    Black hole Hole
AI Thread Summary
Two Chinese scientists have developed an artificial black hole capable of trapping microwaves at its center, allowing energy to flow in one direction. This setup raises questions about the behavior of two black materials emitting electromagnetic waves, one inside the black hole and one outside. The inner material cannot emit microwaves outside but absorbs those from the outer material, potentially increasing its temperature. This scenario suggests a violation of entropy, resembling a perpetual motion machine of the second kind. The discussion highlights the implications of this experiment on our understanding of thermodynamics and entropy.

Two chinese scientist have created an artificial black hole that can trap the microwave into the center of this called -- black hole --.
It sames that in this machine the energy of microwave could travel only in one direction, from outside to the center.
If this is true is wonderful...
Imagine that we have an insulated system where there are only the black hole and two black materials that emit E.M wave (and then microwave too); one black material is inside the black hole and a black material is outside... what will happen? It sames that the black material in the center of black hole can't emit microwave outside the black hole, but in the same time will absorb the microwaves emitted by the other black material and then the inside black material will became hotter...
It sames a violation of entropy, a perpetual motion of second kind machine.

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
