Dark Matters

“In August, physicist Jia Liu at New York University outlined his design for a spacecraft powered by dark matter. Soon afterwards, mathematicians Louis Crane and Shawn Westmoreland at Kansas State University in Manhattan proposed plans for a craft powered by an artificial black hole. No one disputes that building a ship powered by black holes or dark matter would be a formidable task. Yet remarkably there seems to be nothing in our present understanding of physics to prevent us from making either of them. What’s more, Crane believes that feasibility studies like his touch on questions in cosmology that other research hasn’t considered.”
