Hubble watches neutron stars collide and explode to create black hole and ‘birth atoms’

Posted by in categories: cosmology, particle physics

“We can now see the moment where atomic nuclei and electrons are uniting in the afterglow,” team member Rasmus Damgaard, a researcher at the Cosmic DAWN Center, said in a statement. For the first time, we see the creation of atoms, we can measure the temperature of the matter, and we can see the microphysics in this remote explosion.”

“It is like admiring three cosmic background radiation surrounding us from all sides, but here, we get to see everything from the outside. We see before, during, and after the moment of birth of the atoms.”

Neutron stars are born when stars at least 8 times as massive as the sun exhaust their fuel for nuclear fusion and can no longer support themselves against their own gravity.

Newly discovered quantum object could usher in new era of technology

Posted by in categories: computing, quantum physics

Once relegated to theory, a newly discovered quantum object could be used to create new devices that will outpace modern electronics.

A new kind of quantum object called orbital angular momentum monopole has been identified that could revolutionize the emerging field of orbitronics, which leverages the rotational quantum states of electrons for next-generation computing devices that are faster, more efficient, and with dramatically lower power consumption.

As a result, orbitronics is seen as a potential successor to traditional electronics, where data is stored, transferred, and manipulated by controlling electric currents within transistors. As transistor sizes approach the atomic scale in order to fit more components onto a single computer ship, there will eventually be a limit where a transistor cannot become any smaller.

What Is AI Superintelligence? Could It Destroy Humanity? And Is It Really Almost Here?

Posted by in categories: futurism, robotics/AI

In 2014, the British philosopher Nick Bostrom published a book about the future of artificial intelligence with the ominous title Superintelligence: Paths, Dangers, Strategies. It proved highly influential in promoting the idea that advanced AI systems—“superintelligences” more capable than humans—might one day take over the world and destroy humanity.

A decade later, OpenAI boss Sam Altman says superintelligence may only be “a few thousand days” away. A year ago, Altman’s OpenAI cofounder Ilya Sutskever set up a team within the company to focus on “safe superintelligence,” but he and his team have now raised a billion dollars to create a startup of their own to pursue this goal.

What exactly are they talking about? Broadly speaking, superintelligence is anything more intelligent than humans. But unpacking what that might mean in practice can get a bit tricky.

AI window-washing robots make their U.S. debut in Dallas

Posted by in category: robotics/AI

DALLAS – Cleaning high-rise windows is an incredibly dangerous job, but artificial intelligence may replace it.

An Israeli-based company launched the U.S. debut of its spider-like robot in North Texas.

It’s not a bird or a plane people watched at the 17Seventeen McKinney building in uptown Dallas.

Joachim Keppler — The Path to Sentient Robots: AI Consciousness in the Light of New Insights …

Posted by in categories: chemistry, quantum physics, robotics/AI

The question of the conditions under which Artificial Intelligence (AI) can transcend the threshold of consciousness can only be answered with certainty if we manage to unravel the mechanism underlying conscious systems. The most promising strategy to approach this goal is to unveil the brain’s functional principle involved in the formation of conscious states and to transfer the findings to other physical systems. Empirical evidence suggests that the dynamical features of conscious brain processes can be ascribed to self-organized criticality and phase transitions, the deeper understanding of which requires methods of quantum electrodynamics (QED). QED-based model calculations reveal that both the architectural structure and the chemical composition of the brain are specifically designed to establish resonant coupling to the ubiquitous electromagnetic vacuum fluctuations, known as zero-point field (ZPF). A direct consequence of resonant brain-ZPF coupling is the selective amplification of field modes, which leads us to conclude that the distinctive feature of conscious processes consists in modulating the ZPF. These insights support the hypothesis that the ZPF is a foundational field with inherent phenomenal qualities, implying that the crucial condition for AI consciousness lies in a robot’s capacity to tap into the phenomenal spectrum immanent in the ZPF.

We’ve seen particles that are massless only when moving one direction

Posted by in categories: materials, particle physics

Inside a hunk of a material called a semimetal, scientists have uncovered signatures of bizarre particles that sometimes move like they have no mass, but at other times move just like a very massive particle.

Science may have found its first dark-matter detector

Posted by in categories: cosmology, science

Scientists in Virginia are looking for mysterious dark matter — and have turned to really old rocks.

The substance, which makes up more than 80 percent of all matter in the universe, shapes and affects the cosmos. But it is entirely invisible and remains undetectable by normal sensors and techniques.

Analyzing billion-year-old rocks, researchers at Virginia Tech hope to find traces of dark matter. The idea was first proposed in the 1980s. Technological advances since then led them to revisit the idea. What if there were traces in Earth’s minerals?

Chemists break rule and overturn “one hundred years of conventional wisdom”

He added: “People aren’t exploring anti-Bredt olefins because they think they can’t.”

“We shouldn’t have rules like this—or if we have them, they should only exist with the constant reminder that they’re guidelines, not rules.”

He added: “It destroys creativity when we have rules that supposedly can’t be overcome.”

SpaceX wants to test refueling Starships in space early next year

Posted by in category: space travel

SpaceX will attempt to transfer propellant from one orbiting Starship to another as early as next March, a technical milestone that will pave the way for an uncrewed landing demonstration of a Starship on the moon, a NASA official said this week.

Much has been made of Starship’s potential to transform the commercial space industry, but NASA is also hanging its hopes that the vehicle will return humans to the moon under the Artemis program. The space agency awarded the company a $4.05 billion contract for two human-rated Starship vehicles, with the upper stage (also called Starship) landing astronauts on the surface of the moon for the first time since the Apollo era. The crewed landing is currently scheduled for September 2026.
