  • A laser-driven tidal wave could test a question that has long baffled physicists: is information inside a black hole lost forever or somehow preserved through the mysterious machinations of quantum mechanics? The defining feature of a black hole is thought to be that anything that crosses the event horizon -- the proverbial point of no return -- can never escape and is lost forever. Unfortunately, there's no good way to study a black hole up close to test what's really going on. So physicists have been exploring "analogue" black holes that mathematically mimic their celestial counterparts. Researchers have suggested that an accelerated minor could mimic a black hole's event horizon, providing a way to look for these correlations in the lab.
