Going Nuclear Over the Pacific

Earthquake science could have predicted North Korea’s nuclear climbdown
Posted by Quinn Sena in categories: energy, existential risks, nuclear weapons, policy, science
Just days after North Korea announced it was suspending its testing programme, scientists revealed that the country’s underground nuclear test site had partially collapsed. This assessment was based on data gathered from smaller earthquakes that followed North Korea’s biggest nuclear test in 2017. A new study published in Science has now confirmed the collapse using satellite radar imaging.
The collapse may have played a role in North Korea’s change in policy. If correct, and with the hindsight of this research, we might have speculated that the North Koreans would want to make such an offer of peace. This shows how scientific analysis normally reserved for studying natural earthquakes can be a powerful tool in deciphering political decisions and predicting future policy across the globe.
In fact, another unusual earthquake in South Korea in 2017 also has the potential to affect geopolitics, this time by changing energy policy. “Seismic shift” may be a cliche often used by journalists and policymakers to describe changing political landscapes, but these recent earthquakes along the Korean Peninsula remind us there can really be authentic links between seismic events and global affairs.

Why it is dangerous to build ever larger big bang machines

CERN has revealed plans for a gigantic successor of the giant atom smasher LHC, the biggest machine ever built. Particle physicists will never stop to ask for ever larger big bang machines. But where are the limits for the ordinary society concerning costs and existential risks?
CERN boffins are already conducting a mega experiment at the LHC, a 27km circular particle collider, at the cost of several billion Euros to study conditions of matter as it existed fractions of a second after the big bang and to find the smallest particle possible – but the question is how could they ever know? Now, they pretend to be a little bit upset because they could not find any particles beyond the standard model, which means something they would not expect. To achieve that, particle physicists would like to build an even larger “Future Circular Collider” (FCC) near Geneva, where CERN enjoys extraterritorial status, with a ring of 100km – for about 24 billion Euros.
Experts point out that this research could be as limitless as the universe itself. The UK’s former Chief Scientific Advisor, Prof Sir David King told BBC: “We have to draw a line somewhere otherwise we end up with a collider that is so large that it goes around the equator. And if it doesn’t end there perhaps there will be a request for one that goes to the Moon and back.”
“There is always going to be more deep physics to be conducted with larger and larger colliders. My question is to what extent will the knowledge that we already have be extended to benefit humanity?”

Should We Build A Fast Nuclear Test Reactor Or Continue To Be Beholden To Russia?
Posted by Klaus Baldauf in categories: climatology, nuclear weapons, sustainability
In the end, however, if the critics quoted in the Science article don’t care about global warming, fine – many people don’t. If they think renewables alone can do it, fine – some people do. I’m sure they’re well-intentioned. However, every leading climate scientist from Jim Hansen on down knows that we will not achieve any of our climate goals without a dramatic increase in both nuclear and renewables.
Since fast-reactors, like those that will be tested in the VITR, can get ten times the power out of the same fuel, can burn spent fuel and even depleted uranium like our old Iraqi tank armor, when we get to fast reactors as a significant portion of our energy we will have several thousand years of low-carbon power on hand.
That’s more energy than exists in all the coal, oil and natural gas in the ground right now.

What is a Drone? (Future A to Z)
Posted by Johnny Boston in categories: automation, computing, drones, electronics, military, nuclear weapons, robotics/AI
Drones. Drone is a word you see pretty often in today’s pop culture. But drones seem to be an extremely diverse species. Even flightless vehicles are occasionally referred to as drones. So what exactly is a drone?
In this video series, the Galactic Public Archives takes bite-sized looks at a variety of terms, technologies, and ideas that are likely to be prominent in the future. Terms are regularly changing and being redefined with the passing of time. With constant breakthroughs and the development of new technology and other resources, we seek to define what these things are and how they will impact our future.
