A rotating black hole is such an extreme force of nature that it drags surrounding time and space around with it. So it is only natural to ask whether black holes could be used as some sort of energy source. In 1969, mathematical physicist Roger Penrose proposed a method to do just this, now known as the “Penrose Process.” The method could be used by sophisticated civilizations (aliens or future humans) to harvest energy by making “black hole bombs.” Some of the physics required to do so, however, had never been experimentally verified — until now. Our study confirming the … Read more

Power and Energy

by
Future Energy

Today’s topic comes via QSFer Belinda McBride: “Power and energy. How are your communities powered? Is it clean power? Fossil fuel? What runs your transportation?” Going forward as the world warms up, the type of energy we use will become more and more inportant. But beyond that, we’ll need different forms of energy and engines if we’re going to cross the solar system more efficiently, or even cross the gulfs between the stars. So get out your crystal ball today and share your predictions for the future of energy. And share, also, some of your favorite books that have dealt … Read more
