Probing the unsolved mystery of dark matter - Northwestern Now
2 天之前 · Assuming dark matter exists, its interactions with ordinary matter are so subtle that even the most sensitive instruments cannot detect them. In a new study, Northwestern University physicists now introduce a highly sensitive new tool, which amplifies incredibly faint signals by 1,000 times — a 50-fold improvement over what was previously possible.
Scientists may have found an answer to the mystery of dark matter…
2024年6月17日 · Scientists studying the earliest black holes may have found an explanation for dark matter, putting Stephen Hawking’s theory on the subject back into the spotlight.
New dark matter map reveals cosmic mystery - BBC
2021年5月27日 · The map shows how dark matter sprawls across the Universe. The black areas are vast areas of nothingness, called voids, where the laws of physics might be different.
To crack the mystery of dark matter, physicists turn to ... - Science
2022年4月28日 · For decades, physicists have struggled to figure out what the stuff is, stalking one hypothetical particle after another, only to come up empty. However, if dark matter consists of certain nearly massless particles, then in the right setting …
After Decades of Searching, Are Physicists Closing In on Dark Matter ...
2024年10月25日 · Scientists are now turning to a wider array of search strategies—and a longer list of potential dark matter candidates—in an effort to crack the almost century-old mystery.
MIT physicist on mystery of dark matter in Harvard talk
2022年10月26日 · MIT physicist Peter Fisher showed a slide of the Andromeda galaxy, with its lush swirl of stars emanating out in a flat disc, containing roughly a trillion stars. Scientists know that dark matter exists because although we can’t see it, we can see the effects of what it does in the world, sort of like a ghost bumping around a haunted house.

A nearby supernova could end the search for dark matter
2024年11月21日 · The most likely dark matter candidate today is the axion, a lightweight particle that researchers around the world are desperately trying to find. Astrophysicists at the University of California, Berkeley, now argue that the axion could be discovered within seconds of the detection of gamma rays from a nearby supernova explosion. Axions, if ...
New Study Reveals Possible Origins of Dark Matter in “Dark Big …
2024年11月19日 · In this model, dark matter particles are produced via the decay of a quantum field that only couples to the Dark Sector and is initially trapped in a false metastable vacuum state. In their recent study [2], Ilie and Casey explore and refine this Dark Big Bang model by determining all the possible scenarios for its realization that remain ...
