I tried a cursory search for this but couldn't find it.
I was talking with my advisor about 5D theories such as those of Paul Wesson and Randall-Sundrum, and he said that I shouldn't spend too much time studying those theories because they are unstable, or require so many corrections to stabilize them that they become intractable. However, I find them intriguing anyway. I want to understand the stability problems he was talking about, such as imaginary mass and gravitational collapse of the extra dimension.
He gave me a paper that talked a little about it but I'm still not grasping what makes these theories so unstable so I might avoid this if I try to build my own model (as a side project to my main research).
Thanks.
