How quantum computers can be validated when solving unsolvable problems
Sep 25, 2025 (SPX)
A team at Swinburne University of Technology has developed new methods to validate outcomes from a class of quantum computers called Gaussian Boson Samplers (GB...
Black hole merger provides strongest evidence yet for Hawking area law
Sep 19, 2025 (SPX)
"This specific collision involved two black holes that looked pretty much identical to the first two we saw," said Maximiliano Isi, assistant professor at Colum...
Ten Years Later, LIGO is a Black-Hole Hunting Machine
Sep 19, 2025 (SPX)
The historic discovery meant that researchers could now sense the universe through three different means. Light waves, such as X-rays, optical, radio, and other...
Gravitational wave provides strongest test yet of Hawking and Kerr black hole theories
Sep 19, 2025 (SPX)
The event was detected by LIGO in the United States, with supporting observations from Virgo in Italy and KAGRA in Japan. Researchers determined that the merger...
Mysterious 'red dots' in early universe may be 'black hole star' atmospheres
Sep 17, 2025 (SPX)
Using the first datasets released by the telescope in 2022, an international team of scientists including Penn State researchers discovered mysterious "little r...
Reconsidering the cosmological constant
Sep 17, 2025 (SPX)
A new paper published in Physical Review D in September, by Frieman and Anowar Shajib, a NASA Hubble Fellowship Program Einstein Fellow in Astronomy and Astroph...
Mapping the Universe faster without sacrificing precision
Sep 17, 2025 (SPX)
To meet the challenge posed by rapidly growing datasets from surveys like DESI and Euclid, researchers from INAF, the University of Parma, and the University of...
Black hole merger delivers strongest confirmation yet of Einstein and Hawking predictions
Sep 11, 2025 (SPX)
The newly measured gravitational waves came from a collision that formed a black hole weighing 63 times the mass of the Sun and spinning at 100 revolutions per ...
Black hole explosion may soon reveal origins of matter in the universe
Sep 11, 2025 (SPX)
Such an explosion would strongly suggest the existence of primordial black holes (PBHs), theoretical objects formed in the first second after the Big Bang. Unli...
New particle detector passes the 'standard candle' test
Sep 07, 2025 (SPX)
The sPHENIX detector is the newest experiment at Brookhaven National Laboratory's Relativistic Heavy Ion Collider (RHIC) and is designed to precisely measure pr...
New fabrication method expands material options for quantum devices
Sep 07, 2025 (SPX)
The study, published in Applied Physics Letters and selected as a "Featured" article, addresses a major obstacle: many superconductors, including transition met...
Geometry of electrons uncovered inside quantum materials
Sep 05, 2025 (SPX)
Quantum materials, which underpin next-generation computing and superconductivity, are defined by microscopic behaviors of electrons and atoms. While the 20th c...
A Sharper Image of the Early Universe
Sep 03, 2025 (SPX)
The MINERVA program, co-led by a Tufts astronomer, will give researchers an even better view than before of the early universe by using instruments on the Webb ...
Magnetic fields in the young universe revealed as incredibly faint
Sep 03, 2025 (SPX)
The conclusions come from a collaboration led by SISSA (International School for Advanced Studies, Trieste), working with teams from Hertfordshire, Cambridge, N...
Real-time tracking of atomic nucleus magnetism achieved in quantum experiment
Sep 03, 2025 (SPX)
An STM uses an ultrasharp needle to detect single atoms by sensing their electrons. Both atomic nuclei and their surrounding electrons carry a property called s...
New spectroscopy method reveals hidden atomic transitions in samarium
Aug 26, 2025 (SPX)
Understanding atomic structure is central to describing matter and designing experiments that probe its fundamental behavior. Yet for many rare earth and actini...
What came before the Big Bang remains a mystery but new tools may help
Aug 21, 2025 (SPX)
Einstein's general relativity describes gravity, but when applied to the earliest universe or black hole singularities, the equations break down. Cosmologists u...
New model shows how collapsing matter and voids shape cosmic evolution
Aug 20, 2025 (SPX)
Dr Leonardo Giani and colleagues used data from the Dark Energy Spectroscopic Instrument (DESI), which measures the structure of the universe across distances o...
Early galaxies - or something else? Mizzou scientists uncover mysterious objects in the universe
Aug 13, 2025 (SPX)
"These mysterious objects are candidate galaxies in the early universe, meaning they could be very early galaxies," said Haojing Yan, an astronomy professor in ...
Origins of giant black holes linked to first stars and early universe light bursts
Aug 13, 2025 (SPX)
Tan's "Pop III.1" framework proposes that these black holes originated from the first generation of stars - massive "Population III.1" stars - whose growth was ...
