A new study claims to have found an explanation for dark matter but relies on the discovery of a particle that leads to another dimension. #fifthdimension #5thDimension
A team of researchers believes that they have found a natural explanation for dark matter and a number of other scientific oddities that have so far defied explanation, but their work hinges on the existence of a new theoretical subatomic particle as well as an entirely new “warped fifth dimension” of the universe. #5D #fifthdimension #darkmatter
Researchers at the Institute for Basic Science (IBS) have recently carried out a search for invisible axion dark matter using a multiple-cell cavity haloscope that they designed. Their results compared favorably to those of previous haloscope-based axion dark matter searches, highlighting the potential of the instrument they created for both dark matter searches and other physics research. #darkmatter
The missing dark matter in certain galaxies can be explained by the effects of tidal disruption: the gravity forces of a neighboring massive galaxy, literally tearing the smaller galaxy apart. #darkmatter
Scientists can see how dark matter is distributed based on how its gravity affects light, but when astronomers compared recent data from the Hubble Space Telescope and the Very Large Telescope to current models, something didn’t add up. #darkmatter #sciencenews
Astronomers may have detected signatures of elusive dark matter — a mysterious, invisible material that permeates the universe, but has so far proved undetectable.

Through the analysis of light from distant galactic clusters, astronomers have detected a mysterious signal that they’re having a hard time explaining. Although the signal is weak, could it be the much sought-after direct evidence for dark matter? Dark matter pervades the entire universe and makes up for the bulk of its mass, but what is it? We know it’s out there and oodles of indirect evidence for its presence, but seeing a direct signal has so far proven elusive.
The hidden tendrils of dark matter that underlie the visible Universe may have been traced out for the first time. Cosmology theory predicts that galaxies are embedded in a cosmic web of “stuff”, most of which is dark matter. Astronomers obtained the first direct images of a part of this network, by exploiting the fact that a luminous object called a quasar can act as a natural “cosmic flashlight”. The quasar illuminates a nearby gas cloud measuring two million light-years across.
