“Heat!” –‘The Universe is Imbued with Wanting Life to Arise and Evolve’ (Today’s Top Space Headline)

 

Observes MIT biophysicist Jeremy England, who created a huge stir in 2013 with a new theory that cast the origin of life as an inevitable outcome of thermodynamics –suggesting that under certain conditions, groups of atoms will naturally restructure themselves so as to burn more and more energy, facilitating the incessant dispersal of energy and the rise of “entropy” or disorder in the universe.

“The Magnificent Seven’ — Hubble Detects a Neutron Star With Features Never Seen Before in a Group of Strange X-ray Pulsars

 

“This particular neutron star belongs to a group of seven nearby X-ray pulsars — nicknamed ‘the Magnificent Seven’ — that are hotter than they ought to be considering their ages and available energy reservoir provided by the loss of rotation energy,” said Bettina Posselt, associate research professor of astronomy and astrophysics at Penn State.

The Huge, Terrifying Idea That Explodes the Big Bang

 

“It probably bothered the first human beings who realized that the world was not just their local valley,” said Leonard Susskind, the Felix Bloch Professor in Physics at Stanford University. “It probably terrified them a little bit, but by now we’re used to the world getting bigger and bigger. The String Theory Landscape just says it’s way bigger than we thought.”

From the Farside: “The One Electron Universe” –‘What if Every Electron Was All the Same Exact Particle?’

 

“I knew, of course, that, at least in our corner of the universe, there are lots more electrons than positrons, but I still found it an exciting idea to think of trajectories in spacetime that could go unrestricted in any direction — forward in time, backward in time, up, down, left, or right.”

“The New Earth?” — Gaia Theory Revised for Evolution of Human Species and Technology –‘Adds a New Level of “Self-Awareness’

 

For around half a century, the ‘Gaia’ hypothesis has provided a unique way of understanding how life has persisted on Earth, championing the idea that living organisms and their inorganic surroundings evolved together as a single, self-regulating system that has kept the planet habitable for life – despite threats such as a brightening Sun, volcanoes and meteorite strikes.

“Heresy!” -Controversial Alternative to General Relativity’s Theory of Gravity –‘Does Not Require Existence of Dark Matter’

An international group of astronomers has revived a previously debunked theory of gravity, arguing that motions within dwarf galaxies would be slower if close to a massive galaxy. The theory, MOND, is a controversial alternative to general relativity, the prevailing Einstein-inspired understanding of the phenomenon of gravity, that requires dark matter to exist, but this has never been proved. MOND does not require dark matter.

“Where are They Hiding?” –NASA’s Former Chief Scientist Says Alien Life Could Be ‘Nowhere and No-When & Two Other Theories’

 

Humanity may be as few as 10 years away from discovering evidence of extraterrestrial life. Once we do, it will only deepen the mystery of where alien intelligence might be hiding. In the seventh episode of Crazy/Genius, the new podcast from The Atlantic on tech, science, and culture, puts the question to several experts, including Ellen Stofan, the former chief scientist of NASA and current director of the Smithsonian National Air and Space Museum; Adam Frank, a writer and astrophysicist at the University of Rochester; Anders Sandberg, a scientist and futurist at the University of Oxford; and Tim Urban, the science essayist at Wait But Why.
