Warp drive, or a drive enabling space warp, is one of several ways of travelling through space found in science fiction. [3] It has been often discussed as being conceptually similar to hyperspace. [3] [4]: 238–239 A warp drive is a device that distorts the shape of the space-time continuum.
The Alcubierre drive ([alkuˈβjere]) is a speculative warp drive idea according to which a spacecraft could achieve apparent faster-than-light travel by contracting space in front of it and expanding space behind it, under the assumption that a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created.
The idea of a warp drive is particularly appealing because it’s technically describable within general relativity, as the Mexican theoretical physicist Miguel Alcubierre proposed back in 1994.
The Alcubierre drive uses exotic matter (not to be confused with antimatter) to travel faster than light. While the concept had been out since 2013 the design of IXS Enterprise was popularized in June 2014 after a series of media outlets reported on the conceptual artwork done by Dutch artist Mark Rademaker in collaboration with NASA.

A revolutionary study introduces a warp drive model compatible with known physics, offering a scientifically grounded approach to faster-than-light travel.
The Breakthrough Propulsion Physics project addressed a selection of "incremental and affordable" research questions towards the overall goal of propellantless propulsion, hyperfast travel, and breakthrough propulsion methods. [3] It selected and funded five external projects, two in-house tasks and one minor grant. [2]
Certain kinds of hypothetical spacetimes called warp drives, which in a sense can be said to admit a kind of faster-than-light inertia-less and time-dilation-less travel, have been studied by some theoretical physicists since about 1990. This category contains articles related to such theoretical speculations.
