Shape of the Universe

The shape of the Universe is a subject of investigation within physical cosmology.

Cosmologists and astronomers describe the geometry of the Universe which includes both local geometry and global geometry.

The shape of the universe can be determined by measuring the average density of matter within it, assuming that all matter is evenly distributed, rather than the distortions caused by 'dense' objects such as galaxies.

This assumption is justified by the observations that, while the universe is "weakly" inhomogeneous and anisotropic (see the large-scale structure of the cosmos), it is on average homogeneous and isotropic.

Considerations of the geometry of the universe can be split into two parts; the local geometry relates to the observable universe, while the global geometry relates to the universe as a whole - including that which we can't measure.

Physicists Seek Animated Answers to Dark Secrets of the Universe

Reuters (Nov. 29, 2012) Physicists at the Argonne National Laboratory in Illinois hope to unravel the mysteries of dark matter and dark energy with the most detailed computer simulations of the universe ever built. The two theoretical forces have never been detected but are believed to make up more than 95 percent of the universe The researchers want to know what the forces are and how they work.

Astronomy What Is the Phenomenon Called "Dark Energy"?

Deutsche Welle (July 8, 2012) Last year the Nobel Prize for Physics was awarded for the discovery that the universe is expanding at an increasing pace. The reason, according to theory, has to be an unknown, dark energy. German astrophysicist Thomas Reiprich set out to find out more about this phenomenon, for example, how much of the stuff exists. His tools might seem modest: telescope shots of galaxies and high-performance computers. Reiprich's work, however, addresses a major issue in the world of astrophysics, and further Nobel Prizes coming from this area are not unlikely.
