Alcubierre revealed that the warp drive from « Star Trek » was in fact theoretically possible.Proxima Centauri here we come? Image through Tokamac/Wikimedia Commons, CC BY-SAA unfavorable energy problemAlcubierres warp drive would work by creating a bubble of flat spacetime around the spaceship and curving spacetime around that bubble to lower ranges. Alcubierres warp drive would use this unfavorable energy to develop the spacetime bubble.But for a warp drive to generate sufficient unfavorable energy, you would need a lot of matter.

Another technique– familiar to « Star Trek » fans– is warp drive technology. 2 current papers made headings in March when scientists claimed to have conquered one of the many obstacles that stand in between the theory of warp drives and reality.But how do these theoretical warp drives truly work?

Image by means of Tokamac/Wikimedia Commons, CC BY-SAA unfavorable energy problemAlcubierres warp drive would work by creating a bubble of flat spacetime around the spaceship and curving spacetime around that bubble to lower distances. Alcubierres warp drive would use this negative energy to produce the spacetime bubble.But for a warp drive to produce enough negative energy, you would require a lot of matter.

Another approach– familiar to « Star Trek » fans– is warp drive innovation. Warp drives are theoretically possible if still far-fetched technology. 2 recent papers made headings in March when researchers declared to have overcome one of the many obstacles that stand in between the theory of warp drives and reality.But how do these theoretical warp drives actually work?
