Warp drive is a legitimate subject of scientific investigation based on general relativity.
Multiple studies demonstrate that warp drive is actively investigated as a legitimate theoretical concept within general relativity, even though significant physical and energetic obstacles remain.
The retrieved literature contains multiple physics papers examining warp drive metrics, energy conditions, and faster-than-light travel proposals specifically through the lens of general relativity. While some papers debate technical feasibility or practical limitations (such as the need for extreme energy conditions), they all treat general relativity as the valid mathematical framework for investigating the subject.
