“Dead or Alive?” –Postmortem of Gigantic Galaxies at Dawn of the Cosmos

“We found that its core seems already fully formed at that time,” says Masayuki Tanaka who led a team of researchers of the Cosmic Dawn Center at the Niels Bohr Institute and the National Observatory of Japan about a recently discovered massive galaxy already dying only 1.5 billion years after the Big Bang. “This result pairs up with the fact that, when these dying gigantic systems were still alive and forming stars, they might have not been that extreme compared with the average population of galaxies”, adds Francesco Valentino, author of an article on the past history of dead galaxies appeared in the Astrophysical Journal.

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

Hubble Ultra Deep Field

 

“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)

ESO Observatories Chile

 

“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.

“A Message From the Phantom Cosmos?”

Milky Way Galaxy

 

Did NASA scientists detect a dark matter signal from deep inside the Milky Way? In December of 2017, the Chandra X-Ray Observatory observed a strange and distinctive X-ray signal from deep inside the dynamic center of the Milky Way, the 3.5 keV line, that researchers believed could help them in proving the existence of the hidden, dark side of our universe.
