How the best alternative to “quantum spookiness” failed

Posted by in categories: information science, quantum physics, space

For all of history, there’s been an underlying but unspoken assumption about the laws that govern the Universe: If you know enough information about a system, you can predict precisely how that system will behave in the future. The assumption is, in other words, deterministic. The classical equations of motion — Newton’s laws — are completely deterministic. The laws of gravity, both Newton’s and Einstein’s, are deterministic. Even Maxwell’s equations, governing electricity and magnetism, are 100% deterministic as well.

But that picture of the Universe got turned on its head with a series of discoveries that began in the late 1800s. Starting with radioactivity and radioactive decay, humanity slowly uncovered the quantum nature of reality, casting doubt on the idea that we live in a deterministic Universe. Predictively, many aspects of reality could only be discussed in a statistical fashion: where a set of probable outcomes could be presented, but which one would occur, and when, could not be precisely established. The hopes of avoiding the necessity of “quantum spookiness” was championed by many, including Einstein, with the most compelling alternative to determinism put forth by Louis de Broglie and David Bohm. Decades later, Bohmian mechanics was finally put to an experimental test, where it failed spectacularly. Here’s how the best alternative to the spooky nature of reality simply didn’t hold up.

China launches mysterious new spy satellite

Posted by in category: space

It was the country’s 35th successful rocket launch this year.

China’s space agency, the China National Space Administration (CNSA) continues its impressive launch cadence for this year with its latest launch. The agency launched a mystery spy satellite that may gather military intelligence for the country, a report from Space.com reveals.

The satellite, called Yaogan 33, launched atop China’s Long March 4C rocket from the Jiuquan Satellite Launch Center in the Gobi Desert at 7:44 pm (23:44 GMT) on Friday, September 2.

How Our World Emerges from Quantum Physics — Where Did The Universe Come From?

Posted by in categories: quantum physics, space

Quantum Physics is the bedrock of physical reality, as far as we know, but things behave very differently at the quantum level than they do in the world as we know it. Today, we learn how large number probability turns a probabilistic world into a deterministic one.

Astronomers Discover Clouds of Sand In The Atmosphere of A Failed Star

Posted by in category: space

New observations from the James Webb Space Telescope have given us direct confirmation that some alien worlds have clouds of rock.

The telescope has directly detected silicate clouds in the atmosphere of a brown dwarf – the first time, according to an international team of astronomers, that such a detection has been made in a planetary-mass companion outside the Solar System.

The complete findings, the team says, constitute the best spectrum yet for a planetary mass-object. These results could not only help us better understand these so-called ‘failed stars’, but represent just a foretaste of what the JWST can do.

Robot Sales Hit Record High in North America for Third-Straight Quarter

Posted by in categories: business, employment, food, robotics/AI, space

This will create new types of jobs especially in software industries.


ANN ARBOR, Mich.—()—For the third-straight quarter, robot sales in North America hit a record high, driven by a resurgence in sales to automotive companies and an ongoing need to manage increasing demand to automate logistics for e-commerce. According to the Association for Advancing Automation, of the 12,305 robots sold in Q2 2022, 59% of the orders came from the automotive industry with the remaining orders from non-automotive companies largely in the food & consumer goods industry, which saw a 13% increase in unit orders over the same period, April through June, in 2021.
