It is said that a black body emits a type of thermal radiation that can both repel and attract nearby objects, such as atoms and molecules. For objects that are not so massive and hot enough, this black body radiation may even be stronger than their gravitational pull. Both the black Body radiation (repel) and the force of the Black Body (attract) produce an interaction of forces that is often explored in the field of quantum optics. The new study of Brazil, published in the magazine Europhysics Letters, explores as the shape of a black body, as well as its effect on the curvature of the surrounding space-time, influences this attraction and optical repulsion. To show this, the researchers calculated the topology, or the deformation of space, around black spherical and cylindrical bodies, measuring how the black-body radiation forces of each object are affected. They found that the curvature of the space around the spherical black bodies amplifies the attractive force. Meanwhile, this magnification has not been detected in cylindrical black bodies.
Planets and stars
So how does that affect what we know about the interaction between cosmic bodies? Although this effect is not exactly detectable in a laboratory or even in objects as large as the sun, researchers believe that this makes a considerable difference when it comes to massive black bodies. The main researcher, Phys.org, said to the:
We think that intensifying the strength of the black body due to ultradensas sources can detect the phenomena associated with them, such as the emission of very energetic particles, and the formation of accretion disks around black holes, "
Researchers believe that this new understanding of the black body's strength and radiation can help refine the way we model the formation of planets and stars. It could even help us figure out a specific type of black body force known as Hawking radiation, which would allow the evaporation of black holes.
