 Nothing keeps time just like the beating heart of an atom. But even the crisp tick-tock of a vibrating nucleus is restricted by uncertainties imposed by the laws of quantum physics. Several years ago, researchers from MIT and therefore the University of Belgrade in Serbia proposed that quantum entanglement could push clocks beyond this blurry boundary. Now, we've got a symptom of concept within the type of experiment. Physicists connected together with a cloud of ytterbium-171 atoms with streams of photons reflected from a surrounding hall of mirrors and measured the timing of their tiny wiggles. Their results show that entangling atoms during this way could speed up the time-measuring process of atomic nuclei clocks, making them more precise than ever. in theory, a clock supported this new approach would lose just 100 milliseconds since the dawn of your time itself. Similar to other cutting-edge clocks supported by the nuclei of atoms of cesium and thorium, a time during this rea...

 The matter is what makes up the Universe, but what makes up matter? This question has long been tricky for people who consider it – especially for the physicists. Reflecting recent trends in physics, my colleague Jeffrey Eischen and that I have described an updated thanks to giving some thought to the matter. We propose that matter isn't made from particles or waves, as was long thought, but – more fundamentally – that matter is created of fragments of energy. From five to 1 The ancient Greeks conceived of 5 building blocks of matter – from bottom to top: earth, water, air, fire, and aether. Aether was the matter that filled the heavens and explained the rotation of the celebs, as observed from the planet viewpoint. These were the primary most elementary elements from which one could build up a world. Their conceptions of the physical elements didn't change dramatically for nearly 2,000 years. Then, about 300 years ago, Sir mathematician introduced the concept that every one m...

 Physicists have spotted the Higgs boson performing a brand new trick, but one that brings us no closer to understanding the workings of fundamental particles. The Higgs boson, discovered at the CERN high energy physics laboratory near Geneva, Switzerland, in 2012, is that the particle that offers all other fundamental particles mass, in keeping with the quality model of high-energy physics. However, despite the work of thousands of researchers around the world, nobody has been ready to determine exactly how it does that or why some particles are more massive than others. The only thanks to trying and solve that problem is by observing how the Higgs interacts with other particles using the massive Hadron Collider (LHC). For the primary time, both of the most important groups that use it – the CMS and ATLAS collaborations – have observed the Higgs decaying into two muons, a kind of particle we've never directly seen it interact with before. Members of the collaborations presented th...

 For the primary time ever, physicists at the world’s largest particle accelerator have observed differences within the decay of particles and antiparticles containing a basic building block of matter, called the quark. The finding could help explain the mystery of why matter exists in the least. "It's a historic milestone," said Sheldon Stone, a professor of physics at Syracuse University and one among the collaborators on the new research. Matter and antimatter Every particle of matter has an antiparticle, which is identical in mass but with an opposite electrical charge. When matter and antimatter meet, they annihilate each other. That's a controversy. the massive Bang should have created a constant amount of matter and antimatter, and every one of these particles should have destroyed one another rapidly, leaving nothing behind but pure energy. Clearly, that did not happen. Instead, about 1 in a very billion quarks (the elementary particles that compose protons an...

  A strange report surfaced recently in an exceedingly medical journal and its observers absolutely baffling. crammed with incredible claims a few regions in the middle of the planet can be altering human genetics, the paper has been dismissed as a hoax. But is that each one there's to it? Entitled “Apart from at the middle of Earth Plays the Role of the most important System of Telecommunication for Connecting DNAs, Dark DNAs and Molecules of Water on 4+N- Dimensional Manifold,” the initial paper in question was published by 13 different authors within the Open Access Macedonian Journal of life sciences. In the paper’s abstract, things get weird right from the beginning. “Recently, some scientists from NASA have claimed that there could also be a part like structure at the center of the planet,” it begins. Additional papers began to surface with similarly outlandish claims. as an example, one stated: “The earth’s core is that the biggest system of telecommunication which exchanges...

  Quantum physics promises huge advances not just in quantum computing but also during a quantum internet – a next-generation framework for transferring data from one place to a different. Scientists have now invented technology suitable for a quantum modem that might act as a network gateway. What makes a quantum internet superior to the regular, existing internet that you're reading this through is security: interfering with the info being transmitted with quantum techniques would essentially break the connection. It's as near unhackable as you'll possibly get. As with trying to provide practical, commercial quantum computers though, turning the quantum internet from potential to reality is taking time – not surprising, considering the incredibly complex physics involved. A quantum modem can be a really important success for the technology. "In the long run, a quantum internet might be wont to connect quantum computers located in several places, which might considera...

  Experts say the proper reasonable system could carry spacecraft to Saturn in only two years. The direct fusion drive (DFD), an idea being developed by Princeton physical science Laboratory, would make extremely fast work of the nearly billion miles between Earth and Saturn. Researchers there say the Princeton field reversed configuration-2 (PFRC-2) drive might be the key to feasible travel within our scheme. The research team chose Saturn’s moon Titan as a perfect, well, moonshot. The #1 moon in our system encompasses plenty of scientific interest thanks to its surface liquids, and therefore the indisputable fact that they’re hydrocarbons means Titan could even become a refueling waystation in some far-future space transportation system. Universe Today reports: “[T]he engine itself exploits many of the benefits of aneutronic fusion, most notably a very high power-to-weight ratio,” an announcement reads. “The fuel for a DFD drive can vary slightly in mass and contains deuterium an...

 Seven years ago, in 2012, one paper, which was published naturally Physics, has shown the globe that our present is, in fact, constrained by our future and our past. this suggests that what occurs now, in our past, could also be obsessed on what occurred in our future. Although this failed to be for lots of individuals, for people who are in physics matters, it made a large difference. Well, physical science could also be said to be something which plenty of individuals find it difficult to wrap their heads around. Although plenty of them will do their best so as to understand it, they will sometimes be left in confusion. This wasn't the only time quantum physicists studied the time structure. It was exhausted the past, and something which goes to be researched and studied within the years within the future. This ‘delayed-choice’ experiment has been a groundbreaking one which is additionally said to be the modified sort of the so-called double slit experiment. This double silt exp...

 In 1934, theoretical physicist Wigner proposed a replacement style of crystal. If the density of charged electrons may be maintained below a particular level, the subatomic particles can be held in a very repeating pattern to form a crystal of electrons; this concept came to called a Wigner crystal. That's plenty easier said than done, though. Electrons are fidgety, and it's extremely difficult to urge them to take a seat still. Nevertheless, a team of physicists has now achieved it - by trapping the wiggly little brats between a pair of two-dimensional semiconducting tungsten layers. Conventional crystals - like diamonds or quartz - are formed from a lattice of atoms arranged in an exceedingly fixed, three-dimensional repeating grid structure. per Wigner's idea, electrons may well be arranged in an exceedingly similar fashion to make a solid crystal phase, but as long as the electrons were stationary. If the density of the electrons is low enough, the Coulomb repulsion be...

 The universal regulation of any reasonably wave – be it electromagnetic or gravitational – travelling through a vacuum has been known since physicist developed his theory of Einstein's special theory of relativity in 1905. But the most speed of sound moving through a solid or a liquid has just been calculated for the primary time. it's about 36 kilometres per second, over 8000 times not up to the speed of sunshine during a vacuum. To make this calculation, Kostya Trachenko at the Queen Mary University of London and his colleagues started with two well-known physical constants: the ratio of proton mass to the electron mass, and also the spectrum line constant, which characterises the strength of interactions between charged particles. Trachenko says we've a fairly good idea of those values because if they were changed even touch, the universe wouldn’t observe all prefer it does. “If you modify these constants by some per cent, then the proton may not be stable anymore, and ...

 Experts say the correct quite system could carry spacecraft to Saturn in barely two years. The direct fusion drive (DFD), an idea being developed by Princeton physical science Laboratory, would make extremely fast work of the nearly billion miles between Earth and Saturn. Researchers there say the Princeton field reversed configuration-2 (PFRC-2) drive can be the key to feasible travel within our scheme. The research team chose Saturn’s moon Titan as a perfect, well, moonshot. The #1 moon in our scheme encompasses a tidy sum of scientific interest due to its surface liquids, and also the undeniable fact that they’re hydrocarbons means Titan could even become a refueling waystation in some far-future space transportation. Universe Today reports: “[T]he engine itself exploits many of the benefits of aneutronic fusion, most notably a particularly high power-to-weight ratio,” a release reads. “The fuel for a DFD drive can vary slightly in mass and contains deuterium and a helium-3 iso...

Among the strange features of quantum physics is that the phenomenon called quantum tunneling, where a particle overcomes a barrier that may be impassable in other types of physics. Generations of physics students are taught this phenomenon with analogies like objects passing through solid walls, but the time this process takes has always been a mystery. a brand new study has set an edge on the time it takes, one so short the method could also be instantaneous, during which case these particles would be exceeding the speed of sunshine. Tunneling certainly happens so quickly it's hard to live. Recent efforts have used heavier atoms, necessitating indirect measurements. Dr. Igor Litvinyuk of Griffith University told IFLScience the Australian Attosecond Science Facility is that the only place within the world with all three kinds of equipment required to live the time it takes electrons to tunnel from the grip of hydrogen atoms. Litvinyuk helped put that combination to use, reporting ...

 When it involves cosmology, astronomy, and physics, there's no shortage of off-the-wall arguments and hypotheses. While new discoveries from the first moments of the large Bang and quantum and high-energy physics still amaze us and fill within the gaps of our mysterious universe, there remains a shocking number of questions we still can’t answer. The most fundamental of those questions revolve around “why anything” and “why consciousness.” Why is there anything here at all? What primal state of existence could have possibly birthed all that matter, energy, and time, all that everything? and the way did consciousness arise—is it some fundamental proto-state of the universe itself, or an emergent phenomenon that's purely neurochemical and material in nature? A new physics hypothesis attempts to answer both questions at an identical time with a brand new spin on panpsychism that weds aspects of Nick Bostrom’s Simulation Argument with something called “timeless emergentism.” The h...

 Radiation from space might be an enormous problem for quantum computers because cosmic rays can disturb their fragile inner workings and limit the sorts of calculations they will in the future perform. Quantum computers are products of quantum bits, or qubits, which are accustomed store and manipulate quantum information. When designing qubits, one of all the foremost important factors is that the coherence time, which is that the amount of your time a qubit can remain during a particular state. “The longer you've got, the more calculations you'll be able to do, the more complex calculations, and therefore the more reliable those calculations are,” says Brent VanDevender at the Pacific Northwest National Laboratory (PNNL) in Washington state. “Even some milliseconds isn't really long enough to try and do general-purpose quantum computing.” He and his colleagues used two qubits to check what proportion of radiation within the environment affects the coherence time of a sort...

 We know that the realm of natural philosophy is science operating at a mind-bogglingly small scale, thus watching quantum interactions happen is often exciting. Now, physicists have managed to watch billions upon billions of entangled electrons passing through a metal film. The film may be a mixture of ytterbium, rhodium and silicon, and is what's referred to as a 'strange metal', one that does not act for sure at very low temperatures. "With strange metals, there's an unusual connection between electrical phenomenon and temperature," explained physicist Silke Bühler-Paschen from Vienna University of Technology in Austria. "In contrast to simple metals like copper or gold, this doesn't seem to result to the thermal movement of the atoms, but to quantum fluctuations at absolutely the zero temperature." These fluctuations represent a quantum criticality – that time between quantum states which are the equivalent of transition between liquids, soli...
