String theory brings a new model for the matter.

Black holes and the Schwinger effect are the ultimate combinations. When we are thinking about the Schwinger effect, where strong electromagnetic fields are turning into material or elementary particles. 

While black holes pull radiation inside them, that radiation crosses extremely thick and powerful radiation areas. In that radiation area, incoming radiation impacts radiation or wave motion that orbits the black hole's event horizon. 

When those radiation or wave motion whirls are crossing. That causes the Schwinger effect. When the Schwinger effect makes particles. It creates particles and their antiparticle pair. The Schwinger effect is possible in all radiation fields. Including gravitational waves and fields. 

The gravitational fields around black holes are very powerful. And Schwinger effect in crossing gravitational fields should form the elementary particles. That is unknown to science. Also, very powerful gravitational fields can interact with other radiation types like gamma- and X-rays. And in that case, is also forming particle-antiparticle pairs. 

So are dark matter and dark energy the result of the Swinger effect around black holes? In those kinds of cases, the Schwinger effect forms pair of elementary particles. And there is a possibility that the hypothetical graviton and its anti-particle pair can also form near black holes. If those particles and their antiparticle pairs are impacting that thing sends radiation around the universe. 

So maybe dark matter or at least some part of dark matter are particles that are forming near black holes or in crossing electromagnetic fields in the universe. And the dark energy could be a result of the annihilation of those yet-unknown particles. 

String theory is an interesting tool in modern material research. The idea of this theory is the extremely thin energy fields or energy strings or so-called superstrings form the entire material. 

The thing that is called the Schwinger effect proves that crossing wave motions can turn to the material. And otherwise material can turn to wave motion. Scientists knew hundreds of years that material can turn into energy. But the opposite reaction. Where energy or wave motion turns to material or particles is not known for a very long time. 

And that means the material is the form of wave motion or energy. Researchers proved the ability to turn wave motion into particles a couple of years ago. There was an experiment where wave motion turned to elementary particles. That thing opens a new model in theoretical physics. 

There is a possibility that someday researchers can make a quantum propeller that can aim wave motion to the sides. And if there is crossing wave motion in that system. That quantum propeller makes it possible to create synthetic elementary particles and their antiparticles. 

The Schwinger effect means the strong magnetic fields are creating material. And the quantum propellers aim strong cross, pike-shaped magnetic field to the base field. 

The idea is that the Schwinger effect creates elementary particles. That exists only in the laboratory. And that thing makes it possible to create matter. That is invisible to the human eye. So maybe that thing allows the creation of dark matter.
