New mathematical model links spacetime theories > http://phys.org/news/201305mathematicallinksspacetimetheories.html
> Spacetime is usually understood to describe space existing in three > dimensions, with time playing the role of a fourth dimension and all > four coming together to form a continuum, or a state in which the > four elements can't be distinguished from each other.
> Flat spacetime and negative spacetime describe an environment in > which the Universe is noncompact, with space extending infinitely, > forever in time, in any direction. The gravitational forces, such as > the ones produced by a star, are best described by flatspace time. > Negatively curved spacetime describes a Universe filled with > negative vacuum energy. The mathematics of holography is best > understood for negatively curved spacetimes.
> Professor Skenderis has developed a mathematic model which finds > striking similarities between flat spacetime and negatively curved > spacetime, with the latter however formulated in a negative number > of dimensions, beyond our realm of physical perception. > > > Read more at: > http://phys.org/news/201305mathematicallinksspacetimetheories.html#jCp
