Thanks for the post. I want to know, but not so much I'm about to dive into superstrings or M theory or the such. I think I'll focus on trying to understand what "time to diffuse according to the Schrodinger equation" means for now.
It is definitely an intentional part of my question that this is *NOT* a gradual change. Let's say this is a weapon of an advanced, alien civilization. I want to know what happens when the source is just GONE, not moving at a pleasant, manageable <c.
You could rephrase this as "Aliens...
From http://en.wikipedia.org/wiki/Speed_of_gravity
"Several physicists, including Clifford M. Will and Steve Carlip, have criticized these claims on the grounds that they have allegedly misinterpreted the results of their measurements. Notably, prior to the actual transit, Hideki Asada in a...
1 vote for the 'speed of light' column. Would there be any practical way to test this? Or has such a test already happened and I just don't know about it? As I understand it, general relativity said that basically nothing can happen faster than speed of light in vacuum, including the...
I've wanted to know this for 15 years. If every particle in the sun simultaneously tunneled to another galaxy, how long would it take the Earth to stop orbiting as if the sun were there? 0 seconds? ~7 minutes? Why? How fast does space-time un-deform?
