The microorganisms were found in organically poor sediments 68.9 metres (226 feet) below the seafloor in the South Pacific Gyre (SPG), "the deadest spot in the ocean". [269] [270] Unidentified spherical algal microorganism, part of the microbial dark matter
Astronomical searches for gravitational microlensing in the Milky Way found at most only a small fraction of the dark matter may be in dark, compact, conventional objects (MACHOs, etc.); the excluded range of object masses is from half the Earth's mass up to 30 solar masses, which covers nearly all the plausible candidates.
In the ocean, the aphotic zone is sometimes referred to as the dark ocean. Depending on how it is defined, the aphotic zone of the ocean begins between depths of about 200 m (660 ft) to 800 m (2,600 ft) and extends to the ocean floor .
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 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 ...
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 ...
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.
Therefore, they seem to be dark-matter-dominated even in their centers, which makes them excellent laboratories for the study of dark matter. In comparison to the high-surface-brightness galaxies, LSBs are mainly isolated field galaxies, found in regions devoid of other galaxies. In their past, they had fewer tidal interactions or mergers with ...
