If you follow the news about the physics of the Universe, then surely at least once, but faced with the term “power absolute black body”. In 2013 a group of scientists announced the discovery of the existence of unusual forces, which potentially can be more powerful than gravity. And now researchers from Searsboro state University of Brazil and Federal University of Brazil has shared new details about this strange phenomenon.
The term “absolute black body” was first introduced by physicist Gustav Kirchhoff in 1862. Absolute black body is a class of objects which at any temperature absorbs all incident electromagnetic radiation in all ranges, but can emit their electromagnetic radiation of any frequency. Despite the name, the absolute black body have colors. One example is a neutron star.
It is believed that the absolute black body can release a special type of thermal radiation, the so-called “ceretelevo radiation”, which can simultaneously attract and repel nearby objects, affecting the internal energy of the atoms and other particles. This impact is just called “power of an absolute black body”. Scientists are primarily interested in how the objects belonging to the class of absolute black bodies, and not always with high weights and temperatures, are able to generate radiation whose power of influence may be even stronger than the force of gravity. The interaction of the radiation of the absolute body (repulsion) forces and the absolute black body (attraction) often becomes the object of research in the field of quantum optics.
In a new study by Brazilian scientists, the results of which were published in the scientific journal Europhysics Letters, experts are wondering about how exotic astronomical bodies (belonging to the class of absolute black bodies), but also deformation of their surroundings can influence the power of an absolute black body. In their work the researchers conducted a calculation of the topology, or deformation of the space surrounding the spherical and cylindrical absolute black body, and found out how this changes impact the strength of radiation of each of them. The researchers found that the curvature of space around a spherical object increases the force of attraction. At the same time, such changes will not be observed in absolute black bodies of cylindrical shape.
What this has to do with the principles of the interaction of space bodies? This effect directly has yet been identified neither in the laboratory nor even close to the objects with mass of the Sun, but scientists are confident that the situation will be quite different, if it would be a supermassive absolute black bodies.
“We think that the power of absolute black bodies present in the conditions of deformation of space around objects, which can be attributed to the class of black bodies and with high density, is able to exert a more significant influence on the surrounding objects than the gravitational attraction of objects inside non-deformable space. For example, the same highly charged particles forming the accretion disks of black holes,” says lead researcher Celio Muniz.
According to scientists, understanding the impact of absolute black bodies and their radiation will help us to develop more precise models of the formation of planets and stars. And in the future and discover a special power, the so-called Hawking radiation, according to which black holes can emit elementary particles.
“This work allows us to consider the discovery made in 2013 in the broader context,” says Muniz.
