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]
The discovery of cosmic microwave background radiation constitutes a major development in modern physical cosmology.In 1964, US physicist Arno Allan Penzias and radio-astronomer Robert Woodrow Wilson discovered the cosmic microwave background (CMB), estimating its temperature as 3.5 K, as they experimented with the Holmdel Horn Antenna.
Dark matter is called ‘dark’ because it’s invisible to us and does not measurably interact with anything other than gravity. It could be interspersed between the atoms that make up the Earth ...
The most powerful telescope to be launched into space has made history by detecting a record number of new stars in a distant galaxy. NASA's James Webb Space Telescope, history's largest and most ...
The two Voyager spacecraft have travelled farther than any human-made object in history, and as they reach interstellar space, experts explore their most astonishing discoveries and how their extended operation has transformed into the ultimate mission.
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 visible matter in the Universe, such as stars, adds up to less than 5 percent of the total mass that is known to exist from many other observations. The other 95 percent is dark, either dark matter, which is estimated at 20 percent of the Universe by weight, or dark energy, which makes up the balance. The exact nature of both still is unknown.
