In physical reality there are no black holes. Instead there are intense magnetic field regions that are formed whenever the field strength in plasma becomes much stronger compared with its surroundings. The most intense magnetic field regions are formed at the most dense regions of the Universe. These super-intense magnetic field regions are characterized by the formation of gaps -or more precisely circular gaps- that rotate at some regions with superluminal velocity. In other words, these circular gaps are open field lines formed in the most active regions on the surface of a dense plasma environment. It is a phenomenon structured and ruled by magnetism. It is similar to the formation of sunspots and coronal holes. Sunspots are magnetic phenomena as well. They are regions of very strong magnetic fields where the field lines get so crowded together that they push up through the surface, bringing some of the hot plasma with them in a spectacular arc, or loop. Basically, the strong magnetic field, not allowing motions across the field lines, quenches convection inside the spot. They are darker than the surrounding areas because they are expending less energy and as a result have a lower temperature. The spots formed on the surface of the Sun have also been seen on other stars.
