Editing Alcubierre drive (section)

==History==
In 1994, [[Miguel Alcubierre]] proposed a method for changing the [[Shape of the universe|geometry of space]] by creating a wave that would cause the fabric of space ahead of a [[Starship|spacecraft]] to contract and the space behind it to expand.<ref name="Alcubierre" /><ref name="AIAA-20190816">{{Cite journal |last=Agnew |first=J. |date=16 August 2019 |title=An Examination of Warp Theory and Technology to Determine the State of the Art and Feasibility |journal=[[American Institute of Aeronautics and Astronautics#Conferences|AIAA Propulsion and Energy Forum and Exposition]] |doi=10.2514/6.2019-4288 |isbn=978-1-62410-590-6 |s2cid=202443606}}</ref><ref name="SA-20200301">{{Cite news |last=Williams |first=Matt |date=1 March 2020 |title=Scientists Are Starting to Take Warp Drives Seriously, Especially This One Concept |work=ScienceAlert.com |url=https://www.sciencealert.com/scientists-are-starting-to-take-warp-drives-seriously-especially-this-one-concept}}</ref> The ship would then ride this wave inside a region of flat space, known as a ''warp bubble'', and would not move within this bubble but instead be carried along as the region itself moves due to the actions of the drive. The local velocity relative to the deformed spacetime would be subluminal, but the speed at which a spacecraft could move would be superluminal, thereby rendering possible interstellar flight, such as a visit to ''[[Proxima Centauri]]'' within a few days.<ref name=":1">{{Cite journal |last1=Fil'chenkov |first1=M. |last2=Laptev |first2=Yu. |date=2017-10-01 |title=Galaxy travel via Alcubierre's warp drive |url=https://www.sciencedirect.com/science/article/pii/S0094576517301637 |journal=Acta Astronautica |language=en |volume=139 |pages=254–257 |doi=10.1016/j.actaastro.2017.07.011 |bibcode=2017AcAau.139..254F |issn=0094-5765}}</ref>
