China built a moon on the earth. An artificial moon.
In the Eastern Jiangsu area, there is a search facility where they used powerful magnetic fields to weaken Earth’s gravity.
Specifically, the gravity on the moon is 1/6th of that on Earth. So, they used the influence of magnetic fields so that the gravity in the research facility can be brought down to 1/6th.
Apart from this, in this chamber/room they used the same kind of dust and the same kind of rocks like the ones on the moon. So that the entire environment on the artificial moon could be the same as the moon.
According to the researchers, they drew inspiration from a physics experiment from the year 2000. Andre, a physicist from the University of Manchester, made a frog float using magnetic fields.
The artificial moon is now can be used to train the astronauts and the new rovers sent to the moon by the scientists.
