“Antarctica Alert” –Ghostly Invader from a Supermassive Black Hole Detected (2019 Most Popular)

“It’s like a crime scene investigation. The case involves an explosion, a suspect, and various pieces of circumstantial evidence,” said Matthias Kadler, astrophysicist at the University of Würzburg in Germany about the event that occurred on Sept. 22, 2017, when a ghostly particle ejected from a distant supermassive black hole sneaked through the ice of Antarctica at just below the speed of light, with an energy of some 300 trillion electron volts, nearly 50 times the energy delivered by the Large Hadron Collider at CERN, the biggest particle accelerator on Earth.


“Staggering” –The Implications of Infinite Space (2019 Most Popular)

“If space is truly infinite,” observes Dan Hooper, head of the Theoretical Astrophysics Group at the Fermi National Accelerator Laboratory, in At the Edge of Time, “the implications are staggering. Within an infinite expanse of space, it would be hard to see any reason why there would not be an infinite number of galaxies, stars, and planets, and even an infinite number of intelligent or conscious beings, scattered throughout this limitless volume. That is the thing about infinity: it takes things that are otherwise very unlikely and makes them all inevitable.”


The Ultimate Mystery? –“Consciousness May Exist in the Absence of Matter” (2019 Most Popular)

“The universe and the observer exist as a pair. I cannot imagine a consistent theory of the universe that ignores consciousness,” says Stanford University’s Russian-American theoretical physicist, Andrei Linde in his paper, Life Universe Consciousness, about the central mystery of our time, concluding that consciousness may exist by itself, even in the absence of matter, just like gravitational waves, –excitations of spacetime– that may exist in the absence of protons and electrons.


“Great Unknown Question ” –The End of Spacetime (2019 Most Popular)

“Is our universe extremely unnatural, a weird permutation among countless other possibilities, observed for no other reason than that its special conditions allowed life to arise, or, are the properties of the universe are inevitable, predictable, that is, ‘natural,’ locking together into a sensible pattern?” This is the question, the great unknown, that preoccupies theoretical physicist Nima Arkani-Hamed, a professor at the Institute for Advanced Study (IAS) in Princeton, N.J.


“One Trillion Times Age of the Universe” –The Rarest Thing Ever Detected (2019 Most Popular)

“We actually saw this decay happen. It’s the longest, slowest process that has ever been directly observed, and our dark matter detector was sensitive enough to measure it,” said Ethan Brown, a particle physicist at Rensselaer Polytechnic Institute, about a mind-boggling process that takes more than one trillion times longer than the age of the universe, advancing the frontiers of knowledge about the most fundamental characteristics of matter. “It’s amazing to have witnessed this process, and it says that our detector can measure the rarest thing ever recorded.”


“Squeezing Spacetime” –LIGO Researchers End-Run Nature to Detect Gravitational Waves

Gravitational Wave Noise


Intrepid researchers at MIT and Caltech have done what was thought impossible: an end run around nature. They have finessed spooky quantum vacuum –the ground state of energy for the Universe and the source of all potentiality– without violating the laws of nature that will allow the Laser Interferometer Gravitational-wave Observatory (LIGO) to detect ghostly signals, the whispers of gravitational waves, ripples in spacetime at the quantum level, with weekly frequency.
