Astronomers look to quark stars for a fifth dimension

New Scientist | Jun. 24, 2007 (News Report)

If the universe has weird extra-spatial dimensions in parallel to the 3D world we see around us, then billion-dollar particle accelerators may not be the only place to find them.

So say Gergely Gabor Barnaföldi and colleagues at the Research Institute for Particle and Nuclear Physics in Budapest, Hungary, who propose that extra dimensions may show their face in areas of extreme gravity around dense stars. Full Story »

It's an interesting article, but could have been made better by mentioning at least some of the difficulties GUTs which posit extra dimensions have had (e.g. that they have yet to make an experimentally-verifiable prediction).
