Computer scientists use artificial intelligence to boost an earthquake physics simulator

Posted by in categories: engineering, physics, robotics/AI

A team of researchers from the Earthquake Research Institute, Department of Civil Engineering and Information Technology Center at the University of Tokyo, and the RIKEN Center for Computational Science and RIKEN Center for Advanced Intelligence Project in Japan were finalists for the coveted Gordon Bell Prize for outstanding achievements in high-performance computing. Tsuyoshi Ichimura together with Kohei Fujita, Takuma Yamaguchi, Kengo Nakajima, Muneo Hori and Lalith Maddegedara were praised for their simulation of earthquake physics in complex urban environments.

Physicists Have a New Idea for Faster-Than-Light Travel

Posted by in categories: energy, physics

Scientists used to think a “warp bubble” would require an impractical amount of energy. That’s starting to change.

NASA Image of Merging Galaxy Clusters Looks Suspiciously Like the USS Enterprise

Posted by in categories: physics, space travel

Two possibilities: Either the image captures two massive galactic clusters in the process of colliding, or NASA is covering up the existence of a starship so big it’s several million light years long.


Humanity’s current understanding of physics may suggest faster-than-light travel is impossible, but researchers here on Earth can still observe happening in places much too far away to ever actually visit (and generally only what they looked like in the distant past). One of them is a galactic collision that, at least from our planetary vantage point, looks an awful lot like a craft going where no man has ever gone before.

SC18: HPC Demand Surges, Accelerated

Posted by in categories: physics, robotics/AI, supercomputing

NVIDIA’s playing a bigger role in high performance computing than ever, just as supercomputing itself has become central to meeting the biggest challenges of our time.

Speaking just hours ahead of the start of the annual SC18 supercomputing conference in Dallas, NVIDIA CEO Jensen Huang told 700 researchers, lab directors and execs about forces that are driving the company to push both into “scale-up” computing — focused on large supercomputing systems — as well as “scale-out” efforts, for researchers, data scientists and developers to harness the power of however many GPUs they need.

Ripples in Space-Time Could Reveal the Shape of Wormholes

Posted by in categories: cosmology, physics

Wormholes — yawning gateways that could theoretically connect distant points in space-time — are usually illustrated as gaping gravity wells linked by a narrow tunnel.

But their precise shape has been unknown.

Now, however, a physicist in Russia has devised a method to measure the shape of symmetric wormholes — even though they have not been proven to exist — based on the way the objects may affect light and gravity. [8 Ways You Can See Einstein’s Theory of Relativity in Real Life].

Does antimatter fall upwards? New CERN gravity experiments aim to get to the bottom of the matter

Posted by in categories: physics, space

Physics tells us that a hammer and a feather, dropped in a vacuum, will fall at the same rate – as famously demonstrated by an Apollo 15 astronaut on the Moon. Now, CERN scientists are preparing to put a spooky new spin on that experiment, by dropping antimatter in a vacuum chamber to see if gravity affects it the same way it does matter – or if antimatter falls upwards instead.

What the general theory of relativity doesn’t explain

Exclusive: Grave doubts over LIGO’s discovery of gravitational waves

Posted by in categories: physics, space

The news we had finally found ripples in space-time reverberated around the world in 2015. Now it seems they might have been an illusion.

LIGO’s detectorsEnrico Sacchetti

THERE was never much doubt that we would observe gravitational waves sooner or later. This rhythmic squeezing and stretching of space and time is a natural consequence of one of science’s most well-established theories, Einstein’s general relativity. So when we built a machine capable of observing the waves, it seemed that it would be only a matter of time before a detection.
