Astrophysics team lights the way for more accurate model of the universe
Oct 20, 2020 (SPX)
The gravity associated with massive pockets of dark matter that lie between Earth and these galaxies, however, plays havoc with those galactic light signals. Gr...
Zeptoseconds: new world record in short time measurement
Oct 19, 2020 (SPX)
Now atomic physicists at Goethe University in Professor Reinhard Dorner's team have for the first time studied a process that is shorter than femtoseconds by ma...
A billion tiny pendulums could detect the universe's missing mass
Oct 15, 2020 (SPX)
According to cosmologists, all the visible material in the universe is merely floating in a vast sea of dark matter - particles that are invisible but nonethele...
Scientists find upper limit for the speed of sound
Oct 11, 2020 (SPX)
The result- about 36 km per second - is around twice as fast as the speed of sound in diamond, the hardest known material in the world. Waves, such as sound or ...
Signals from distant stars connect optical atomic clocks across Earth for the first time
Oct 09, 2020 (SPX)
The BIPM in Sevres near Paris routinely calculates the international time recommended for civil use (UTC, Coordinated Universal Time) from the comparison of ato...
The black hole always chirps twice: New clues deciphering the shape of black holes
Oct 09, 2020 (SPX)
Although colliding black holes do not produce light, astronomers can observe the detected gravitational waves - ripples in the fabric of space and time - that b...
New measurements of the solar spectrum verify Einstein's theory of General Relativity
Oct 09, 2020 (SPX)
The General Theory of Relativity, published by Albert Einstein between 1911 and 1916, introduced a new concept of space and time, by showing that massive object...
Molecular swarm rearranges surface structures atom by atom
Oct 08, 2020 (SPX)
At the same time, the surface structure of a metal influences its electronic properties. This is particularly important for the efficiency of electronic compone...
A RUDN University physicist simplified the Einstein-lovelock theory for black holes
Oct 07, 2020 (SPX)
This could help scientists study black holes in theories with quantum corrections to Einstein's equations. The work was published in the Physics Letters B journ...
Hunting for the lowest known nuclear-excited state
Oct 07, 2020 (SPX)
Using an extremely accurate detector, it was possible to detect the tiny temperature increase due to the energy released during the de-excitation of the atomic ...
UK Nobel physics laureate pays tribute to snubbed Hawking
Oct 06, 2020 (AFP)
Penrose, 89, told reporters that he had just come out of the shower when he received confirmation of the prize from the Nobel committee. "I wasn't expecting it ...
Very Large Telescope finds 6 galaxies trapped in web of black hole
Oct 01, 2020 (UPI)
The discovery, described Thursday in the journal Astronomy and Astrophysics, helps explain how supermassive black holes got so big so soon after the Big Bang. "...
Radio astronomers join moon mission to explore early universe
Sep 23, 2020 (SPX)
The universe was dark and foggy during its "dark ages," just 380,000 years after the Big Bang. There were no light-producing structures yet like stars and galax...
New approach to exotic quantum matter
Sep 23, 2020 (SPX)
Since quantum statistics is defined through the behavior of the phase of the wave function, when two identical particles are exchanged, early attempts of anyon ...
Ecologists confirm Alan Turing's theory for Australian fairy circles
Sep 23, 2020 (SPX)
Researchers from Germany, Australia and Israel undertook an in-depth fieldwork study in the remote Outback of Western Australia. They used drone technology, spa...
Remembrance of waves past: memory imprints motion on scattered waves
Sep 23, 2020 (SPX)
Scattering phenomena also appear in realms as diverse as quantum mechanics and gravitation. According to Pavel Ginzburg, professor at Tel Aviv University's Scho...
Why there is no speed limit in the superfluid universe
Sep 22, 2020 (SPX)
Helium-3 is a rare isotope of helium, in which one neutron is missing. It becomes superfluid at extremely low temperatures, enabling unusual properties such as ...
Cosmic X-rays reveal an indubitable signature of black holes
Sep 22, 2020 (SPX)
The team consisting of Mr. Srimanta Banerjee and Professor Sudip Bhattacharyya from the Tata Institute of Fundamental Research, India, and Professor Marat Gilfa...
New calculation refines comparison of matter with antimatter
Sep 18, 2020 (SPX)
Scientists first observed a slight difference in the behavior of matter and antimatter - known as a violation of "CP symmetry" - while studying the decays of su...
Large Hadron Collider upgrade to be led by Manchester scientists
Sep 14, 2020 (SPX)
CERN's High Luminosity LHC project (HL-LHC), a large international collaboration, will upgrade the LHC by increasing the number of particle collisions by a fact...
