Researchers built a high-resolution dark-matter N-body simulation, seeded with Planck cosmological parameters, tracking halo mergers from redshift 35 to 7.5 using ROCKSTAR and CONSISTENT-TREES tools. They layered a semi-analytic galaxy-formation model onto this framework to simulate gas cooling, star formation, supernova feedback and radiation, showing that overmassive black holes and compact 'little red dot' galaxies emerge naturally from these early-universe conditions without requiring exotic physics.
A new clip from the third episode of 'Dark Matter' season two, titled 'Everything Beautiful, Everything Terrible,' shows the series confronting a major plot complication that arose from its multiverse premise. The action-heavy preview suggests the show is directly grappling with the ripple effects of its characters' choices across parallel realities rather than glossing over them.
Researchers led by Teixeira, building on Khoury and Vafa's string theory work, propose that dark energy and dark matter interact and share a common origin tied to an extra 'dark dimension' far larger than other theorized hidden dimensions. In this framework, massive 'dark gravitons' leaking into this dimension could explain why the universe's measured expansion rate differs by about 9 percent depending on when it's measured, an anomaly known as the Hubble tension.
Physicists operating the LZ Dark Matter Experiment nearly a mile underground in South Dakota detected a single subatomic interaction that doesn't match any known physics signature. The team has submitted findings to Physical Review Letters, stressing they cannot yet say whether it's a dark matter signal, background noise, or something entirely new.
Apple TV confirmed that Silo season 4, which will be the show's final season, will premiere on July 9, 2027. The announcement came alongside the debut of the season 3 finale and included the release of a first trailer containing spoilers for season 3.
Physicists at the Sanford Underground Research Facility in South Dakota detected an anomalous energy signature inside a liquid xenon tank, caused by something striking a xenon nucleus and making it recoil. Researchers cannot yet identify the source of the collision, but they say it could represent the strongest physical evidence yet for dark matter, potentially a Weakly Interacting Massive Particle (WIMP) passing through Earth.
Apple TV's new action-comedy Mayday, starring Ryan Reynolds and Kenneth Branagh and directed by the Game Night team of John Francis Daley and Jonathan Goldstein, premieres September 4. Early reviews from outlets like JoBlo, Empire, and The Hollywood Reporter praise its action sequences, humor, and the leads' chemistry, with several critics noting it feels strong enough to have warranted a theatrical release.
A research team has detected an anomalous signal that current physics cannot fully explain, raising the possibility it could be evidence of dark matter or an entirely new phenomenon. The finding comes after years of dedicated searches for dark matter, a substance believed to make up much of the universe's mass but never directly observed.
Researchers on the LUX-ZEPLIN (LZ) experiment, led in part by Brown University scientists, detected a single particle interaction consistent with a WIMP dark matter candidate of at least 200 GeV/c2 mass. The signal reached only 2.6-sigma statistical significance, far below the 5-sigma threshold needed to claim discovery, but stood out because background noise in that region is unusually low.
Scientists at the LUX-ZEPLIN experiment, which uses 10 tonnes of liquid xenon buried in South Dakota's Sanford Underground Research Facility, recorded one unusual flash consistent with a WIMP particle striking a xenon nucleus. The result, described in a preprint that has not yet been peer-reviewed, is far from confirmed but has generated excitement because it could represent the long-sought direct detection of dark matter.
NASA launched the Nancy Grace Roman Space Telescope on 30 August aboard a SpaceX rocket, sending it roughly 1.5 million kilometres from Earth to begin observing the Universe. The telescope's 2.4-metre mirror, originally built for surveillance purposes and handed to NASA in 2012, was re-engineered for astronomy and paired with a 300-megapixel infrared camera capable of imaging patches of sky about 100 times larger than the Hubble Space Telescope can capture in one shot.
Researchers on the LUX-ZEPLIN experiment at South Dakota's Sanford Underground Research Facility reported a lone high-energy event in their 10-tonne liquid xenon detector, recorded sometime in 2023 or 2024, that matches the expected signature of a dark matter particle striking an atomic nucleus. The team announced the finding at a physics conference in Japan and posted details in a preprint, while cautioning that a single event is not proof.
