The author of a disaster novel couldn’t have dreamed it up any better: On a Friday, the thirteenth of all days, the potentially dangerous asteroid (99942) Apophis will come extremely close to humanity. Go to Source In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light—rapidly oscillating electromagnetic waves—which can be picked up by an antenna. To honor his groundbreaking work, the unit of frequency was named “Hertz” in 1930. Hertz’s findings were later used by Guglielmo Marconi (Nobel Prize in […] A large international team of physicists working on the BES III collaboration has announced possible physical evidence of glueballs. In their study, published in the journal Physical Review Letters, the group analyzed decaying particles in a particle collider and uncovered what they believe to be evidence of glueballs. Go to Source Glasses and gels are two different types of solid materials that are commonly used in a wide range of settings. Despite their markedly different compositions, these distinct materials share some similar properties, for instance, they exhibit rigidity without a translational order and a slow transformation over time. Go to Source A team of researchers from the 5th Institute of Physics at the University of Stuttgart is making important progress in the field of quantum simulation and quantum computing based on Rydberg atoms by overcoming a fundamental limitation: the limited lifetime of Rydberg atoms. Circular Rydberg states are showing enormous potential for overcoming this limitation. Go […] Inside a tunnel system carved out of the solid limestone bedrock in the desert of Egypt, there are 24 granite boxes made of precision shaped Aswan granite. These massive ‘sarcophagi’ remain a profound mystery for scholars who are unsure as to what their true purpose was. The sarcophagi range in weight between 50 and […] Using the Indian Astronomical Observatory (IAO) and ESA’s Gaia satellite, astronomers have explored a galactic globular cluster known as NGC 2419. Results of the study, published April 29 on the preprint server arXiv, shed more light on the properties of this cluster and its stellar content. Go to Source Boeing’s first astronaut launch is off until late next week because of a bad valve in the rocket that needs to be replaced. Go to Source All around the globe, we can find numerous ancient sites that completely challenge mainstream scholars. From ancient monuments to cities in ruins, numerous archaeological sites have proven to be shrouded in mystery. In this article, I’ll take you on a journey around the globe, where we will explore five ancient cities whose origin […] Proton-lithium interactions model lays the foundation for unlocking the secrets of stellar reactionsThe reactions between protons and lithium isotopes, especially lithium-6, are pivotal for several domains ranging from nuclear energy applications to astrophysics. The detailed understanding of these interactions aids in improving models for neutron generation and sheds light on cosmic nucleosynthesis processes. Traditional models have struggled to accurately describe these complex interactions, particularly due to the […] Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein’s General Theory of Relativity, published in 1915, an entirely classical theory. This description sets gravity apart from the other three forces—strong, weak, and electromagnetism—all described by quantum fields. Therefore, any attempt to unify the four forces […] Distant galaxies, interacting galaxies, whose shape has been forged by the mutual gravitational influence, but also galaxies forming groups and clusters, kept together by gravity—they are the protagonists of three new images released by the VLT Survey Telescope (VST). Go to Source The first crewed launch of Boeing’s Starliner spaceship will have to wait until at least Friday to give ground teams time to analyze a malfunctioning rocket valve, pushing back a high-stakes test trip to the International Space Station. Go to Source Billionaire Jared Issacman, who flew to space once with SpaceX, is already set for launch No. 2 in early summer. Go to Source |
