This Experiment Will Make You Believe in Spontaneous Generation of Life. Rogue antimatter found in thunderclouds. The Large Hadron Collider Is Back, Baby. No Big Bang? Quantum equation predicts universe has no beginning. (Phys.org) —The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein's theory of general relativity.
The model may also account for dark matter and dark energy, resolving multiple problems at once. The widely accepted age of the universe, as estimated by general relativity, is 13.8 billion years. Kandiru comments on Chemists Confirm the Existence of New Type of Bond. Superconductivity without cooling : science. A few days ago, CERN launched an Open Data Portal to publicly share data from the Large Hadron Collider. We are some of the scientists behind this project, working to make science more open globally. Ask Us (Almost) Anything about open data, open access,
We unveiled the CERN Open Data Portal to the world recently, releasing samples for education from all the main LHC experiments and around 27 TB of high-level and analysable LHC data from the CMS Experiment. Following CERN’s last AMA, we’re thrilled to be here today to talk to you not only about open science but also our Open Data Portal, #cernopendata and the tools you can build on top of our data. Freakishly Compact Particle Accelerators Could Revolutionize Physics. Computer Simulation Confirms the Possibility of Time Travel. Using photons, Australian scientists managed to create a model in which quantum particles can move back in time.
As it turned out, the laws of standard quantum mechanics may be violated at the same time. Physicists from the University of Queensland in Australia set out to simulate a computer experiment, which could prove the possibility of time travel at the quantum level, predicted in 1991. Are High Energy Neutrinos from Outer Space Really a Big Deal? Hooray!
Goldberg is back! Awesome! "The energy range for these neutrinos was approximately 1 Petaelectronvolt, which to put things in perspective, is roughly 140 times the peak energy of particles in the Large Hadron Collider. It's thousands of times more energy than found in the mass of any particle we've ever yet discovered, which raises the obvious question: where the hell did these things come from? " Scientists Work Out How To Make Matter From Light. Theoretical physicists have proposed a way they think will allow us to create matter from light.
The experiment has yet to be done, but has passed peer review as practical and the inventors are in discussions with experimentalists with the equipment to carry it out. The proposal has created excitement because, while it has been accepted for 80 years that two photons of light could theoretically create matter, for that time the demonstrational proof was regarded as beyond the reach of lab equipment. As Einstein's much quoted, but seldom understood, equation e=mc2 tells us, matter and energy are connected. One can turn into another. Scientists Detect A Particle That Could Be A New Form Of Matter. Fascinating.
New State of Matter Discovered. There was a time when states of matter were simple: Solid, liquid, gas.
Then came plasma, Bose -Einstein condensate, supercritical fluid and more. Now the list has grown by one more, with the unexpected discovery of a new state dubbed “dropletons” that bear some resemblance to liquids but occur under very different circumstances. A New Record for the Highest Temperature We've Ever Created: A Whopping 4 Trillion Degrees Celsius. We are in a moment of transition.
Every day, we discover something new, something inspiring, something awesome... for a billion negative things in our world, there are a billion-billion positive ones, if only we take the time to understand. I want to see the sunrise on another world. I want to know what lies beyond what we know now. I want to face the future, and if it is dark - then I want to try to bring some light to it. Only a fool would think we would encounter no difficulties, only an idiot would believe that the effort involved in understanding the universe wasn't worth the price we will eventually pay or the reward that awaits us.
I guess I believe in hope. Brookhaven National Laboratory — a passion for discovery. Quantum Cloud Simulates Magnetic Monopole. Physicists have created and photographed an isolated north pole — a monopole — in a simulated magnetic field, bringing to life a thought experiment that first predicted the existence of actual magnetic monopoles more than 80 years ago.
In nature, north and south magnetic poles always go hand in hand. Cutting a bar magnet in half just creates two magnets, each of which still has two poles, rather than creating separate north and south poles on each half. Yet their electrostatic cousins, positive and negative charges, exist independently. Synthetic magnetic monopoles have been created in the lab. A magnet always has a north and a south pole.
Even if a magnet is cut in half down to the atomic level, magnetic fields are bipolar. However, in 1931 it was theorized that there are natural monopoles which help explain some of the peculiarities of magnetism. This has never before been tested because scientists have not been able to create monopole elementary particles in the lab that could be studied individually - until now. The research was led by David Hall of Amherst College and the results were published in Nature. Physicists say energy can be teleported 'without a limit of distance' I would say the future is now, but really it's almost here. ...get it?
Yes, electrons are perfectly round. There is no pink light. Accelerator on a chip: Technology could spawn new generations of smaller, less expensive devices for science, medicine. In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured glass chip smaller than a grain of rice. The achievement was reported today in Nature by a team including scientists from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University. "We still have a number of challenges before this technology becomes practical for real-world use, but eventually it would substantially reduce the size and cost of future high-energy particle colliders for exploring the world of fundamental particles and forces," said Joel England, the SLAC physicist who led the experiments.
"It could also help enable compact accelerators and X-ray devices for security scanning, medical therapy and imaging, and research in biology and materials science. " The Very First Image of a Hydrogen Bond. If Time Were 2D… - From Quarks to Quasars. Question: There are lots of articles written about trying to imagine a 4th dimension of space, but what would it be like to live in a universe with a 2nd dimension of time? The short answer: We simply don’t know. This question is a bit more complicated than talking about different spacial dimensions because we experience 3 dimensions of space, and so we can use what we know about life in one dimension (and how it changes when you have two dimensions) to make inferences about what 4 or more dimensions would be like. Model describes universe with no big bang, no beginning, and no end. (PhysOrg.com) -- By suggesting that mass, time, and length can be converted into one another as the universe evolves, Wun-Yi Shu has proposed a new class of cosmological models that may fit observations of the universe better than the current big bang model.
