“Halo Drive” could reach relativistic speeds by firing light around a black hole

by

If we want to one day explore the galaxy (let alone the rest of the universe), we have a speed problem. In late 2023, NASA’s Parker Solar Probe reached the fastest speed ever achieved by a man-made object, clocking in at 635,266 kilometers (394,736 miles) per hour. While impressive, that’s only 0.059 percent of the … Read more
