Sending Signals Back in Time Near Black Holes

Scientists are exploring how spinning black holes might warp spacetime enough to allow signals to travel backward in time—no DeLoreans needed. Based on Einstein’s relativity, these black holes could create “closed timelike curves” around their ring-shaped centers. Inspired by Interstellar, researchers found that future senders, armed with knowledge of the past, could actually improve message accuracy by correcting noise or sending multiple copies. This doesn’t mean changing history—physics keeps things self-consistent—but could revolutionize quantum computing and our understanding of time.
