Rather, their size (more precisely their Schwarzschild radius) increases proportionally to their mass, so they grow as they accrete more matter. It is a common misconception that everything expands along with the expanding Universe. It doesn't. dvc magic resales reviews

"Web2. Mass still falls into a black hole, it's just that from the point of view of the mass, its last instant outside of the hole is infinitely long. The mass falls into the hole, but just can't perceive that it has. We detect black holes because they emit x-rays, have accretion discs, and have a very strong gravitational field.
