Researchers validate theory that neutrinos shape the universe
Dec 03, 2020 (SPX)
But an international research team including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) Principal Investigator Naoki Yoshi...
A hint of new physics in polarized radiation from the early Universe
Nov 26, 2020 (SPX)
The laws of physics governing the Universe are thought not to change when flipped around in a mirror. For example, electromagnetism works the same regardless of...
Scientists make sound-waves from a quantum vacuum at the Black Hole laboratory
Nov 24, 2020 (SPX)
The Unruh effect combines quantum physics and the theory of relativity. So far it has not been possible to measure or observe it, but now new research from a te...
A new beat in quantum matter
Nov 24, 2020 (SPX)
In general, the motion of particles is affected by the presence of forces, such as those generated by electromagnetic fields. In certain crystals, emergent fiel...
NASA's Roman Space Telescope to Uncover Echoes of the Universe's Creation
Nov 19, 2020 (SPX)
Sound waves from the nascent universe, called baryon acoustic oscillations (BAOs), left their imprint on the cosmos by influencing galaxy distribution. Research...
Understanding astrophysics with laser-accelerated protons
Nov 18, 2020 (SPX)
An international research team from the GSI Helmholtzzentrum fur Schwerionenforschung and the Helmholtz Institute Jena, a branch of GSI, in collaboration with t...
Quantifying quantumness: A mathematical project 'of immense beauty'
Nov 18, 2020 (SPX)
The boundary between the classical and quantum realms has always been of great interest. Research reported in AVS Quantum Science, by AIP Publishing, considers ...
Advanced atomic clock makes a better dark matter detector
Nov 16, 2020 (SPX)
Older atomic clocks operating at microwave frequencies have hunted for dark matter before, but this is the first time a newer clock, operating at higher optical...
Black hole or no black hole: On the outcome of neutron star collisions
Nov 11, 2020 (SPX)
These properties will be studied more precisely at the future FAIR facility. The results have now been published in Physical Review Letters. With the award of t...
The universe is getting hot, hot, hot, a new study suggests
Nov 11, 2020 (SPX)
"Our new measurement provides a direct confirmation of the seminal work by Jim Peebles - the 2019 Nobel Laureate in Physics - who laid out the theory of how the...
No matter the size of a nuclear party, some protons and neutrons will pair up and dance
Nov 10, 2020 (SPX)
The environment within the nucleus of a single atom seems similar, with protons and neutrons also dancing about. But because the nucleus is such a compact space...
Final dance of unequal black hole partners
Nov 09, 2020 (SPX)
Physicists began using supercomputers to obtain solutions to this famously hard problem back in the 1960s. In 2000, with no solutions in sight, Kip Thorne, 2018...
New black hole merger simulations could help power next-gen gravitational wave detectors
Nov 09, 2020 (SPX)
As scientists develop more advanced detectors, such as the Laser Interferometer Space Antenna (LISA), they will need more sophisticated simulations to compare t...
RUDN University physicist developed software solution to measure the black holes stability
Nov 06, 2020 (SPX)
The existence of black holes was first predicted by Einstein's general theory of relativity. These objects have so strong gravitational pull that nothing, not e...
Scientists work to shed light on Standard Model of particle physics
Nov 06, 2020 (SPX)
Argonne scientists upgraded the measurement system, which uses an advanced communication scheme and new magnetic field probes and electronics to map the field t...
Measuring the expansion of the universe: Researchers focus on velocity
Nov 06, 2020 (SPX)
The researchers at the Cosmic Dawn Center found that the measurements of velocity used for determining the expansion rate of the Universe may not be reliable. A...
A distant quasar as a cosmic clock
Nov 06, 2020 (SPX)
Our early universe, starting just a few million years after the Big Bang, was a dark place. Space was filled with clouds of neutral hydrogen, but there were no ...
Timekeeping theory combines quantum clocks and Einstein's relativity
Oct 27, 2020 (SPX)
Research describing the effect shows that superposition--the ability of an atom to exist in more than one state at the same time--leads to a correction in atomi...
Einstein's Theory of Relativity, Critical For GPS, Seen In Distant Stars
Oct 23, 2020 (SPX)
The answer is an effect from Einstein's General Theory of Relativity called the "gravitational redshift," where light is shifted to redder colors because of gra...
Atomic clocks experience the quantum phenomenon called superposition
Oct 23, 2020 (UPI)
Superposition describes the ability of an atom to simultaneously exist in multiple states. In a new study, published Friday in the journal Nature, scientists th...
