Understanding the Alcubierre Solution
At the heart of the Alcubierre solution lies a central region of what is termed ordinary flat spacetime. Behind this, the fabric of space expands, propelling the passengers forward, akin to how the universe is currently expanding and distancing galaxies. Passengers within the warp bubble can remain stationary while the surrounding spacetime moves—similar to being on a conveyor belt at an airport. This intriguing concept raises the question: how does one actually warp space?
