Scientists Are Starting to Take Warp Drives Seriously, especially One Specific Concept ( Alcubierre “Warp” Drive). In recent years, the scientific community has become understandably excited and skeptical about claims that a particular concept – the Alcubierre “Warp” Drive – might actually be feasible.
The Alcubierre Drive achieves Faster than Light (FTL) travel by stretching the fabric of space-time in a wave, causing the space ahead of it to contract while the space behind it expands. The theory suggests that the spacecraft inside of the wave would be able to ride this “warp bubble” and achieve velocities beyond the speed of light. This is what is known as the “Alcubierre Metric”.
Interpreted in the context of General Relativity, the interior of this warp bubble would constitute the inertial reference frame for anything inside it. By the same token, such bubbles can appear in a previously flat region of space-time and exceed the speed of light.
Since the ship is not moving through space-time (but moving space-time itself), conventional relativistic effects (like time dilation) would not apply.
If proven this would make it possible to travel to solar systems light years away such as Alpha Centauri:
In short, the Alcubierre Metric allows for FTL travel without violating the laws of relativity in the conventional sense.
