Black holes on your desk? Yes it's real

Two Chinese scientists have successfully made an artificial black hole. Technically, such a hole does not require a highly concentrated gravitational field that absorbs light, as Albert Einstein claimed.


The black hole is made of 60 concentric layers of printed circuit board. Each layer is coated with copper and printed patterns that alternately vibrate or do not vibrate in response to electromagnetic waves.
Together, the patterns completely absorb electromagnetic radiation coming from any direction, and their energy is converted into heat.

UPD: in order to avoid unnecessary traffic in the comments, I will immediately make a reservation - black holes, unlike completely black bodies, bend the rays of light, as can be seen in the second figure (image A).
