The SIMPLE detector is based on superheated droplet detectors (SDDs), a suspension of 1–2% superheated liquid C 2 ClF 5 droplets (~30 μm radius) in a viscoelastic 900 ml gel matrix, which undergo transitions to the gas phase upon energy deposition by incident radiation.
In addition, Abell 85 has its velocity dispersion of dark matter halo at ~750 km/s, which could be explained only by a black hole with a mass greater than 150 billion M ☉, although Kormendy and Ho et al stated that "dark matter halos are scale-free, and the SMBH-dark matter coevolution is independent from the effects of baryons".

Dark matter serves as a plot device in the 1995 X-Files episode "Soft Light". [190] A dark-matter-inspired substance known as "Dust" features prominently in Philip Pullman's His Dark Materials trilogy. [191] Beings made of dark matter are antagonists in Stephen Baxter's Xeelee Sequence. [192]
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 ...
Direct detection of dark matter is the science of attempting to directly measure dark matter collisions in Earth-based experiments. Modern astrophysical measurements, such as from the cosmic microwave background , strongly indicate that 85% of the matter content of the universe is unaccounted for. [ 1 ]
Gravitino dark matter is a possibility in supersymmetric models in which the scale of supersymmetry breaking is low, around 100 TeV. In such models the gravitino is very light, of order an eV . As dark matter, the gravitino is sometimes called a super-WIMP because its interaction strength is much weaker than that of other supersymmetric dark ...
The detectors are filled with liquid argon from underground sources [1] in order to exclude the radioactive isotope 39 Ar, which makes up one in every 10 15 (quadrillion) atoms in atmospheric argon. [2] The Darkside-10 (DS-10) prototype was tested in 2012, and the Darkside-50 (DS-50) experiment has been operating since 2013.
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 ...
