The Standard Model is a remarkably successful but incomplete theory. Supersymmetry (SUSY) offers an elegant solution to the Standard Model’s limitations, extending it to give each particle a heavy “superpartner” with different spin properties (an important quantum number distinguishing matter particles from force particles and the Higgs boson). For example, sleptons are the spin 0 superpartners of spin 1/2 electrons, muons and tau leptons, while charginos and neutralinos are the spin 1/2 counterparts of the spin 0 Higgs bosons (SUSY postulates a total of five Higgs bosons) and spin 1 gauge bosons.

If these superpartners exist and are not too massive, they will be produced at CERN’s Large Hadron Collider (LHC) and could be hiding in data collected by the ATLAS detector. However, unlike most processes at the LHC, which are governed by strong force interactions, these superpartners would be created through the much weaker electroweak interaction, thus lowering their production rates. Further, most of these new SUSY particles are expected to be unstable. Physicists can only search for them by tracing their decay products—typically into a known Standard Model particle and the lightest supersymmetric particle (LSP), which could be stable and non-interacting, thus forming a natural dark matter candidate.

On 20 May, 2019, at the Large Hadron Collider Physics (LHCP) conference in Puebla, Mexico, and at the SUSY2019 conference in Corpus Christi, U.S., the ATLAS Collaboration presented numerous new searches for SUSY based on the full LHC Run 2 dataset (taken between 2015 and 2018), including two particularly challenging searches for electroweak SUSY. Both searches target particles that are produced at extremely low rates at the LHC, and decay into Standard Model particles that are themselves difficult to reconstruct. The large amount of data successfully collected by ATLAS in Run 2 provides a unique opportunity to explore these scenarios with new analysis techniques.

Essentially if you can enginneer a planet to a galaxy you could eventually get to a universe level of enginneering which may be needed if the universe keeps expanding. You could control the great forces of the universe to keep it stable so that it will not die out or collapse into a singularity. They say many things that gravity in the begginning kept the universe stable with dark matter that keeps things expanding other claims say that basically the universe could colapse into a single point that our universe may be a jet of another universe. Others say we live in essentially a bubble surrounded by other universes. I think though if we can reverse engineer a universe we can control our own. This would prevent our own universe from dying out or even the sun from dying out. There have been minor experiments of small universes made in the lab this could explain our own universe. But essentially we could have a perfect universe where nothing dies out or collapses into a single point in theory. Essentially an artificial universe where all the forces are controlled.

Physicists have spotted the highest-energy light ever seen. It emanated from the roiling remains left behind when a star exploded.

This light made its way to Earth from the Crab Nebula, a remnant of a stellar explosion, or supernova, about 6,500 light-years away in the Milky Way. The Tibet AS-gamma experiment caught multiple particles of light — or photons — from the nebula with energies higher than 100 trillion electron volts, researchers report in a study accepted in Physical Review Letters. Visible light, for comparison, has just a few electron volts of energy.“This energy regime has not been accessible before,” says astrophysicist Petra Huentemeyer of Michigan Technological University in Houghton, who was not involved with the research. For physicists who study this high-energy light, known as gamma rays, “it’s an exciting time,” she says.

Holographic quantum matter exhibits an intriguing connection between quantum black holes and more conventional (albeit strongly interacting) quantum many-body systems. This connection is manifested in the study of their thermodynamics, statistical mechanics and many-body quantum chaos. In this Review, we discuss these connections, focusing on the most promising example of holographic quantum systems to date – the family of Sachdev–Ye–Kitaev (SYK) models. The SYK models are simple quantum mechanical models that have the potential to holographically realize quantum black holes. We examine various proposals for the experimental realizations of SYK models, including ultracold gases, graphene flakes, semiconductor quantum wires and 3D topological insulators. These approaches offer the exciting prospect of accessing black hole physics and thus addressing many important questions regarding quantum gravity in the laboratory.

From the synapses that connect billions of neurons in the brain to the filaments of dark matter that link galactic superclusters, there’s a fractal reiteration across the magnitude of scales akin to the Mandelbrot fractal set. The mathematics behind the Mandelbrot set, which is derived from a very simple underlying formula, makes me think that its intricate fractal chaos and stunningly beautiful design can’t help but leave a feeling that there’s something larger than life going on here, that you are staring right at some ineffable cosmic mystery. https://www.ecstadelic.net/top-stories/ubiquity-of-patterns-in-nature #patterns #fractals #fractality #SyntellectHypothesis #FiveParadigms #MindsEvolution #FractalPatterns #EmergentPatterns #AsAboveSoBelow #UbiquitousPatterns #FractalGeometry #SacredGeometry #MandelbrotSet #MTheory #MultiFractality

In Nature, we find patterns, designs and structures from the most minuscule particles, to expressions of life discernible by human eyes, to the greater cosmos. These inevitably follow geometrical archetypes, platonic solids, some call it sacred geometry, which reveal to us the essence of each form and its vibrational resonances. They are also symbolic of the underlying holistic principle of inseparability of the part and the whole.

It is this principle of oneness underlying all geometry that permeates the architecture of all form in its myriad diversity. This principle of interconnectedness, inseparability and unity provides us with a continuous reminder of our relationship to the whole, a blueprint for the mind to contemplate the sacred foundation of all things created.

Russia’s beleaguered space science program is hoping for a rare triumph this month. Spektr-RG, an x-ray satellite to be launched on 21 June from Kazakhstan, aims to map all of the estimated 100,000 galaxy clusters that can be seen across the universe. Containing as many as 1000 galaxies and the mass of 1 million billion suns, the clusters are the largest structures bound by gravity in the universe. Surveying them should shed light on the evolution of the universe and the nature of the dark energy that is accelerating its expansion.

Spektr-RG x-ray mission will be nation’s only space observatory.
