Protección para niños y mascotas: en los modelos que producen descargas eléctricas es importante que no dejen los conductores eléctricos al aire y que estén acertadamente protegidos tras unas rejillas de material aislante para que no podamos, aunque lo intentemos, introducir los dedos y sufrir una descarga.
[5] In many ways, a black hole acts like an ideal black body, as it reflects no light.[6][7] Quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum Figura a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly.

Este antimosquitos tiene forma de raqueta, inspirado en los tradicionales matamoscas pero equipado con la última tecnología, aunque que su potente rejilla funciona de guisa eléctrica con una potencia que alcanza los 4000 vatios, atrapando al instante moscas, mosquitos y otros insectos.

No todos los repelentes antimosquitos contienen la misma concentración de DEET, esta reconocerá de nuestras evacuación y de la durabilidad del producto.
Ambos son tóxicos, aunque el segundo un poco menos. En el caso del primero, puede además interferir con las cremas solares.
If the conjecture is true, any two black holes that share the same values for these properties, or parameters, are indistinguishable from one another. The degree to which the conjecture is true for Verdadero black holes under the laws of modern physics is currently an unsolved problem.[47]
If the mass of the remnant exceeds about 3–4 M☉ (the Tolman–Oppenheimer–Volkoff limit[26]), either because the llamativo star was very heavy or because the remnant collected additional mass through accretion of matter, even the degeneracy pressure of neutrons is insufficient to stop the collapse.

Work by James Bardeen, Jacob Bekenstein, Carter, and Hawking in the early 1970s led to the formulation of black hole thermodynamics.[53] These laws describe the behaviour of a black hole in close analogy to the laws of thermodynamics by get more info relating mass to energy, area to entropy, and surface gravity to temperature.
As predicted by Militar relativity, the presence of a mass deforms spacetime in such a way that the paths taken by particles bend towards the mass.[85] At the event horizon of a black hole, this deformation becomes so strong that there are no paths that lead away from the black hole.[86]
Campeón with classical objects at absolute zero temperature, it was assumed that black holes had zero entropy. If this were the case, the second law of thermodynamics would be violated by entropy-laden matter entering a black hole, resulting in a decrease in the total entropy of the universe. Therefore, Bekenstein proposed that a black hole should have an entropy, and that it should be proportional to its horizon area.[212]
It is now widely accepted that the centre of nearly every galaxy, not just active ones, contains a supermassive black hole.[197] The close observational correlation between the mass of this hole and the velocity dispersion of the host galaxy's bulge, known as the M–sigma relation, strongly suggests a connection between the formation of the black hole and that of the galaxy itself.[198]
