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 ...
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 approximate dividing line is warm dark matter became non-relativistic when the universe was approximately 1 year old and 1 millionth of its present size and in the radiation-dominated era (photons and neutrinos), with a photon temperature 2.7 million Kelvins.
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.
Dark matter is a mysterious, invisible substance makes up more than 80 percent of all matter in the universe Science has found its first candidate for a dark-matter detector. It’s a really old rock
The act of creation is the establishment of an inhabitable space separate from the enveloping waters. [1] The cosmic ocean is the shape of the universe before creation. [2] The ocean is boundless, unordered, unorganized, amorphous, formless, dangerous, terrible. In some myths, its cacophony is noted, opposed to the ordered rhythm of the sea. [3]
The researchers used a year of observations by the Dark Energy Spectroscopic Instrument (DESI) at Kitt Peak National Observatory in Arizona, which can capture light from 5,000 galaxies simultaneously.
