The world’s second-fastest supercomputer, Frontier, has achieved a groundbreaking feat: creating the most intricate computer simulation of the universe to date. This simulation, utilizing the Hardware/Hybrid Accelerated Cosmology Code (HACC), pushes the boundaries of cosmological hydrodynamics research, offering unprecedented insights into the universe’s evolution and the nature of dark matter and dark energy.
Analysis of a massive dataset from the Dark Energy Spectroscopic Instrument (DESI) confirms Einstein’s theory of general relativity on a cosmic scale, bolstering the Lambda Cold Dark Matter model and challenging alternative theories of gravity. The findings, based on nearly 6 million galaxies and quasars, offer a powerful new test of our understanding of the universe’s expansion and structure.
The European Space Agency’s Euclid telescope has released its first glimpse of a massive 3D map of the universe, showcasing 14 million galaxies in a breathtaking mosaic. This is just the beginning of Euclid’s mission to map one-third of the night sky and unravel the mysteries of dark matter and dark energy.
A new study suggests that tiny, primordial black holes, formed shortly after the Big Bang, could be flying through our solar system every decade. These black holes, while minuscule, could generate detectable gravitational disturbances in the orbits of planets. This intriguing possibility could shed light on the mystery of dark matter, the invisible substance that makes up a significant portion of the universe.
Recent observations have thrown the well-established standard model of cosmology into question, leading to heated debates about the nature of dark energy and dark matter. The Hubble tension, S8 tension, and unexpected properties of early galaxies have challenged the model’s fundamental assumptions. While more data is needed to resolve these issues, the future holds exciting possibilities for a paradigm shift in our understanding of the universe.
A new theory suggests that dark matter, the mysterious substance that makes up most of the universe’s mass, could be composed of primordial black holes formed during a transition from the universe’s last contraction to its current expansion phase. This ‘bouncing’ universe theory challenges the traditional Big Bang model and offers a testable hypothesis for the origin of dark matter.
From the expansion of the universe to the spinning of galaxies, motion is a fundamental aspect of the cosmos. This article explores the reasons behind this constant movement, including the Big Bang, angular momentum, and the mysterious influence of dark matter.
Scientists have been trying to understand how supermassive black holes form through mergers of smaller black holes. However, simulations have shown that these black holes get stuck in an eternal orbit before merging. A new study suggests that self-interacting dark matter could be the missing ingredient, providing the energy dissipation necessary for the final merger. This discovery not only resolves the ‘final parsec problem’ but also offers insights into the nature of dark matter.
Dark matter, a mysterious component of the universe that makes up about 85% of its total mass, has eluded detection despite decades of research. However, new theoretical research suggests that waves in an ocean of dark matter could generate detectable radio waves that would allow us to finally find this elusive component of the universe. The study, published in the preprint server arXiv, explores models of ultralight dark matter that interacts extremely rarely with normal matter. When this dark matter interacts with plasma waves in Earth’s ionosphere, it could produce a resonance that amplifies the interaction and produces radiation in the form of radio waves. Using a carefully tuned radio antenna, scientists may be able to detect these radio waves and finally study one of the most mysterious elements in the universe right on our cosmic doorstep.
Apple TV+ is adding a thrilling new lineup to its streaming library in June, including the highly anticipated legal drama “Presumed Innocent” starring Jake Gyllenhaal, the heartwarming drama “Fancy Dance” featuring Academy Award-nominated actress Lily Gladstone, and the exciting sci-fi series “Dark Matter” based on the novel by Blake Crouch. These additions join a growing collection of award-winning movies and original shows that make Apple TV+ a must-have for entertainment enthusiasts.
