In astronomy, dark matter is an invisible and hypothetical form of matter that does not interact with light or other electromagnetic radiation.Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be observed.
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 .
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 three most popular methods through the study of cosmic voids are listed below.
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 team's findings, which were published Monday in the journal Nature, also unveil a method of investigating dark matter, which remains one of the universe's greatest mysteries, study co-author ...
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 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 ...
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 ...
