Crystals could help reveal secrets of dark matter

The flash of a glowing crystal could help us find lighter WIMPs – and answer tough questions about our universe. Also known as weakly interacting massive particles, WIMPS are a theoretical dark matter particle – the mysterious stuff that makes up 85% of the mass of our universe. We know that dark matter is out there, we just have it …

Dark matter only interacts with gravity

Dark matter still presents astronomers with major challenges, as new observations suggest that this mysterious substance interacts only with gravity, but not with the rest of the forces or with itself, contrary to what it said three years ago Andrew Robertson from the British University of Durham presented the results of a study during the European Week of Astronomy and …

A new study could provide the best explanation yet for dark matter

Physicists who seek to understand the basic structure of nature rely on consistent theoretical frameworks that can explain what we see and at the same time make predictions that we can test. On the smallest scale of elementary particles, the standard model of particle physics is the basis of our understanding. On the scale of the cosmos much of our …

Scientists thought they had found dark matter, but we still do not find it, as the latest study shows.

The mystery of dark matter has deepened as scientists reveal that the elusive substance does not interact with galaxies, as previous research suggests. Three years ago, scientists thought they had come one step closer to identifying the mysterious substance, when they discovered that a galaxy was separated from a heap of surrounding dark matter. The discovery – considered a breakthrough …

Dark matter became completely black

In the centers of galaxies, halo is dark matter, which explains the characteristics of the circular motion of stars around the nucleus. An international team of astronomers led by Richard Massey (Richard Massey) of the University of Durham in England denied the "lightening" of dark matter, ie the existence of non-gravitational interactions between lumps of invisible matter. Preprint of the …

Saturn's clouds are deep, rings can rain organic matter – Spaceflight Now

Artistic representation of the internal structure of Saturn. Credit: NASA / JPL-Caltech The Saturn clouds have roots deeper in the planet's atmosphere than the scientists previously thought, and Saturn rings – which are thought to have formed over the last 200 million years – seem to be organic molecules raining on the planet, according to NASA's Cassini spacecraft last year …

ALMA observations show that dark matter does not interact with itself

An earlier study of the galaxy cluster Abell 3827 concluded that dark matter can interact with forces other than gravity. New observations with the Atacama Large Millimeter Array in Chile called the results into question. (19459014) ESO ) It is known that dark matter, which accounts for about 85 percent of matter in the universe, only interacts with ordinary and …

This is (probably) the only way Dark Matter interacts with normal matter

This picture shows the four central galaxies in the Abell 3827 cluster with ultraviolet light from the Hubble images (blue) and infrared light from the ALMA Observations (red). At these wavelengths, scientists can determine the extent to which a galaxy behind the cluster was distorted by the gravitational forces of normal and dark matter.

Dark matter does not interact with itself

Dark matter is still the shyest particle of physics. New observations show that dark matter in the galaxy cluster Abell 3827 stubbornly ignores all other types of matter – including itself, astronomers reported on April 6 at the European Week of Astronomy and Space Science in Liverpool, England. arXiv.org, negates an earlier finding that stars were separated from their dark …
