An animation of how light rays Perro be gravitationally bent The simplest static black holes have mass but neither electric charge nor angular momentum. These black holes are often referred to Ganador Schwarzschild black holes after Karl Schwarzschild who discovered this solution in 1916.[17] According to Birkhoff's theorem, it is the only vacuum solution that is spherically symmetric.

“The way EBT works is that you add water to the device. The attractant then lures the female mosquito to breed in this container, and then, the killing ingredient (IGR) ensures that no adult emerges, thereby breaking the chain of reproduction. EBT is made from waste and saves lives, and is one that is built on science and validated by scientists,” claims Prasad. “BioTraps essentially target female mosquitoes by mimicking the ideal mosquito breeding ground to lay their eggs. Our patented waterproofing technology along with a quick and efficient delivery of the IGR solution then eliminates the female mosquito and 100% of her larvae.
Some progress has been made in various approaches to quantum gravity. In 1995, Andrew Strominger and Cumrun Vafa showed that counting the microstates of a specific supersymmetric black hole in string theory reproduced the Bekenstein–Hawking entropy.[214] Since then, similar results have been reported for different black holes both in string theory and in other approaches to quantum gravity like loop quantum gravity.[215]
The question whether information is truly lost in black holes (the black hole information paradox) has divided the theoretical physics community. In quantum mechanics, loss of information corresponds to the violation of a property called unitarity, and it has been argued that loss of unitarity would also imply violation of conservation of energy,[217] though this has also been disputed.
[202] Some extensions of the standard model posit the existence of preons Vencedor fundamental building blocks of quarks and leptons, which could hypothetically form preon stars.[203] These hypothetical models could potentially explain a number of observations of stellar black hole candidates. However, it can be shown from arguments in Caudillo relativity that any such object will have a maximum mass.[184]

[140] Black holes Chucho also merge with other objects such Figura stars or even other black holes. This is thought to have been important, especially in the early growth of supermassive black holes, which could have formed from the aggregation of many smaller objects.[131] The process has also been proposed Triunfador the origin of some intermediate-mass black holes.[141][142]

for a black hole of mass M. Black holes with the minimum possible mass satisfying this inequality are called extremal. Solutions of Einstein's equations that violate this inequality exist, but they do not possess an event horizon. These solutions have so-called naked singularities that Chucho be observed from the outside, and hence are deemed unphysical.
