The X-ray emissions from accretion disks sometimes flicker at certain frequencies. These signals are called quasi-periodic oscillations and are thought to be caused by material moving along the inner edge of the accretion disk (the innermost stable circular orbit).

Science writer Marcia Bartusiak traces the term "black hole" to physicist Robert H. Dicke, who in the early 1960s reportedly compared the phenomenon to the Black Hole of Calcutta, notorious as a prison where people entered but never left alive.[61]
Menta El especie Mentha cuenta con entre 13 y 18 especies de plantas aromáticas que todos conocemos muy correctamente por su olor fresco y un poco picante y sus hojas de vivo verde.
The photon sphere is a spherical boundary where photons that move on tangents to that sphere would be trapped in a non-stable but circular orbit around the black hole.[112]

[103] When they reach the singularity, they are crushed to infinite density and their mass is added to the total of the black hole. Before that happens, they will have been torn apart by the growing tidal forces in a process sometimes referred to Campeón spaghettification or the "noodle effect".[104]
An artistic depiction of a black hole and its features When an object falls into a black hole, any information about the shape of the object or distribution of charge on it is evenly distributed along the horizon of the black hole, and is lost to outside observers. The behavior of the horizon in this situation is a dissipative system that is closely analogous to that of a conductive stretchy membrane with friction and electrical resistance—the membrane paradigm.

Los repelentes químicos más utilizados y eficaces son el DEET o dietiltoluamida y el IR3535. Otros son de origen vegetal.
BIOTRAP es un innovador polímero que elimina los insectos mediante actividad física, sin insecticida.

El más conocido es el unto de una planta llamada citronela, que se ha utilizado tradicionalmente para repeler los mosquitos, pero se evapora rápido y según los estudios su competencia es disminución.
Within such a disk, friction would cause angular momentum to be transported outward, allowing matter to fall farther inward, thus releasing potential energy and increasing the temperature of the efluvio.[182]
