La simulation de trou noir ressemblait fortement au vortex qui se forme lors du retrait du bouchon dans un bain

Des scientifiques de l’Université de Nottingham ont révélé de nouvelles connaissances sur le comportement des trous noirs via une simulation de l’un des géants de l’espace dans un réservoir d’eau

Le nouvel article de l’équipe de recherche, publié dans Physical Review Letters, détaille comment ils ont simulé un phénomène appelé réaction inverse

Doing this, la leur est la première étude à démontrer comment l’évolution des trous noirs, en fonction de leurs champs environnants, peut être simulée en laboratoire

The researchers used a reservoir simulator made of a draining vortex to mimic a black hole The same way water flows when you empty a bath, any wave that gets too close to the drain is inevitably drawn into the plughole

Using this technique, researchers have shown that when waves are sent into an analog black hole, black hole properties can change drastically

The reason is surprisingly simple: when the waves approach the drain, they effectively push more water into the plughole, which decreases the total amount of water contained in the tank.

This results in a change in water level, which corresponds to a change in the properties of the black hole, according to the observable rules of the researchers' simulation

“For a long time, it was not known whether the reverse reaction would result in measurable changes in analog systems where fluid flow is driven, for example using a water pump We have shown that analog black holes, like their gravitational counterparts, are inherently reverse reaction systems, »lead author Dr Sam Patrick, from the School of Mathematical Sciences at the University of Nottingham, explains in a press release

Nous avons montré que les vagues se déplaçant dans une baignoire drainante poussent l’eau dans le trou du bouchon, modifiant de manière significative la vitesse de vidange et par conséquent, la force gravitationnelle effective du trou noir analogique”, he continues

Les chercheurs disent que leurs découvertes seront essentielles pour les futures expériences Par exemple, ce type d’interaction seracrucial pour étudier l’évaporation des trous noirs en laboratoire”, le Dr Patrick explique

L’Université de Nottingham a récemment reçu 4 £3 millions (5 $8 millions) de financement pour la recherche sur les trous noirs: l’équipe de recherche vise à utiliser des simulateurs quantiques pour imiter les conditions de l’univers primitif et, ce faisant, découvrir les mystères du cosmos
