Well, though I do believe the laws of physics do apply and can't be switched off by higher technology, it is not unimaginable still there's indeed some kind of warpdrive-like device.
But that they would leave no trace somewhere around the planet that at least would deeply baffle us, that gets harder to imagine. The deeply scientific show called star trek taught me that even the klingon's cloaking device leaves back traces.
