Dark matter puzzle depends in part on whether our galaxy is an “outlier”

Twenty years ago, astronomers couldn’t find enough satellite galaxies orbiting the Milky Way. Now there seem to be too many. Some information seems to be missing. A possible solution is that many of these galaxies are dwarfs formed by dark matter: Most cosmologists believe that dark-matter particles are “cold,” meaning that they move slowly. Because Read More…

Dark matter detection claim takes a hit

From ScienceDaily: Astrophysical evidence suggests that the universe contains a large amount of non-luminous dark matter, yet no definite signal of it has been observed despite concerted efforts by many experimental groups. One exception to this is the long-debated claim by the DArk MAtter (DAMA) collaboration, which has reported positive observations of dark matter in Read More…

We’re not even sure what dark matter IS

A helpful list of the 11 biggest questions about dark matter starts with this: Originally, some scientists conjectured that the missing mass in the universe was made up of small faint stars and black holes, though detailed observations have not turned up nearly enough such objects to account for dark matter’s influence, as physicist Don Read More…

For better results, search for dark matter should unite particle physics and astronomy, says physicist

Dark matter was first theorized a century ago and yet “ super-sensitive underground labs that can detect a particle just one-trillionth of one-trillionth of a square centimeter” haven’t found it. Some now think that the problem is that two different approaches to the search are in conflict: There are two methods that physicists use to Read More…

Discover: Even the best dark matter theories “are crumbling”

Because the best theories have not identified dark matter after decades: Having been fooled once, scientists have to ask: Is dark matter the new ether? For decades, a few rogue scientists have stood hopefully at the edge of respectability, offering their theory called Modified Newtonian Dynamics, or MOND. Essentially, it says that physics doesn’t work Read More…

When research collides: Modified gravity vs. dark matter

Modified gravity is a hypothesis (1983) that attempts to account for the gravitational pull that is otherwise attributed to dark matter (which has never been identified). From Sabine Hossenfelder, author of Lost in Math: How Beauty Leads Physics Astray, at : Which one is right? We still don’t know, though astrophysicists have been on the case Read More…

Researcher: The search for dark matter has become a “quagmire of confirmation bias”

From science writer Bruce Dorminey at Forbes: Time may be running out on the search for the cosmos’ exotic dark matter. Decades after the first searches for dark matter’s hypothetical exotic particle counterparts, researchers are mostly at a loss to explain why there still has been no direct detection. That is, one that could explain Read More…

He who knows something gains respect. He who knows everything …

Well, the Canadian Science Writers’ Association conference at Science North in Sudbury wrapped up yesterday, and today I got a chance to tour SNOLAB, the underground neutrino detector in the active Creighton Mine, which is currently retooling for SNO Plus, the hunt for dark matter. Just for now: The Solar Neutrino Observatory (SNO) Lab is Read More…
