Gizmodo హైలైట్ చేసిన ఒక పెద్ద అధ్యయనం ప్రకారం, విశ్వంలోని అత్యంత పెద్ద నిర్మాణాలపై చేసిన పరిశీలనలు ఇప్పటికీ న్యూటన్ మరియు ఐన్‌స్టీన్ గురుత్వాకర్షణతో సరిపోతున్నాయి, అందువల్ల కేవలం మార్పుచేసిన గురుత్వమే బ్రహ్మాండ వ్యత్యాసాలను వివరించగలదనే వాదన బలహీనమైంది.

Universe Today యొక్క కొత్త explainer Cherenkov radiation వెనుక ఉన్న భౌతికశాస్త్రాన్ని ఒక సాదాసీదా ప్రశ్నపై కేంద్రీకరిస్తుంది: శూన్యంలో కంటే కాంతి పదార్థంలో ఎందుకు నెమ్మదిగా ప్రయాణిస్తుంది?

A new Physical Review Letters study led by UC Riverside physicist Hai-Bo Yu argues that self-interacting dark matter could account for three long-running astrophysical puzzles across very different environments.

A new explainer revisits one of physics’ strangest asymmetries: the weak nuclear force only interacts with left-handed particles, a quirk that helps make radioactive decay, fusion, and stars possible.

A fresh retelling of Ettore Majorana's 1937 idea is drawing attention to one of modern physics' most persistent questions: whether neutrinos could be particles that are also their own antiparticles.

Physicist John Pendry, long known for the invisibility cloak, is now using metamaterial ideas to probe more ambitious territory, including materials that could simulate black-hole-like physics.

Two highly precise hydrogen experiments now agree with the smaller proton measurement that once shocked physics, strengthening the case that the particle’s radius is about 0.84 femtometres.

After years of anomalies and speculation, recent null results have pushed many physicists to conclude that the electron-volt sterile neutrino likely does not exist.

The Super Cryogenic Dark Matter Search experiment at SNOLAB has reached its ultra-cold operating temperature, allowing detectors to begin probing a new region of possible light dark matter signals.

After decades of stalled progress, researchers believe new mathematical tools are beginning to explain how the force that binds atomic nuclei together produces the massive particles that make up visible matter.

A reported world first in bringing the rotation of a silica nanorotor to its quantum ground state points to a new level of control over motion at the nanoscale.

A palm-sized magnet now rivals the strength of room-sized superconducting behemoths, promising cheaper MRI machines and particle accelerators.

Physicists mapped a telltale superconducting dome in nickelate crystals, a hallmark of unconventional high-temperature superconductivity previously seen only in copper-based materials.

Physicists have discovered a 'superconducting dome' in thin nickelate films that suggests a pathway to high-temperature superconductivity, one of the most sought-after goals in condensed matter physics.

Researchers have discovered that subtly adjusting the ratio of tellurium and selenium in ultra-thin films can trigger a topological superconducting state critical for stable quantum computers. The breakthrough offers a more practical manufacturing route for next-generation quantum devices.

Researchers at Norway's NTNU have identified niobium-rhenium alloy as a promising triplet superconductor, a material capable of transmitting both electrical and spin currents with zero resistance. If confirmed, this discovery could pave the way for ultra-fast quantum computers that operate on almost no power.

An international team of physicists has successfully read information stored in Majorana qubits for the first time, using a quantum capacitance technique to measure the hidden states of these topologically protected quantum particles. The advance, published in Nature, marks a critical step toward fault-tolerant quantum computers.

Neuromorphic computers modeled after the human brain have demonstrated a surprising ability to solve the complex differential equations that power physics simulations.
