Theorists are in a frenzy over “fractons,” bizarre, but potentially useful, hypothetical particles that can only move in combination with one another ================================================================================= Your desk is made up of individual, distinct atoms, but from far away its surface appears smooth. This simple idea is at the core of all our models of the physical world. We can describe what’s happening overall without getting bogged down in the complicated interactions between every atom and electron. So when a new theoretical state of matter was discovered whose microscopic features stubbornly persist at all scales, many physicists refused to believe in its existence....

LENR Solution of the Cosmological Lithium Problem # V.I.Vysotskii1 , M.V.Vysotskyy1 , Sergio Bartalucci2 1 Taras Shevchenko National University of Kyiv, Kyiv, 01601, Ukraine 2 http://ikkem.com/iccf23/orppt/ICCF23-OA-10%20Vysotskii.pdf INFN Laboratori Nazionali di Frascati, Frascati, 00044 Italy # E-mail: vivysotskii@gmail.com, Volodymyrska Str. 64, Kyiv, 01601, Ukraine The basis of modern cosmology is the Big Bang theory. The validity of this theory is based on three main facts: a) the redshift of spectral lines of distant stars; b) the presence of cosmic microwave background radiation; c) the theory of primary Big Bang nucleosynthesis (BBN) of light H2 , He3 , He4 , Li6 and...

Experimental setup. As a beam of beryllium comes in from the left, the deuteron Trojan horse intercepts it at the target and delivers its neutron soldier. This allows the decay products of the beryllium and neutron reactions to be captured by a curved array of six detectors on the right. Credit: Hayakawa et al. There is a significant discrepancy between theoretical and observed amounts of lithium in our universe. This is known as the cosmological lithium problem, and it has plagued cosmologists for decades. Now, researchers have reduced this discrepancy by around 10%, thanks to a new experiment on...

Credit: Public Domain The cosmogony Eureka, which Edgar Allan Poe (1809-1849) published the year before his death, anticipates modern science and cosmology.1 It describes a process that is now popularly known as the ‘Big Bang’ and the expanding universe. But it also contains ideas about the unity of space and time, the mathematical equality of matter and energy, the velocity of light and a rudimentary concept of relativity, black holes (including one at the center of our Milky Way), a "pulsating" universe that renews itself eternally, and other universes in other dimensions with different laws of nature. Contrary to the...

Superconductors are highly desirable, especially when it comes to reducing energy consumption. They show quantum properties on the scale of ordinary items. This makes them exciting candidates for building computers that use quantum physics. However, qubits, the elementary units of quantum computers, are extremely sensitive. When contact electromagnetic fields, heat, and collisions with air molecules, qubits lose their quantum properties. The addition of more resilient qubits using topological superconductors can protect qubits from losing their properties. In a new study, scientists led by Kent and the STFC Rutherford Appleton Laboratory have reported about the discovery of a new rare topological...

A new electrode that could free up 20% more light from organic light-emitting diodes has been developed at the University of Michigan. It could help extend the battery life of smartphones and laptops, or make next-gen televisions and displays much more energy efficient. The approach prevents light from being trapped in the light-emitting part of an OLED, enabling OLEDs to maintain brightness while using less power. In addition, the electrode is easy to fit into existing processes for making OLED displays and light fixtures. "With our approach, you can do it all in the same vacuum chamber," said L. Jay...

This cut-away rendering of the MIT nuclear battery concept shows important components such as the instrumentation and control module, the reactor, and the power module. Credit: Massachusetts Institute of Technology ===================================================================================== We may be on the brink of a new paradigm for nuclear power, a group of nuclear specialists suggested recently in The Bridge, the journal of the National Academy of Engineering. Much as large, expensive, and centralized computers gave way to the widely distributed PCs of today, a new generation of relatively tiny and inexpensive factory-built reactors, designed for autonomous plug-and-play operation similar to plugging in an oversized battery,...

Artist’s impression of cosmic filaments: huge bridges of galaxies and dark matter connect clusters of galaxies to each other. Galaxies are funneled on corkscrew like orbits towards and into large clusters that sit at their ends. Their light appears blue-shifted when they move towards us, and red-shifted when they move away. Credit: AIP/ A. Khalatyan/ J. Fohlmeister ==================================================================================== By mapping the motion of galaxies in huge filaments that connect the cosmic web, astronomers at the Leibniz Institute for Astrophysics Potsdam (AIP), in collaboration with scientists in China and Estonia, have found that these long tendrils of galaxies spin on the...

The Universe is a large place, and there are a lot of large things in it. Not just galaxies, but groupings of galaxies, and the cosmic web that connects them all together. Scientists have just discovered what appears to be one of these groupings, and it could have serious implications for our understanding of the evolution of the Universe. It's an almost-symmetrical arc of galaxies at a distance of 9.2 billion light-years away, and, at 3.3 billion light-years across, it's one of the biggest structures ever identified. Astronomers are calling it the Giant Arc, and, if confirmed, it joins a...

Hiromitsu Takeuchi, a lecturer at the Graduate School of Science, Osaka City University, and a researcher at the Nambu Yoichiro Institute of Theoretical and Experimental Physics (NITEP), has theoretically identified the nature of a mysterious topological defect produced by the recently discovered non-equilibrium time evolution of spontaneous symmetry breaking (SSB). Since the SSB realized in this system is like the SSB that has been known to occur in isotropic superconductors and superfluid 4He, it was expected to produce topological defects with vortex-like properties in the fluid, called quantum vortices. However, the topological defect observed in this experiment has a structure...

Physicists Observe New Phase in Quantum Condensate of Light Apr 2, 2021 by Enrico de Lazaro Physicists at the University of Bonn have experimentally observed a new, previously unknown phase in the photon Bose-Einstein condensate. The Bose-Einstein condensate is a gas of atoms so dense and cold that their matter waves lose their individuality and condense into a ‘superatom wave.’ It was predicted in the 1920s by Satyendra Nath Bose and Albert Einstein and was eventually created in the lab in the 1990s at the University of Colorado Boulder, MIT and Rice University using laser cooling and evaporative cooling techniques....

Lattice Confinement Fusion NASA Detects Lattice Confinement Fusion A team of NASA researchers seeking a new energy source for deep-space exploration missions, recently revealed a method for triggering nuclear fusion in the space between the atoms of a metal solid. Their research was published in two peer-reviewed papers in the top journal in the field, Physical Review C, Volume 101 (April, 2020): “Nuclear fusion reactions in deuterated metals” and “Novel nuclear reactions observed in bremsstrahlung-irradiated deuterated metals.” Nuclear fusion is a process that produces energy when two nuclei join to form a heavier nucleus. “Scientists are interested in fusion, because...

Plutonium is generally thought of as an artificial element created by humans, primarily to make the pits of nuclear weapons, but naturally occurring plutonium can be found in ancient rocks. Plutonium 244 is the longest lived isotope of Plutonium, but it's not easy to make, and finding this specific isotope in interstellar dust grains laid down on the ocean floors tells us important things about the formation of the elements that make up the Earth.Based on this paper:60Fe and 244Pu deposited on Earth constrain the r-process yields of recent nearby supernovae A.

(NASA/CXC/UMass/Q.D. Wang; NRF/SARAO/MeerKAT) SPACE ------------------------------------------------------------------------------- The center of the Milky Way is a strange and wild place. There dwells our galactic nucleus - a supermassive black hole 4 million times the mass of the Sun, a beast named Sgr A*. It's probably the most extreme environment in our galaxy, dominated by Sgr A*'s gravitational and magnetic fields. It's also very hard to see into, even though it's only 25,800 light-years away: The region is shrouded by thick clouds of dust and gas that obscure some wavelengths of light. But if we use technology to tweak our vision into the invisible...

Structure of the new carbon network. The upper part shows schematically the linking of the carbon atoms, forming squares, hexagons, and octagons. The lower part is an image of the network, obtained with high-resolution microscopy. Credit: University of Marburg, Aalto University ================================================================================ Carbon exists in various forms. In addition to diamond and graphite, there are recently discovered forms with astonishing properties. For example graphene, with a thickness of just one atomic layer, is the thinnest known material, and its unusual properties make it an extremely exciting candidate for applications like future electronics and high-tech engineering. In graphene, each carbon atom...

The quantum world is notoriously weird. Single particles can be in two places at once, for example. Only by making an observation do we force it to 'choose'. Before an observation we can only assign probabilities to the likely outcomes. Such a picture cannot be reconciled with a smooth, continuous fabric of space-time. According to Einstein, space-time is warped by matter and energy, but quantum physics says matter and energy exist in multiple states simultaneously — they can be both here and over there. According to Einstein, space-time is like a stage that remains in place whether actors are treading...

Matter and antimatter are always created (or destroyed) in equal amounts. But there appears to be a dearth of antimatter in the universe. What happened to it?

Sailing through the smooth waters of vacuum, a photon of light moves at around 300 thousand kilometers (186 thousand miles) a second. This sets a firm limit on how quickly a whisper of information can travel anywhere in the Universe. While this law isn't likely to ever be broken, there are features of light which don't play by the same rules. Manipulating them won't hasten our ability to travel to the stars, but they could help us clear the way to a whole new class of laser technology. Physicists have been playing hard and fast with the speed limit of...

“Black dwarf supernovae”. They sound quite dramatic! And indeed, they may be the last really exciting events in the Universe.It’s too early to be sure. There could be plenty of things about astrophysics we don’t understand yet—and intelligent life may throw up surprises even in the very far future. But there’s a nice scenario here:• M. E. Caplan, Black dwarf supernova in the far future, Monthly Notices of the Royal Astronomical Society 497 (2020), 4357–4362.First, let me set the stage. What happens in the short run: say, the first 1023 years or so?For a while, galaxies will keep colliding. These...

What’s the price of an accurate clock? Entropy, a new study has revealed. Entropy — or disorder — is created every time a clock ticks. Now scientists working with a tiny clock have proven a simple relationship: The more accurate a clock runs, the more entropy it generates. "If you want your clock to be more accurate, you’ve got to pay for it,” study co-author Natalia Ares, a physicist at the University of Oxford, told Live Science. “Every time we measure time, we are increasing the universe’s entropy." As we go forward in time, the second law of thermodynamics states...
