What is the gravitational field of a hole in an infinite perfect crystal?
Or equivalently and more interestingly: In the early universe when there was uniform H/He gas everywhere, gravitational field was close to 0 everywhere. Every test particle was pulled from all sides ...

How would an Alcubierre warp bubble be affected by external gravitational fields (e.g. black holes)?
Consider a spaceship inside an Alcubierre warp bubble traveling in a straight trajectory. As it travels, it passes near a black hole (for the sake of argument, we'll say it's near the event horizon of ...

What is a good way to visualize the movement of an Alcubierre drive? [closed]
So I know that an AD works by pinching space-time in front of the ship and expanding it behind the ship.
A good way to describe gravity is having a blanket stretched out on all four corners and ...

Is the Alcubierre drive consistent with conservation of energy? (Gravitational potential in particular)
Consider a ship in a circular orbit around a planet. It activates an Alcubierre drive. Do the physics of this drive allow the ship to reach a greater distance from the planet, and if so, where does ...

Derivation for Alcubierre Drive
Is there any online derivation for the Alcubierre Drive? I have looked at several papers and none of them actually derive the equations. They simply point them out. Particularly, I would like a ...

"Warp-drive" thought experiment
Why wouldn't this "warp-drive" work? Assuming we can build a flywheel that can survive near light speed and have an onboard power storage or beamed energy that can spin it up to that speed and back ...

Can the Alcubierre Drive be explained by Gravitoelectromagnetism? [closed]
Even though there is no experimental evidence, that the Alcubierre drive works. The Einstein field equations permit this solution. For Gravitoelectromagnetism there are hints and ongoing efforts to ...

Relationship between Alcubierre drive space-time evolution and speed of gravity
The top rated answer to this question about the Alcubierre drive asserts, "spacetime can dynamically evolve in a way which apparently violates special relativity," but according to the Wikipedia ...
