It is believed that the formation and growth of most galaxies across the history of the universe has been fueled by supermassive black holes growing together with their host galaxy as they collect matter to attain millions of solar masses.  Astronomers at Radboud University in the Netherlands have recently shared their plans to work with the European Space Agency (ESA) and others to get a better look at black holes by placing two to three satellites in a circular orbit around Earth.  Astronomers on Wednesday unveiled the first photo of a black hole, one of the star-devouring monsters scattered throughout the Universe and obscured by impenetrable shields of gravity.  Paul McNamara, an astrophysicist at the European Space Agency and project scientist for the LISA mission that will track massive black hole mergers from space, helped AFP put what he called an "outstanding technical achievement" into context.  We're about to see the first close-up of a black hole.  In short, the concept of a black hole gravity machine presents humanity with a plausible path to becoming an interstellar species. In the meantime, the study of the concept will provide SETI researchers with another possible technosignature to look for.  Physicists have used a seven-qubit quantum computer to simulate the scrambling of information inside a black hole, heralding a future in which entangled quantum bits might be used to probe the mysterious interiors of these bizarre objects.  Rotating black holes and computers that use quantum-mechanical phenomena to process information are topics that have fascinated science lovers for decades, but even the most innovative thinkers rarely put them together.  If someone were to venture into one of these relatively benign black holes, they could survive, but their past would be obliterated and they could have an infinite number of possible futures.  The group explains their theory in a paper published in the journal Physical Review Letters-it involves the idea of primordial black holes (PBHs) infesting the centers of neutron stars and eating them from the inside out.
