The universe could be filled with ultralight black holes that can’t die

Primordial black holes are hypothetical objects formed during the earliest moments of the universe. According to the models, they formed from micro-fluctuations in matter density and spacetime to become sand grain-sized mountain-massed black holes.

Astronomers observe elusive stellar light surrounding ancient quasars

MIT astronomers have observed the elusive starlight surrounding some of the earliest quasars in the universe. The distant signals, which trace back more than 13 billion years to the universe’s infancy, are revealing clues to how the very first black holes and galaxies evolved.

Collaboration identifies rare nuclear decay in long-lived potassium isotope

Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This isotope usually decays to calcium-40, but about 10% of the time it decays to argon-40.

Scientists directly measure a key reaction in neutron star binaries

An X-ray burst (XRB) is a violent explosion that occurs on the surface of a neutron star as it absorbs material from a companion star. During this absorption, increasing temperatures and densities on the surface of the neutron star ignite a cascade of thermonuclear reactions.

Attosecond core-level spectroscopy reveals real-time molecular dynamics

Chemical reactions are complex mechanisms. Many different dynamic processes are involved, affecting both the electrons and the nucleus of the present atoms. Very often, the strongly coupled electron and nuclear dynamics induce radiation-less relaxation processes known as conical intersections. Such dynamics, which are at the basis of many biological and chemical relevant functions, are extremely […]

Scientists’ research answers big question about our system’s largest planet

New discoveries about Jupiter could lead to a better understanding of Earth’s own space environment and influence a long-running scientific debate about the solar system’s largest planet.

Fusion record set for tungsten tokamak WEST

Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) measured a new record for a fusion device internally clad in tungsten, the element that could be the best fit for the commercial-scale machines required to make fusion a viable energy source for the world.

Experiment opens door for millions of qubits on one chip

Researchers from the University of Basel and the NCCR SPIN have achieved the first controllable interaction between two hole spin qubits in a conventional silicon transistor. The breakthrough opens up the possibility of integrating millions of these qubits on a single chip using mature manufacturing processes.

Eery coincidence? The constant of speed of light equals the coordinates of the Great Pyramid of Giza

Is it just an eerie coincidence that the speed of Light equals the coordinates of the Great Pyramid of Giza? The speed of light in a vacuum is 299, 792, 458 meters per second, and the geographic coordinate for the Great Pyramid of Giza is 29.9792458°N. Some say this is just one of the […]

Study investigates a nearby M-dwarf binary system

Using the Very Long Baseline Array (VLBA), astronomers have explored a nearby binary stellar system composed of two M dwarfs, known as LP 349−25AB. Results of the study, presented April 25 on the pre-print server arXiv, shed more light on the properties of this system, suggesting that one of its components may be a brown […]
