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.

What does the Alcubierre drive do?

Alcubierre’s warp drive would work by creating a bubble of flat spacetime around the spaceship and curving spacetime around that bubble to reduce distances. The warp drive would require either negative mass – a theorized type of matter – or a ring of negative energy density to work.

When was the Alcubierre drive?

1994
In 1994, physicist Miguel Alcubierre proposed a radical technology that would allow faster than light travel: the warp drive, a hypothetical way to skirt around the universe’s ultimate speed limit by bending the fabric of reality.

Is NASA making a warp drive?

According to Popular Mechanics, the NASA warp drive will expend a massive amount of energy that will “warp” (contract and twist) space time behind the spacecraft, which will create a space time “bubble.” This bubble, which will be created around the ship and curved behind it, will theoretically reduce the distance that …

Does Alcubierre drive cause 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’.

Is NASA building a warp drive?

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.

Did DARPA create a warp bubble?

The world’s first warp bubble emerged as a recent accidental discovery by DARPA-funded researchers, according to the latest report. The Limitless Space Institute (LS) team led by former NASA warp drive expert Dr.

How fast can the Alcubierre drive go?

This answer states that the Alcubierre drive tops out at about 10c.
