College Physics for AP Courses 2015-08-12T00:00:00Z So physicists assume that some sort of invisible dark matter—presumably, a new particle—provides the extra gravity needed to rein in the stars. Dark matter hunt heats up with first result from world’s biggest detector 2022-07-06T04:00:00Z Conventional wisdom holds that in the early universe, pools of dark matter—specifically, “cold” dark matter, a type of dark matter composed of sluggish, slow-moving particles—attracted gas that gave rise to the first stars. JWST’s Glimpses of Early Galaxies Could Shed Light on Dark Matter 2023-06-20T04:00:00Z We should add that the problem of dark matter is by no means confined to the Milky Way. Astronomy 2016-10-13T00:00:00Z One part of the mystery is dark matter, which has by far most of the mass in the cosmos. Huge underground search for mysterious dark matter begins 2022-07-07T04:00:00Z To date, a few MACHOs have been observed, but not predominantly in galactic halos, nor in the numbers needed to explain dark matter. College Physics for AP Courses 2015-08-12T00:00:00Z Since the 1980s, many physicists have thought dark matter consists of WIMPs, which would interact with ordinary matter just through gravity and the weak nuclear force. Dark matter hunt heats up with first result from world’s biggest detector 2022-07-06T04:00:00Z But every experiment to find cold dark matter has failed, leaving some astronomers wondering if they should instead be searching for alternative forms. JWST’s Glimpses of Early Galaxies Could Shed Light on Dark Matter 2023-06-20T04:00:00Z This dark matter is located mostly in the Galaxy’s halo; its nature is not well understood at present. Astronomy 2016-10-13T00:00:00Z “It is essentially impossible to understand our observation of history, of the evolutionary cosmos without dark matter,” Manalaysay said. Huge underground search for mysterious dark matter begins 2022-07-07T04:00:00Z MACHOs are among the most conventional of unseen objects proposed to explain dark matter. College Physics for AP Courses 2015-08-12T00:00:00Z WIMPs would have emerged naturally after the big bang and should linger in sufficient numbers to account for dark matter, provided they are about 100 times as massive as a proton. Dark matter hunt heats up with first result from world’s biggest detector 2022-07-06T04:00:00Z If, early on, the universe had been filled with some entirely different type of dark matter, what kinds of galaxies would have followed?

College Physics for AP Courses 2015-08-12T00:00:00Z For instance, the Higgs boson might decay into dark matter, or Higgs decays may violate the expected symmetry between matter and antimatter. 10 Years after the Higgs, Physicists Are Optimistic for More Discoveries 2022-07-05T04:00:00Z “The cool thing for me was seeing different dark matter models all explored simultaneously.” JWST’s Glimpses of Early Galaxies Could Shed Light on Dark Matter 2023-06-20T04:00:00Z This single number tells us roughly what kind of stars make up most of the luminous population of the galaxy, and it also tells us whether a lot of dark matter is present. Astronomy 2016-10-13T00:00:00Z So while there’s little doubt that dark matter exists, there’s lots of doubt about what it is. Huge underground search for mysterious dark matter begins 2022-07-07T04:00:00Z Such calculations are used to imply the existence of “dark matter” in the universe and have indicated, for example, the existence of very massive black holes at the centers of some galaxies. College Physics for AP Courses 2015-08-12T00:00:00Z Many models that try to explain dark matter propose the existence of exotic long-lived particles that may penetrate through the inner detectors and arrive in the outer detectors before decaying to standard particles. 10 Years after the Higgs, Physicists Are Optimistic for More Discoveries 2022-07-05T04:00:00Z Many suspected the universe’s galaxies were seated within giant dark matter clouds, called “halos,” many times larger than the galaxies themselves. JWST’s Glimpses of Early Galaxies Could Shed Light on Dark Matter 2023-06-20T04:00:00Z It is somewhat surprising that this technique works, since much of the mass associated with galaxies is dark matter, which does not contribute at all to the luminosity but does affect the rotation speed. Astronomy 2016-10-13T00:00:00Z But dark matter particles, scientists think, can avoid all those obstacles. Huge underground search for mysterious dark matter begins 2022-07-07T04:00:00Z Dark matter also has implications for cosmology, since there may be enough dark matter to stop the expansion of the universe. College Physics for AP Courses 2015-08-12T00:00:00Z The Standard Model is silent about dark matter and even the force of gravity. 10 Years after the Higgs, Physicists Are Optimistic for More Discoveries 2022-07-05T04:00:00Z The research actually involved searching for potential interactions between neutrons and a type of theorized dark matter called “mirror matter.” NOT REAL NEWS: A look at what didn’t happen this week 2022-07-01T04:00:00Z What causes the largest mass-to-light ratio: gas and dust, dark matter, or stars that have burnt out?

As the Large Hadron Collider Revs Up, Physicists’ Hopes Soar 2022-06-13T04:00:00Z In the same way, astronomers now routinely determine the location and amount of dark matter in galaxies by measuring its gravitational effects on objects we can see. Astronomy 2016-10-13T00:00:00Z For instance, the rotational speeds of galaxies are such that, without the gravity of dark matter to hold them together, they would have long since disintegrated. Astronomers Might See Dark Matter by Staring into the Void 2022-06-08T04:00:00Z The proposal is radical in the sense that it invokes entirely new forms of matter, in fact two entirely new forms, in order to explain dark matter and other phenomena. College Physics for AP Courses 2015-08-12T00:00:00Z It leaves out the force of gravity, and it doesn’t include mysterious, invisible dark matter, which appears to outweigh ordinary matter in the universe six to one. Ten years after the Higgs, physicists face the nightmare of finding nothing else 2022-06-12T04:00:00Z Nothing showed up except the Higgs — in particular, no new particle that might explain the nature of dark matter. As the Large Hadron Collider Revs Up, Physicists’ Hopes Soar 2022-06-13T04:00:00Z And, by measuring the way that galaxies move in clusters, scientists have discovered that dark matter is also distributed among the galaxies in the clusters. Astronomy 2016-10-13T00:00:00Z The team also found—somewhat unsurprisingly—that most gamma rays from dark matter in these voids should emerge via the decay of the particles rather than their annihilation. Astronomers Might See Dark Matter by Staring into the Void 2022-06-08T04:00:00Z Lacking direct evidence of WIMPs as dark matter, why must we eliminate all other possible explanations based on the known forms of matter before we invoke their existence? College Physics for AP Courses 2015-08-12T00:00:00Z Another Wilczek prediction—the “axion”—remains unconfirmed but is a leading candidate for dark matter, the invisible substance thought to comprise the majority of mass in the universe.

Readers Respond to the December 2021 Issue 2022-04-27T04:00:00Z We’ll look next at the search for dark matter and the quest to determine its nature. Astronomy 2016-10-13T00:00:00Z Here, the “lampposts” are regions of space teeming with galaxies and galaxy clusters, which are thought to be embedded in dense clouds, or “halos,” of dark matter. Astronomers Might See Dark Matter by Staring into the Void 2022-06-08T04:00:00Z The observation implies that the stars circulate within a vast cloud of dark matter that provides the additional gravity needed to rein them in. To crack the mystery of dark matter, physicists turn to supersensitive quantum sensors 2022-04-27T04:00:00Z Since then, other physicists have suggested that axions, if they exist, have just the right properties to make up dark matter. God, Dark Matter and Falling Cats: A Conversation with 2022 Templeton Prize Winner Frank Wilczek 2022-05-11T04:00:00Z Merger models routinely incorporate simple models of dark matter distribution, which greatly improves their ability to reproduce observed properties of galactic mergers, for example, by absorbing much of the orbital energy during the collision. Readers Respond to the December 2021 Issue 2022-04-27T04:00:00Z This result, along with a variety of other experiments, leads us to conclude that the types of matter we are familiar with can make up only a tiny portion of the dark matter. Astronomy 2016-10-13T00:00:00Z Still, WIMPs remain the favored candidate for dark matter, says study co-author Nicolao Fornengo of the University of Torino in Italy. Astronomers Might See Dark Matter by Staring into the Void 2022-06-08T04:00:00Z To spot such quarry, dark matter hunters have turned to quantum sensors—a shift partly inspired by another hot field: quantum computing.
