Quantum vortices as black hole analogs. Researchers led by Patrik Švančara of the University of Nottingham, have used superfluid helium in order to generate quantum vortices and use them as black hole analogs. That means that the vortices twist their environment just as black holes do with their surrounding space, making possible to study some of the properties of the latter in the lab. Thanks to this technique, the team observed standing waves analogous to black hole bound states, and excitations analogous to the ringdown of a newly formed black hole, allowing them to be optimistic about what discoveries can be done in the near future. The findings have been published in Nature (30 March, 2024). https://lnkd.in/dVSaFxEC #physics #physicsnews #astrophysics #astronomy #quantumphysics #quantummechanics #generalrelativity #quantumvortices #blackhole #blackholes

An unexpected potential use of CERN's particle detectors. Researchers at Harvard University, University of Nevada and Pennsylvania State University have demonstrated that the tile calorimeter at the center of CERN's ATLAS and CMS detectors could detect the flux of high-energy supernova neutrinos. Furthermore, according to their calculations, they could also characterize the flavor of the neutrinos, and to discriminate between neutrinos and antineutrinos. The findings have been published in Physical Review Letters (8 February, 2024). https://lnkd.in/dETN8Zhb #physics #physicsnews #particlephysics #astronomy #astrophysics #neutrino #neutrinos #atlas #cms #cern #supernova #supernovae

European #XFEL reaches unmatched level in measurements of matter under extreme conditions   Scientific journal highlights corresponding publication as “Editor’s suggestion”   Researchers at European XFEL have developed an innovative method to study warm dense matter with unprecedented accuracy. This kind of matter, that exists between condensed matter and plasma #physics, can be found, for example, in #astrophysical objects or is created during inertial confinement #fusion.

Abstract: "Relativistic electron-positron plasmas are ubiquitous in extreme astrophysical environments such as black-hole and neutron-star magnetospheres, where accretion-powered jets and pulsar winds are expected to be enriched with electron-positron pairs. Their role in the dynamics of such environments is in many cases believed to be fundamental, but their behavior differs significantly from typical electron-ion plasmas due to the matter-antimatter symmetry of the charged components. So far, our experimental inability to produce large yields of positrons in quasi-neutral beams has restricted the understanding of electron-positron pair plasmas to simple numerical and analytical studies, which are rather limited. We present the first experimental results confirming the generation of high-density, quasi-neutral, relativistic electron-positron pair beams using the 440 GeV/c beam at CERN’s Super Proton Synchrotron (SPS) accelerator. Monte Carlo simulations agree well with the experimental data and show that the characteristic scales necessary for collective plasma behavior, such as the Debye length and the collisionless skin depth, are exceeded by the measured size of the produced pair beams. Our work opens up the possibility of directly probing the microphysics of pair plasmas beyond quasi-linear evolution into regimes that are challenging to simulate or measure via astronomical observations." https://lnkd.in/ewbEtPPK Laboratory realization of relativistic pair-plasma beams

Warp Speed to Reality: Faster-Than-Light Travel Now Possible?🚀🌌 Scientists have made a breakthrough in warp drive technology, once considered pure sci-fi. 👽 A new study proposes a "constant-velocity subluminal warp drive" that doesn't require #exotic #matter, instead using innovative gravitational techniques. This model aligns with Einstein's relativity, suggesting high-speed interstellar travel could be feasible without violating known physics. While still energy-intensive, this approach moves us closer to realizing warp speed travel, potentially revolutionizing space exploration. This sounds like alien technology to me 🤔 👾 🛸 Read more here: https://lnkd.in/ey-2XccN #SpaceExploration #WarpDrive #Physics #Innovation #FutureTech

A new atomic clock with unprecedented accuracy. Researchers from JILA (originally the Joint Institute for Laboratory Astrophysics) have developed the most precise and accurate atomic clock up to date, being able to lose just a second every 30000 million years. At its core, there's an extremely cold gas of strontium atoms trapped in an optical lattice, trapped in a web of lasers that significantly reduces major sources of error due to fainter interactions between atoms compared with prior designs. According to the designers, this clock is so precise that it can detect effects predicted by the general relativity at the submillimeter scale, something that could help bridge the gap between the latter and quantum mechanics. The findings will be published in Physical Review Letters. https://lnkd.in/dACxp5r5 #physics #physicsnews #atomicclock #generalrelativity #quantummechanics

⚠ This is a major breakthrough in physics and could help unite Quantum Mechanics with the Theory of General Relativity. 💡 "Gravity differs from all other known fundamental forces because it is best described as a curvature of space-time. For that reason, it remains resistant to unifications with quantum theory. Gravitational interaction is fundamentally weak and becomes prominent only at macroscopic scales. This means, we do not know what happens to gravity in the microscopic regime where quantum effects dominate and whether quantum coherent effects of gravity become apparent. Levitated mechanical systems of mesoscopic size offer a probe of gravity, while still allowing quantum control over their motional state. This regime opens the possibility of table-top testing of quantum superposition and entanglement in gravitating systems." #physics #quantumphysics #relativity #quantumgravity

🔆 We are working to prove that there is no vacuum in space throughout the universe and that planets and galaxies swim in an invisible cosmic fluid, full of energy, essentially made up of Higgs bosons and that we can harness it and convert it into mechanical or electrical energy using the reverse energy engine (dark energy motor). 🔆 Our clocks record a different second depending on the gravitational potential due to the impulse dilation (the dilation of transfer of momentum), there is neither time dilation nor length contraction, there is only impulse dilation. ⚜ This has been proven theoretically in a new theory of gravitation called "cosmic depression theory" 🔆 Become Part of Our Community & benefit from our project forever 🔆 Add your logo or photo and your URL, #forever, to our “Golden Partners” list, and benefit from the best visibility on all our current and future websites forever. ⚜ The list of our golden partners will be closed immediately after the manufacture of the first prototype of the dark energy engine and the experiments to determine the shortest reference second within our solar system are completed. https://lnkd.in/eh7_T6jn #science #innovation #space #energy #astrophysics #physics #research #technology #MIT #Harvard #CERN #Nasa #JPL #laboratory #Renewables #climatechange

A summary that keeps hitting records across Physics Departments since 2017 as Most Read Status. A journey that still continues till 2024 off and on with more confirmations! A He-4 Nucleus Discovery over 2007-2010 and journey of 2008-2017 modeling, satisfying 6 known constraints, discovering 3 new constraints, calculating mass in 3 parity ways using the same quanta of Yukawa, the first Noble Laureate for the Strong Force, not knowing till 2017, showing evidence of gravity and after decades finding it to be an Alpha Particle but not taught! The CCP Packing for He Nucleus as discovered in 2010 is confirmed in experiments for He as molecules! Both should have the same fractal principle! https://lnkd.in/gHfnw4ZJ https://lnkd.in/gbaJg3CC #physics #mathematics #nasa #universe #quantummechanics #gravity #liealgebra #cartanalgebra #roots #galieolisgroups #splittingfield #relativity #generalgravity #specialreleativity #iits #stanford #mit #iits #harvard #universe #qcd #strongforce #nucleus #gravity #moleucles #crystals #packing #liealgebra #su(3) #ccp #cartanalgebra #liegroup
