Did gravitational wave detector find dark matter?
When an astronomical observatory detected two black holes colliding in deep space, scientists celebrated confirmation of Einstein's prediction of gravitational waves. A team of astrophysicists wondered something else: Had the experiment found the "Dark matter" that makes up most of the mass of the universe? Ref. Source 3o.
Sci-fi aside, this last article is really cool. If we are able to better study anti-matter then we can further develop our theory of physics and what's around us. The Standard Model predicts it should be there and should behave a certain way, but until we can prove that it does, we can't move forward and take advantage of some of the other things the Standard Model predicts. If anti-matter didn't exist (Which we are pretty sure it does), or if it didn't behave like we expect (Which they are exploring now according to this article), then we have to come up with new physics, which is fine, it won't change how we live day to day, but either way we should be able to open up more discoveries in the future.
Flashes of light on dark matter. A web that passes through infinite intergalactic spaces, a dense cosmic forest illuminated by very distant lights and a huge enigma to solve. These are the picturesque ingredients of a scientific research that adds an important element for understanding one of the fundamental components of our Universe: dark matter. Source 5k.
Unprecedentedly wide and sharp dark matter map. A research team released an unprecedentedly wide and sharp dark matter map based on the newly obtained imaging data by Hyper Suprime-Cam on the Subaru Telescope. The dark matter distribution is estimated by the weak gravitational lensing technique. The team found indications that the number of dark matter halos could be inconsistent with what the simplest cosmological model suggests. This could be a new clue to understanding why the expansion of the universe is accelerating. Source 7f.
Dark matter might not be interactive after all. Astronomers are back in the dark about what dark matter might be, after new observations showed the mysterious substance may not be interacting with forces other than gravity after all. Source 2l.
