Ghostly “Axiogenesis” –Solves Enduring Mystery of Excess Matter in the Universe

 

Infinitesimally light, the ghostly QCD axion–is at least one billion times lighter than a proton provides clues into three missing pieces of the physics jigsaw puzzle –enduring questions in fundamental physics: How can the Standard Model of particle physics be extended to explain the cosmological excess of matter over antimatter? What is dark matter? And what is the theoretical origin of an unexpected but observed symmetry in the force that binds protons and neutrons together?

“The D-Star Hexaquark”–It’s Discovery Could Solve the Big Mystery of Dark Matter

Dark Matter Particles

 

Theories about the origin of dark matter in the universe –one of the biggest questions in science–vary from suggesting that it may be older than the Big Bang to particles the size of galaxies to highly-speculative dark-matter life, consistent with the known laws of the universe.

“Quirk in the Cosmos?” –‘Alpha Factor’ has Profound Implications for Physics and Life

Early galaxies

 

Is life on earth, and perhaps the Milky Way, due to the alpha, the fine-structure constant, the coupling constant for the electromagnetic force? If alpha were just 4% bigger or smaller than it is, stars wouldn’t be able to make carbon and oxygen, which would have made it impossible for life as we know it in our Universe to exist. Research by astrophysicist John Webb on varying constants of nature will profoundly impact our view of the universe if validated.

“Buried in the Data” –XMM-Newton Space-Telescope Reveals ‘Impossible’ Super-Flare from a Tiny Star

 

J0331-27 L Dwarf Star

 

A tiny star known by its catalog number J0331-27, an L dwarf just above the boundary of actually being a star about eight percent the Sun’s mass, has been discovered emitting an enormous ‘super flare’ of X-rays—a dramatic high-energy eruption. In a matter of minutes, it released more than ten times more energy of even the most intense flares generated the Sun, posing a fundamental problem for astronomers, who did not think it possible on stars that small.

Massive Black Holes at the Big Bang –“May Harbor Alien Universes With Different Laws of Physics”

Hubble Deep Field

 

“If our universe is just one of an infinite number, then once inflation stopped in ours, pockets within it that had been inflating would have then collapsed into black holes. The longer each pocket inflated, the more massive the black hole,” suggested Alexander Vilenkin, professor of physics and director of the Institute of Cosmology at Tufts University and author of Many Worlds in One: The Search for Other Universes.

“All’s Quiet on Betelgeuse” –Prelude to a Realtime Supernova?

 

 supergiant star Betelgeuse

 

Although it’s far enough away to keep Earth safe from radiation when it goes supernova, red supergiant star Betelgeuse is about 700 times the size of our sun, with a radius roughly equivalent to the orbit of Jupiter. “It would be astounding,” said Andy Howell, an astronomer at the Las Cumbres Observatory and the University of California at Santa Barbara about Betelgeuse’s inevitable explosion.
