Their theory, known as “timescape cosmology,” suggests that what we perceive as cosmic acceleration might actually result from how we measure and interpret cosmic distances. This new ...

Dark energy, the mysterious phenomenon that powers the expansion of the universe, may undergo periodic 'violent transitions' ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. Dark energy ...

Therefore, physicists keep looking for alternative explanations for cosmic acceleration. Earlier, in a paper titled "On the accelerated expansion of the universe," published in the journal ...

"We would like to understand the difference between these systems, which holds the clue to understand just how many cosmic ...

Hi I’m Rachel! I work with Dr. Jeremey Darling in CASA. My research focuses on measuring cosmic acceleration in real time through secular redshift drift. I study the spectra of distant quasars to find ...

Cosmic microwave background is a sea of radiation ... dark energy that is currently speeding up the universe’s acceleration. It seemed to be a blunder because observations by Edwin Hubble ...

This was the first super cosmic ray acceleration source to have ever been authenticated. Cosmic rays are charged particles from outer space, mainly composed of protons. The origin of cosmic rays ...
