“The Phantom Universe” –There’s a New ‘Unknown’ Messing with the Cosmos

NASA Dark Energy

 

There’s a crisis brewing in the cosmos. Measurements over the past few years of the distances and velocities of faraway galaxies don’t agree with the increasingly controversial “standard model” of the cosmos that has prevailed for the past two decades. Astronomers think that a 9 percent discrepancy in the value of a long-sought number called the Hubble Constant, which describes how fast the universe is expanding, might be revealing something new and astounding about the universe.

“Dark Hearts of the Cosmos” –Dazzling New Mergers of Black Holes and Neutron Stars Announced

 

Black Holes in Globular Clusters

 

Gravitational-wave researchers increasingly think that globular clusters, dazzling, celestial “snow globes” populated with hundreds of thousands of closely packed stars, harbor dark “hearts,” loaded with dozens to even hundreds of black holes–by far the greatest concentration of these exotic objects found anywhere in the universe.

Age of the Cosmos? –“Our Understanding of the Universe is Somehow Wrong — Perhaps Fundamentally So”

 

 

The single most important puzzle in today’s cosmology  can be summarized in one question: How old is the universe? For nearly a century — since the discoveries by Einstein, Hubble, LeMaitre and others led to the big bang model of creation — we have known the answer. It is about 13.8 billion years old (using current data).

“Black Holes Don’t Exist” –‘Ripples of Space-time Were Created by Wormholes (Today’s Most Popular)

 

The confirmation of echoes in the LIGO or Virgo signals would be a practically irrefutable proof that astrophysical black holes don’t exist. Time will tell if these wormhole echoes exist or not. “If the result were positive, it would be one of the greatest discoveries in the history of physics,” said Pablo Bueno with KU Leuven University (Belgium).

Astronomers Detect an Illusion From a Neutron Star Merger “Four Times the Speed of Light”

 

 

“We measured an apparent motion that is four times faster than light. That illusion, called superluminal motion, results when the jet is pointed nearly toward Earth and the material in the jet is moving close to the speed of light,” said Kunal Mooley, of the National Radio Astronomy Observatory (NRAO) and Caltech.
