Is Alcubierre drive possible?
Although the metric proposed by Alcubierre is consistent with the Einstein field equations, construction of such a drive is not necessarily possible. The proposed mechanism of the Alcubierre drive implies a negative energy density and therefore requires exotic matter or manipulation of dark energy.
How long would it take to get to Alpha Centauri with Alcubierre drive?
The Alcubierre bubble could get to Alpha Centauri in less than 4 years according to outside observers, not just observers riding inside the bubble–the exact time depends on the exact ‘shape’ of the warped spacetime in the bubble, but the theory allows you to fine-tune the bubble to give as short a time as desired.
How fast would an Alcubierre drive go?
A warp(Alcubierre) drive can go ~10c without being affected by time dilation. A space vessel can go up to but not as fast as the speed of light.
Would an Alcubierre drive time dilation?
This means that even though the coordinate acceleration can be an arbitrary function of time, the proper acceleration along the spaceship’s path will always be zero. So the Drive itself causes no time dilation for the occupants of the ‘warp field bubble’.
How long would it take Voyager 1 to reach Alpha Centauri?
It will take 20,000 years for our earliest probes to reach Alpha Centauri. Some of the earliest explorations of the universe beyond our solar system were made by four probes launched by NASA in the 1970s — Pioneer 10 and 11 and Voyager 1 and 2.
Has NASA made a warp drive?
DARPA and NASA Scientists Accidentally Create Warp Bubble for Interstellar Travel. A Defense Advanced Research Projects Agency-funded research project at NASA’s Johnson Space Center may have accidentally discovered how to build a warp drive engine. The scientists published their findings in July.
How close are we to making a warp drive?
Though significant, we’re still a long way before interstellar travel and warp drive becomes a reality. However, with advancements in technology, the answers we’re looking for might be close enough. According to Star Trek, warp drive was invented in 2063.
Did DARPA really create a warp bubble?
Would the Alcubierre drive work in real life?
Although the Alcubierre drive was possible within general relativity, it only worked if you could get your hands on a planet’s worth of some kind of exotic material that has negative mass. All known matter has positive mass, so that’s kind of a deal-breaker. Even Alcubierre has said the idea probably wouldn’t work in real life.
Is Alcubierre’s metric for drive possible?
Although the metric proposed by Alcubierre is consistent with the Einstein field equations, it may not be physically meaningful, in which case a drive will not be possible. Even if it is physically meaningful, its possibility would not necessarily mean that a drive can be constructed.
Did Miguel Alcubierre invent warp drive?
For example, physicist and science-fiction author Robert Forward proposed several ideas. But things really took off when Miguel Alcubierre published a paper in Classical and Quantum Gravity that could truly be called warp drive. An illustration of the Alcubierre warp effect.

How did Miguel Alcubierre change the geometry of space?
In 1994, Miguel Alcubierre proposed a method for changing the geometry of space by creating a wave that would cause the fabric of space ahead of a spacecraft to contract and the space behind it to expand.
