NASA Sponsored Researcher Suggests It Might Be Possible to Change the Laws of Physics

Posted by in categories: engineering, neuroscience, physics

In an extremely cosmic–brain take, University of Rochester astrophysics professor Adam Frank suggests that a civilization could advance so much that it could eventually tinker with the fundamental laws of physics.

It’s a mind-bending proposition that ventures far beyond the conventional framework of scientific understanding, a reminder that perhaps we should dare to think outside the box — especially as we continue our search for extraterrestrial civilizations.

If a civilization were to be able to change the laws of physics, “the very nature of energy itself, with established rules like energy conservation, would be subject to revision within the scope of engineering,” Frank, who is part of the NASA-sponsored Categorizing Atmospheric Technosignatures program, wrote in an essay for Big Think.

‘This is weird’: Experts ‘shocked’ by record-breaking longevity of Death Valley’s phantom lake

Posted by in category: futurism

A temporary lake at Badwater Basin in Death Valley National Park has persisted for more than six months, which is far longer than it has lasted before. And experts say that it could stick around for quite a while yet.

Study: ancient technique holds thousands of tons of carbon, sequestered over centuries

Posted by in category: futurism

Archaeologists have dug up mysteriously black and fertile patches of ancient soils in hundreds of sites across the Amazon. 🌎⁠ https://www.freethink.com/science/carbon-dark-earth-ancient-technique


The team’s study appears in Science Advances. Other authors include former MIT postdoc and lead author Morgan Schmidt, anthropologist Michael Heckenberger of the University of Florida, and collaborators from multiple institutions across Brazil.

In their current study, the team synthesized observations and data that Schmidt, Heckenberger, and others had previously gathered, while working with Indigenous communities in the Amazon since the early 2000s, with new data collected in 2018–19. The scientists focused their fieldwork in the Kuikuro Indigenous Territory in the Upper Xingu River basin in the southeastern Amazon. This region is home to modern Kuikuro villages as well as archaeological sites where the ancestors of the Kuikuro are thought to have lived. Over multiple visits to the region, Schmidt, then a graduate student at the University of Florida, was struck by the darker soil around some archaeological sites.

Researchers Uncovered a New State of Matter Hidden in The Quantum World

Posted by in categories: particle physics, quantum physics

A team of physicists, including University of Massachusetts assistant professor Tigran Sedrakyan, recently announced in the journal Nature that they have discovered a new phase of matter. Called the “chiral Bose-liquid state,” the discovery opens a new path in the age-old effort to understand the nature of the physical world.

Under everyday conditions, matter can be a solid, liquid or gas. But once you venture beyond the everyday—into temperatures approaching absolute zero, things smaller than a fraction of an atom or which have extremely low states of energy—the world looks very different. “You find quantum states of matter way out on these fringes,” says Sedrakyan, “and they are much wilder than the three classical states we encounter in our everyday lives.”

Sedrakyan has spent years exploring these wild quantum states, and he is particularly interested in the possibility of what physicists call “band degeneracy,” “moat bands” or “kinetic frustration” in strongly interacting quantum matter.

Science Fiction has long contemplated the idea that alien life not based on carbon chemistry such as silicon might exist on distant and strange worlds, or might be made to exist advanced biological engineering. What would such life be like?

To See Black Holes in Detail, She Uses ‘Echoes’ Like a Bat

Posted by in category: cosmology

Packed with mass equal to millions or billions of suns, supermassive black holes lurk at the center of nearly every galaxy.


The astrophysicist Erin Kara measures time lags in black holes’ X-ray glows, which reveal the complexity of the objects’ closest surroundings.
