I have been following these developments. We know so little about Black Holes, it's difficult to comprehend the power they have. I have watched science shows that tried their best to describe what science knows.It has been suggested that there are such things as roving Black holes as well. The other incredibly destructive force is a magnetar
Quote: The density of the interior of a magnetar is such that a tablespoon of its substance would have a mass of over 100 million tons. Magnetars are differentiated from other neutron stars by having even stronger magnetic fields, and by rotating comparatively quicker. Most neutron stars rotate once every one to ten seconds, whereas magnetars rotate once in less than one second. A magnetar's magnetic field gives rise to very strong and characteristic bursts of X-rays and gamma rays.
