​​How much energy would it take to travel through time?

Time travel has always fascinated mankind, but a Star Trek kind of warp drive has till now been impossible to build. This hasn’t discouraged scientists to continue researching it.
Scientists have long debated the practicality of warp drive—or traveling faster than the speed of light. While some argue that the entire concept defies the laws of physics as we know it, others continue to press on in their effort to prove that warp drive could one day be a reality, sparking an era in which we would finally become a true space-voyaging species.
