What is a warp bubble?
« on: 12/10/2015 15:21:17 »
I have a high body weight.
Around it, according to GR create curves spacetime.
This curvature can be considered as a warp bubble?

How did my response to this question get deleted?

I explained that when you have a question like this the most efficient way of arriving at an answer is to do a search on Google which almost always brings up the Wikipedia entry on the subject. In this case I did a search using Google on warp bubble and was lead to this

https://en.wikipedia.org/wiki/Alcubierre_drive
Quote
The Alcubierre drive or Alcubierre warp drive (or Alcubierre metric, referring to metric tensor) is a speculative idea based on a solution of Einstein's field equations in general relativity as proposed by theoretical physicist Miguel Alcubierre, by which a spacecraft could achieve faster-than-light travel if a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created.
...
In 1994, Alcubierre proposed a method for changing the geometry of space by creating a wave that would cause the fabric of space ahead of a spacecraft to contract and the space behind it to expand. 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. It was thought to use too much negative energy until Harold Sonny White said that the amount of energy required could be reduced if the warp bubble were changed into a warp ring.
