If you follow the news about the physics of the universe, then for sure at least once, but you have come across the term "the power of the absolute black body." In 2013, a group of scientists announced the discovery of the existence of an unusual force that could potentially be more powerful than gravity. And now researchers from the State University of Brazil and the Federal University of Brazil have shared new details about this strange phenomenon.
The term "absolute black body" was first introduced by physicist Gustav Kirchhoff in 1862. Absolute black bodies are a class of objects that at any temperature absorb all the electromagnetic radiation incident on them in all ranges, but they can emit their electromagnetic radiation of any frequency. Despite the name, absolute black bodies have color. One example is neutron stars.
It is believed that absolute black bodies are able to release a special type of thermal radiation, the so-called "black-body radiation," which simultaneously can attract and repel neighboring objects, affecting the internal energy of the same atoms and other particles. This influence is just called "the power of the absolute black body." Scientists are primarily interested in how objects belonging to the class of absolute black bodies and not always possessing high mass and temperature indicators are capable of producing radiation whose force of impact can be stronger even by the force of attraction. The interaction of the radiation of the absolute body (repulsion) and the force of the absolute black body (attraction) often becomes the object of investigation of the sphere of quantum optics.
In a new study by Brazilian scientists whose results were published in the scientific journal Europhysics Letters, experts wonder how exotic astronomical bodies (belonging to the class of absolute black bodies), as well as deformation of the surrounding space, can influence the power of the absolute black body. In their work, scientists calculated the topology, or the deformation of the space surrounding both spherical and cylindrical absolute black bodies, and found out how the affecting radiation force of each of them changes. Researchers have established that the curvature of space around spherical objects enhances the force of attraction. At the same time, such changes will not be observed in absolute black bodies of cylindrical shape.
What does this have to do with the principles of the interaction of cosmic bodies? This effect has not yet been determined directly in the laboratory, or even near objects that have a mass of the Sun, but scientists are sure that the situation will be completely different if we are talking about supermassive absolute black bodies.
"We think that the force of absolute black bodies, present in the conditions of deformation of space around objects that can be attributed to a class of absolutely black bodies and possessing an ultrahigh density, is capable of exerting a more significant influence on surrounding objects than gravitational attraction of objects within an undeformed space. For example, the same high-charged particles that form accretion disks of black holes, "says lead researcher Celio Muniz.
According to scientists, understanding the force of the impact of absolute black bodies and their radiation will help us in developing more accurate models for the formation of planets and stars. And in the future, and to detect a special force, the so-called Hawking radiation, according to which black holes are able to emit elementary particles.
"This work allows us to consider the discovery made in 2013 in a broader context," concludes Muniz.
