Scientists have not found additional collapsed measurements

Scientists from the University of Washington did not find additional collapsed dimensions in the universe. To do this, they measured gravity at a distance of less than 50 microns.

Researchers have suggested that the universe has many collapsed dimensions, but they are hidden from direct experiments by scientists. In their opinion, measurements can be compact and manifest themselves only on extremely small scales, can be weak, so they are difficult to detect.

In order to measure the attraction between them, scientists used a fast disk that is affected by changing gravity. It was also created by a disk that rotates on the same plane.

Special grooves were applied to them – during rotation they constantly coincided with each other, but at different distances. If the gravity changed, this was fixed by a special detector.

This experiment accurately recorded gravity at a distance of less than 50 microns, the researchers did not find signs of collapsed measurements. However, physicists plan to continue to search for them – with the help of more microscopic experiments and accurate observations.
