Mention of dark matter is made in works of fiction. In such cases, it is usually attributed extraordinary physical or magical properties, thus becoming inconsistent with the hypothesized properties of dark matter in physics and cosmology. For example: Dark matter serves as a plot device in the 1995 X-Files episode "Soft Light". [190]
The second class are those which try to find voids via the geometrical structures in the dark matter distribution as suggested by the galaxies. [29] The third class is made of those finders which identify structures dynamically by using gravitationally unstable points in the distribution of dark matter. [30]
Based on the 2013 data, the universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy. On 5 February 2015, new data was released by the Planck mission, according to which the age of the universe is 13.799 ± 0.021 billion years old and the Hubble constant was measured to be 67.74 ± 0.46 (km/s)/Mpc .
Scientists studying the earliest black holes may have found an answer to dark matter, putting Stephen Hawking’s theory on the subject back into the spotlight. Scientists may have found an answer ...
Dark matter may not give off any light or radiation, but we might be able to watch it smash into atoms here on Earth. Dark matter makes up 85% of all matter in the Universe, but astronomers have ...
The results show that cold dark matter produces a reasonable match to observations, but hot dark matter does not. The sky at energies above 100 MeV observed by the Energetic Gamma Ray Experiment Telescope (EGRET) of the Compton Gamma Ray Observatory (CGRO) satellite (1991–2000). 1988 – The CfA2 Great Wall is discovered in the CfA2 redshift ...
Another important result from the HDF was the very small number of foreground stars present. For years astronomers had been puzzling over the nature of dark matter, mass which seems to be undetectable but which observations implied made up about 85% of all matter in the Universe by mass. [20]
The distribution of matter in the early universe was in clumps that consisted mostly of dark matter. These clumps interacted gravitationally, putting tidal torques on each other that acted to give them some angular momentum. As the baryonic matter cooled, it dissipated some energy and contracted toward the center. With angular momentum ...
