Comment: This is one of those theoretical physics studies giving a glimmer of hope that such a thing as warp speed is possible. The speed of light has been a standard for a long time as a limit.

"In 1994, theoretical physicist Miguel Alcubierre found a solution that distorted space in a way very similar to that originally envisioned by the creators of Star Trek. Under exactly the right conditions, it is possible to expand space behind an object and compress it in front."
Quote from Wikipedia: https://en.wikipedia.org/wiki/Miguel_Alcubierre
Alcubierre is best known for the proposal of "The Warp Drive: Hyper-fast travel within general relativity" that was published in the science journal Classical and Quantum Gravity.[13] 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. This bubble, named as Hyper-relativistic local-dynamic space, is driven forward by a local expansion of space-time behind it, and an opposite contraction in front of it, so that theoretically a spaceship would be placed in motion by forces generated in the change made by space-time.
