Encouraging discovery is the observation of huge jets that are coming out of central supermassive black holes of several galaxies and are thrown into intergalactic space. These jets represent the new fresh energy for the development of new stars and new galaxies. The origin of the jets is not clear yet, but a group of physicists have a novel idea, namely, that in supermassive black holes of galaxies old matter is transforming back into fresh energy. In supermassive black holes atoms become unstable, they fall apart into elementary particles that form huge astrophysical jets. Supermassive black holes are rejuvenating systems of the universe, they “eat” themselves and transform their old matter into fresh energy. The process of transformation of old matter into fresh energy is keeping the universe “eternally young”. In other words, the entropy of the universe is stable, and central black holes are decreasing universe entropy. The sum of the universe as a whole is constant.
