous costs and effort that, for now, the project is considered something for the distant future. But Chinese astronomers have decided to do it now — within the next 7 to 10 years. They’re talking about five years. I looked at the scale of the project and realized that it’s unlikely to be completed in less than 10 years
