I apologize tremendously if this is in the wrong spot -- I couldn't decide between here and the "Beyond the Standard Model" subforum. Background (Not terribly relevant) I'm a "hobbyist" when it comes to physics. For me, it's one of those things that, had circumstances been different, I would've devoted life to studying. Instead, I'm an animator, which is where my heart ultimately ended up leading me. However, I still maintain an avid interest in physics of all sorts, but particularly with respect to "sci-fi" technologies that hold the promise of losing their fictional aspect. To that end, I was very intrigued when I first read about Alcubierre's metric on the BPP website, but dismayed to find the paper unavailable at the time. Recently, as part of an animation-related project I'm pursuing, it's come to the forefront of my thought again. Fortunately, arxiv.org is around now and his paper, along with many others, are now available to everyone. The Problem The trouble is, I barely understand the equations I'm looking at. The papers assume a certain level of expertise and variable recognition that I simply lack. Beyond a purely academic interest in the topic, I'm interested in developing an understanding of the Alcubierre equation(s) that I can use to plug in a radius for a warp bubble, a desired "speed," and provide an "power requirement" as a result. As I understand it, the initial paper was refined by Chris Van Den Broeck, and then refined further such that the quantity of negative energy required was on the order of about -10 kg (though I've no idea what this -10kg will "get you" as far as the size and speed of the bubble go, nor if it's actually representative of anything approaching a "power requirement"). Please help So, what I'm looking for specifically is a watered-down version of the metric that I can use to plug in two values (speed and radius) and produce a third (energy/power requirement). However, in the more global sense, I would love it if someone could guide me through a sort of "Alcubierre for dummies," explaining what the equations all mean. Thanks a bunch! This is a fantastic forum you've got here, and I look forward to learning a lot here.
