Crews working on the largest U.S. experiment designed to directly detect dark matter completed a major milestone last month, and are now turning their sights toward startup after experiencing some delays due to global pandemic precautions. U.S. Department of Energy officials on Sept. 21 formally signed off on project completion for LUX-ZEPLIN, or LZ: an ultrasensitive ...
Dark matter is the invisible glue that keeps stars, dust, and gas together in a galaxy. This mysterious substance makes up the bulk of a galaxy’s mass and forms the foundation of our Universe’s large-scale structure. Because dark matter does not emit, absorb, or reflect light, its presence is only known through its gravitational pull ...
For the first time, researchers from Bonn University and Strasbourg University have simulated the formation of galaxies in a universe that works without dark matter. Instead, they modified Newton’s laws of gravity to simulate this process on the computer. A galaxy that is created with computer calculations is similar to those that we actually see today ...
Dark matter, which researchers believe makes up about 80 percent of the universe’s mass, is one of the most elusive mysteries in modern physics. A recent study indicates it may be older than the Big Bang. The study, published in Physical Review Letters, presents a new idea of how this matter was born and how to ...
Dark matter has been a mystery to scientists for a long time. A team of physicists from Vanderbilt University and Case Western Reserve University asked themselves a rather interesting question — “Has dark matter killed anyone?” Dark matter and death Macro dark matter particles are known to elastically scatter regular matter across a wide geometric ...
Think you have never come in contact with dark matter? You couldn’t be more wrong. The average human body gets hit by a dark matter particle once every minute according to Katherine Freese from the University of Michigan and Christopher Savage from Stockholm University. Dark matter and the human body Dark matter is a hypothetical ...
As fascinating as it is mysterious, dark matter is one of the greatest enigmas of astrophysics and cosmology. It is thought to account for 90 percent of the matter in the Universe, but its existence has been demonstrated only indirectly and recently called into question. New research conducted by SISSA removes the recent doubts on the ...
How do you observe a process that takes more than 1 trillion times longer than the age of the universe? The XENON Collaboration research team did it with an instrument built to find the most elusive particle in the universe — dark matter. In a paper published in the journal Nature, researchers announced that they have observed the ...
After drawing both praise and skepticism, the team of astronomers who discovered NGC 1052-DF2 — the very first known galaxy to contain little to no dark matter — is back with stronger evidence about its bizarre nature. Dark matter is a mysterious, invisible substance that typically dominates the makeup of galaxies; finding an object missing ...
Dark matter is literally the most abundant matter in our universe. However, scientists are yet to detect it even after trying hard for the past few decades. Some blame the excessive focus on detecting Weakly Interacting Massive Particles (WIMP) as a reason for this and are calling for new kinds of experiments on dark matter. ...
