Can warp drives travel faster than light?
A warp drive or a drive enabling space warp is a fictional superluminal (faster than the speed of light) spacecraft propulsion system in many science fiction works, most notably Star Trek, [1] and a subject of ongoing physics research.

The story of warp drives starts with Einstein’s crowning achievement: general relativity. The equations of general relativity capture the way in which spacetime – the very fabric of reality – bends in response to the presence of matter and energy which, in turn, explains how matter and energy move. General relativity places two constraints on inter...
This is where Alcubierre came in. He argued that the mathematics of general relativity allowed for “warp bubbles” – regions where matter and energy were arranged in such a way as to bend spacetime in front of the bubble and expand it to the rear in a way that allowed a “flat” area inside the bubble to travel faster than light.

How does Alcubierre’s device work? Here discussion often relies on analogies, because the maths is so complex. Imagine a rug with a cup on it. You’re on the rug and you want to get to the cup. You could move across the rug, or tug the rug toward you. The warp drive is like tugging on spacetime to bring your destination closer. But analogies have th...
Bobrick and Martire show that any warp drive must be a shell of material in a constant state of motion, enclosing a flat region of spacetime. The energy of the shell modifies the properties of the spacetime region inside it. This might not sound like much of a discovery, but until now it was unclear what warp drives might be, physically speaking. T...
Remember that a warp drive can modify the region of flat spacetime it encloses. It can, in particular, speed up or slow down a clock inside the drive. Consider what it would mean to have such an object available. Want to put someone with a terminal illness on ice? Stick them in a warp drive and slow their clock down. From their perspective, a few y...

Apr 23, 2021 · Another approach – familiar to “Star Trek” fans – is warp drive technology. Warp drives are theoretically possible if still far-fetched technology.
May 23, 2024 · The goal of a warp drive is to get from A to B in the time between commercial breaks, which typically involves faster-than-light motion. But special relativity expressly...
Aug 4, 2024 · New research explored the gravitational waves emitted during a theoretical warp drive failure. The findings suggest that although current technology cannot detect such signals, future advancements may allow us to use these signals to probe deeper into the nature of spacetime and the universe.
May 7, 2024 · A new study provides some theoretical underpinning to warp drives, suggesting that the superfast propulsion tech may not forever elude humanity. Sci-fi fans — especially " Star Trek "...
May 10, 2024 · A revolutionary study introduces a warp drive model compatible with known physics, offering a scientifically grounded approach to faster-than-light travel.
