New Scientist, Feb. 11, 2006, has a fascinating article by Paul Wesson, an astrophysicist.
"Enter the Void"
According to the standard Einstein theory of relativity you get killed it you travel through a black hole.
In the 5-D black hole-Big Bounce universe: "there is no physical plughole and the tidal forces are negligible, so you could happily explore without fear of dismemberment. And according to the results of my research, you may be doing that right now."
Wesson argues that the Big Bounce cosmology gets science past the problems of the "singularity" where physics breaks down in mathematical infinities.
The Big Bounce, using five dimensions (four of space and one of time) describes the creation of matter as a "phase change" -- just as bubbles form in boiling water.
The "invariant" or constant of the Big Bounce universe called the "Kretschmann scalar" is the same as the result for a 5-D black hole. In other words by swaping the radius of the black-hole for the distance measure in the Big Bounce universe we get the same result.
"The question is, is the coincidence of these numbers due to chance, or to some deepy physics?"
Astronomers agree there is a black hole as the center of the Milky Way, and that the black hole dynamics also describe the dynamics of the universe as a whole but with 5-D the mathematics is not only precise:
5-D enables science to overcome the problem of missing mass which until now has not been able to explain how the universe could fold back upon itself. Light travels in a circle for the universe -- not just once -- but as a spiral!
"While astronomers now believe that there is not enough matter in the universe to make its 3D (ordinary space) part curve positively, Pathria's work on the parallels between black holes and universes still seems curiously prescient: perhaps all he really lacked was an extra dimension."
