Faster-than-light (superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light in vacuum (c). The special theory of relativity implies that only particles with zero rest mass (i.e., photons ) may travel at the speed of light, and that nothing may travel faster.
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.
Physicists generally believe faster-than-light travel is impossible. Relativistic time dilation allows a traveler to experience time more slowly, the closer their speed is to the speed of light. [34] This apparent slowing becomes noticeable when velocities above 80% of the speed of light are attained.
Although it is not possible to travel faster than the speed of light, the effective speed is faster than light. This warping of space and time is precisely mathematically specified by the Lorentz factor, which depends on velocity. Although only theoretical when published over 100 years ago, the effect has since been measured and confirmed many ...
In this, he describes the Alcubierre drive, a theoretical means of traveling faster than light that does not violate the physical principle that nothing can locally travel faster than light. In this paper, he constructed a model that might transport a volume of flat space inside a "bubble" of curved space.
Wormhole travel as envisioned by Les Bossinas for NASA, c. 1998. The impossibility of faster-than-light relative speed applies only locally. Wormholes might allow effective superluminal (faster-than-light) travel by ensuring that the speed of light is not exceeded locally at any time. While traveling through a wormhole, subluminal (slower-than ...
The theory of relativity says information cannot be transmitted faster than light. This experiment does not actually transmit a signal from object 1 to object 2. The time when the light beam strikes object 2 is controlled by the person at the lighthouse, not anyone on object 1, so no one on object 1 can transmit a message to object 2 by this ...
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.
