do black holes grow
After a black hole has formed, it can continue to grow by absorbing mass from its surroundings. By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses (Mâ) may form. There is general consensus that supermassive black holes exist in the centers of most galaxies.fter a black hole has formed, it can continue to grow by absorbing mass from its surroundings.
