“Astonishing New Theory” –‘Dark Matter & Dark Energy Are a Fluid’

A simulation of the dark matter distribution in the universe 13.6 billion years ago.

 

“We now think that both dark matter and dark energy can be unified into a fluid which possesses a type of ‘negative gravity’, repelling all other material around them,” says Jamie Farnes from the Oxford University e-Research Center. “The outcome seems rather beautiful: dark energy and dark matter can be unified into a single substance, with both effects being simply explainable as positive mass matter surfing on a sea of negative masses.”

“Full-Blown Incompatibility” –Hubble and Gaia Discoveries Could Point to a New Physics Underlying the Universe

 

“The tension seems to have grown into a full-blown incompatibility between our views of the early and late time universe,” said Nobel Laureate Adam Riess of the Space Telescope Science Institute and Johns Hopkins University. “At this point, clearly it’s not simply some gross error in any one measurement. It’s as though you predicted how tall a child would become from a growth chart and then found the adult he or she became greatly exceeded the prediction. We are very perplexed.”

“Fluctuations of Dark Matter Across the Cosmos have Changed Over Billions of Years”

 

“Fluctuations measured by the Planck Satellite are like a precise arrow shot from the early Universe, and we have measured where the arrow landed with Subaru Hyper Suprime-Cam,” said Surhud More, Inter-University Center for Astronomy & Astrophysics.

Positron Annihilation into Dark Matter Experiment –“The Search for a 5th Force That Would Completely Change the Paradigm”

This month, scientists will turn on an instrument, the Positron Annihilation into Dark Matter Experiment (PADME), at the National Institute of Nuclear Physics near Rome, which is designed to hunt down a mysterious ‘dark force’ to explain the hidden realm of the cosmos –a fifth force that would “completely change the paradigm”.
