摘要
The subject of analogue (or simulated) gravity has become a large area with the number of papers being of the order of a thousand. I will discuss a few types of analogues focussing on the relation between the actual gravitational field and and a fluid simulation of the field. In a sense this is directly related to specific coordinate systems for the gravitational field.
Concrete simulations for the Schwarzschild and Kerr gravitational fields will be presented. At the end of the talk I will also present a demonstrational analogue of the Schwarzschild field which relates to recent astronomical observations.
