Abstract Critical gravity is a quadratic curvature gravity in four dimensions which is ghost-free around the AdS background. Constructing a Vaidya-type exact solution. we show that the area of a black hole defined by a future outer trapping horizon can shrink by injecting a charged null fluid with positive energy density. so that a black hole is no more a one-way membrane even under t... https://jalyttlers.shop/product-category/fryer/
