Nowadays we know that, in our Universe, dark matter occupies about 25% of the content, compared to only 5% of the "visible" ordinary matter. In this talk, we propose that the description of dark matter would be an extension of the Standard Model—a gauge theory. We all know that in ...
Since we don't know what dark matter is, the answer is: for every possible candidate for the dark matter there is a different strategy to search for it. People build giant detectors deep underground (to get away from all the other particles streaming through the environment around us) and ...
However, dark matter is harder to study than even that because it does not come conveniently clumped into super-dense balls like stars and black holes. (That would be far too easy.) Instead, the primary theory of dark matter says that it is made of hypothetical particles called Weakly Inter...

If the new mass prediction is accurate, scientists should be able to figure out whether axions actually exist within the next few years, study team members said. Axions are also predicted by an extension of quantum chromodynamics (QCD), the theory describing the strong nuclear force, one of th...
Taking the theory of the figure. Try worrying about. Reporting to the sales manager. Visiting customers. Fixing tiger. Listen to the prophets again and answer the following questions. When does the supervisor usually deal with customers? Who will provide sales figure on a weekly basis. When do...

What is Dark Matter Made of? Keep in mind that dark matter is a theory. As telescopes got bigger and we observed more of the universe, we realized that there’s far more gravity in the universe than can be accounted for. What’s creating it? What is this strange, unseen, powerful stu...
Another theory, which is a counterpoint to WIMPs, is something called MACHO’s, or “massive astrophysical compact halo object” (you really have to love astrophysicists’ ability to come up with acronyms). This would be a regular old matter, but stuff that doesn’t emit light that we can...
Caloricwas the ”dark matter” of the early 19th century. It was a hypothetical particle that was supposed to describe heat. It was later dismissed as a theory with the emergence of thermodynamics. Source: Niklas Nielsen In the very first split seconds after the Big Bang, our Universe was ...
