The Alcubierre metric defines the warp-drive spacetime.It is a Lorentzian manifold that, if interpreted in the context of general relativity, allows a warp bubble to appear in previously flat spacetime and move away at effectively faster-than-light speed.
Miguel Alcubierre Moya (born March 28, 1964) is a Mexican theoretical physicist. [4] Alcubierre is known for the proposed Alcubierre drive , a speculative warp drive by which a spacecraft could achieve faster-than-light travel.
Miguel Alcubierre (numerical relativity, Alcubierre drives), ... geometry of gravitational plane waves, impulsive waves, Penrose–Khan colliding plane wave, ...
:Used concepts developed in the then-current textbooks (e.g., vector analysis and non-Euclidean geometry) to provide entry into mathematical physics with a vector-based introduction to quaternions and a primer on matrix notation for linear transformations of 4-vectors. The ten chapters are composed of 4 on kinematics, 3 on quaternion methods ...
This is a list of well-known spacetimes in general relativity. [1] Where the metric tensor is given, a particular choice of coordinates is used, but there are often other useful choices of coordinate available.
In general relativity, the metric tensor (in this context often abbreviated to simply the metric) is the fundamental object of study.The metric captures all the geometric and causal structure of spacetime, being used to define notions such as time, distance, volume, curvature, angle, and separation of the future and the past.
For a simplified notion of a wormhole, space can be visualized as a two-dimensional surface. In this case, a wormhole would appear as a hole in that surface, lead into a 3D tube (the inside surface of a cylinder), then re-emerge at another location on the 2D surface with a hole similar to the entrance.
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.
