26. Juni 2024 · matter, material substance that constitutes the observable universe and, together with energy, forms the basis of all objective phenomena. At the most fundamental level, matter is composed of elementary particles known as quarks and leptons (the class of elementary particles that includes electrons ). Quarks combine into protons and neutrons ...
17. Juni 2024 · Scientists have made many guesses for what dark matter could be, ranging from unknown particles to extra dimensions. But Hawking’s black holes theory has only lately come into play. “People ...
Vor 2 Tagen · The matter in the universe is around 84.5% cold dark matter and 15.5% "ordinary" matter. Since the start of the matter-dominated era, dark matter has gradually been gathering in huge spread-out (diffuse) filaments under the effects of gravity. Ordinary matter eventually gathers together faster than it would otherwise do, because of the presence of these concentrations of dark matter. It is ...

26. Juni 2024 · Dark Matter Episode 9 finally brought some closure to the saga of the many Jasons, though not all of them got what they wanted by the season's finale.. The Apple TV+ series follows Joel Edgerton's Jason Dessen on a mind-bending sci-fi adventure as he tries to make his way back to the universe that he was banished from, largely adapting the novel of the same name (read more about the Dark ...
17. Juni 2024 · Dark matter is an issue that has confounded science since the term was coined in the 1930s, a reference to unseen matter that holds the universe together and causes it to behave the way it does. Astronomers confirmed the existence of dark matter in the 1970s, when they observed stars orbiting at the edges of spiral galaxies.
13. Juni 2024 · Second, I have investigated the formation of primordial black hole dark matter in a general model for inflation with multiple scalar fields. I have identified the space of models that can generate primordial black holes while remaining in compliance with observational constraints using a Markov Chain Monte Carlo, and also showed that future gravitational wave observatories will be able to ...
