In astronomy, dark matter is a 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.
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 oxygen production refers to the generation of molecular oxygen (O 2) through processes that do not involve light-dependent oxygenic photosynthesis.The name therefore uses a different sense of 'dark' than that used in the phrase "biological dark matter" (for example) which indicates obscurity to scientific assessment rather than the photometric meaning.
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 ...
New research challenges a long-held assumption about oxygen in the deep sea, with scientists finding oxygen produced without photosynthesis in the Clarion-Clipperton Zone.
The universe's contents include ordinary matter - stars, planets, gas, dust and all the familiar stuff on Earth, including people and popcorn - as well as dark matter, which is invisible material ...
A cosmic ocean, cosmic sea, primordial waters, or celestial river is a mythological motif that represents the world or cosmos enveloped by a vast primordial ocean. Found in many cultures and civilizations, the cosmic ocean exists before the creation of the earth. From the primordial waters the earth and the entire cosmos arose.
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 ...
