An anonymous reader quotes a report from TechCrunch: “We want to miniaturize accelerator technology in a way that makes it a more accessible research tool,” explained project lead Jelena Vuckovic in a Stanford news release. But this wasn’t designed like a traditional particle accelerator like the Large Hadron Collider or one at collaborator SLAC’s National Accelerator Laboratory. Instead of engineering it…

Thousands of exoplanets may orbit supermassive black holes
It sounds unbelievable, but a new study from Kagoshima University and the National Astronomical Observatory of Japan says that exoplanets – thousands of them – could be orbiting supermassive black holes. Source: https://earthsky.org/space/thousands-of-exoplanets-may-orbit-supermassive-black-holes…
Epic cosmic explosion detected via faster-than-light particles
Space-based observatories detected a violent explosion in a galaxy billions of light-years away. It became the brightest source of high-energy cosmic gamma rays seen so far. Specialized Earth-based telescopes detected it via faster-than-light particles cascading through Earth’s atmosphere. Source: https://earthsky.org/space/jan-14-2019-gamma-ray-burst-brightest-so-far…
Voyager 2 sends back insights on interstellar space
Voyager 2 left the realm of the sun’s influence a year ago today, becoming the 2nd craft ever to do so. This week, the journal Nature Astronomy published 5 new papers describing what Voyager 2 has been seeing on its journey into the unknown.

NASA creates stunning new black hole visualization
For decades, astronomical theorists have told us that a black hole’s powerful gravity would warp the space around it. This new visualization from NASA’s Goddard Space Flight Center is the best yet at showing exactly how. Source: https://earthsky.org/space/black-hole-visualization-from-side-schnittman-goddard…
New research looks at gamma-ray bursts
Astrophysicists Jon Hakkila of the College of Charleston and Robert Nemiroff of the Michigan Technological University have published research indicating that blasts that create gamma-ray bursts may actually exceed the speed of light in surrounding gas clouds, but do so without violating Einstein’s theory of relativity.

A new alphabet to write and read quantum messages with very fast particles
Quantum information relies on the possibility of writing messages in a quantum particle and reading them out in a reliable way. If, however, the particle is relativistic, meaning that it moves with velocities close to the speed of light, it is impossible for standard techniques to decode the message unambiguously, and the communication therefore fails. …
Under pressure: Balloons for particle acceleration
Balloons can help make a space perfect for a party. Now they also can help when it comes to accelerating particles to near the speed of light. …
Scientists shed new light on mystery origin of ultra-high-energy cosmic ray hotspot
Among many particles arriving from outer space, there are ones with the extremely high energy that travel at nearly the speed of light, which is equivalent of a baseball thrown at a speed of 100 meters per second. New hypothesis for origin of those ultra-high-energy particles has been proposed, thus drawing particular attention from all over the world.

A classic quantum theorem may prove there are many parallel universes
If we accept that information can’t travel faster than the speed of light, a quantum theorem seems to require many worlds that split when you make a measurement Source: https://www.newscientist.com/article/2213756-a-classic-quantum-theorem-may-prove-there-are-many-parallel-universes/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
