A dark matter map, created by Japanese astronomers using weak lensing. The background image of a wide field of galaxies was analyzed for weak lensing effects and the inferred dark matter distribution is indicated with the contours. Credit: Satoshi Miyazaki About 85% of the matter in the univers...
visible galaxies. Scientists believe that 80 to 90 percent of the universe must be made of this as-yet-undetected matter to account for the observed structure of the universe. According to Einstein, such high concentrations of matter should warp the surrounding ...
根据第一段“There simply isn’t enough mass in stars, gas, and dust to explain why galaxies aren’t flying apart. The solution to this problem is to postulate (假定) the existence of dark matter, a hypothetical (假定的) substance that can’t be seen but whose presence can be inferred ...
Dark matter appears to be spread across the cosmos in a network-like pattern, with galaxy clusters forming at the nodes where fibers intersect.(Image credit: WGBH) Studies of gas within elliptical galaxies also indicated a need for more mass than found in visible objects. Clusters of galaxies ...
Dark matter is a mysterious invisible substance that makes up around 85 per cent of all the matter in the universe. Scientists know it's there only because it exerts a powerful gravitational force on visible stars and galaxies, influencing the way they move. Since the 1930s, evidence has gro...
Dark matterGalaxiesCosmologyThe evidence of the phenomenon for which, in galaxies, the gravitating mass is distributed differently than the luminous mass, increases as new data become available. Furthermore, this discrepancy is well structured and it depends on the magnitude and the compactness of ...
of the universe, visible matter, ranging in size from the tiniest speck of dust to massive celestial bodies like Earth, even whole galaxies, constitutes only about 5 percent of the total mass of the cosmos. The remaining 95 percent is believed to be comprised of dark matter and dark energy...
results; the ROSAT satellite has provided extended X-ray maps of the hot gas, which traces dark matter in galaxy clusters: they reveal lower amounts of dark matter in clusters than was previously derived; the dark to visible mass in clusters is not larger than its value in spiral galaxies....
