Dark Matter Mystery While carefully measuring the speed of rotation of galaxies, astronomers stumbled upon a profound cosmic mystery. They could estimate what the rotation speed should be by calculating the mass of all the visible stars and gas, thereby determining the gravity of the galaxy. Much to their surprise, the measurements showed that most galaxies are rotating faster than they should.

DARK MATTER We believe that most of the matter in the universe is dark, i.e. cannot be detected from the light which it emits (or fails to emit). This is stuff which cannot be seen directly -- so what makes us think that it exists at all Its presence is inferred indirectly from the motions of astronomical objects, specifically stellar, galactic, and galaxy cluster/supercluster observations. It ...

A Primer on Dark Matter FIGURE: Superposed on an optical picture of a group of galaxies is an X-ray image taken by ROSAT. The image shows confined hot gas (which produces X-rays) highlighted in false red color. The presence of this confined gas indicates that the gravity exerted in groups and clusters of galaxies is larger than that expected from the observed galaxies. There are many reasons to ...

White dwarfs shed light on dark matter BY JEFF FOUST SPACEFLIGHT NOW Posted: March 23, 2001 A white dwarf, WD 0346, first reported by Nigel C. Hambly and Simon T. Hodgkin in 1997 and subsequently identified as a blue cool white dwarf, an unusual beast that turns bluish as it cools below about 4, 000 Kelvin. The cross-hairs follow the star over the course of 43 years as it exhibits proper motion ...

Transcript of WBAI's Program Explorations in Science of December 3, 1997 Professor Michio Kaku: We are speaking to Professor Stuart Samuel, the spokesperson of a new book called The Bible According to Einstein that will be appear in 1998. The first question is What is dark matter Professor Samuel: Well, dark matter is one of the greatest puzzles of modern astronomy. Everybody loves a mystery ...
