The discovery of a second ultra-large structure in the remote universe has further challenged some of the basic assumptions about cosmology.
The images to emerge from the James Webb Space Telescope have captured details of the cosmos never seen before, leaving the scientific community and public alike in a state of awe. In a Tweet, former President Barack Obama ...
In trying to understand the nature of the cosmos, some theorists propose that the universe expands and contracts in endless cycles.
The Codex Telleriano Remensis, created in the 16th century in Mexico, depicts earthquakes in pictograms that are the first written evidence of earthquakes in the Americas in pre-Hispanic times, according to a pair of researchers ...
Philosophers have debated the nature of "nothing" for thousands of years, but what has modern science got to say about it? In an interview with The Conversation, Martin Rees, Astronomer Royal and Emeritus Professor of Cosmology ...
In the first moments after the Big Bang, the universe expanded many billions of times faster than today. Such rapid expansion is likely due to a primordial force field acting with a new particle, the inflaton. From the latest ...
Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science.
(PhysOrg.com) -- During the past few years, CERN physicist Dragan Hajdukovic has been investigating what he thinks may be a widely overlooked part of the cosmos: the quantum vacuum. He suggests that the quantum vacuum has ...
(PhysOrg.com) -- When scientists discovered in 1998 that the Universe is expanding at an accelerating rate, the possibility that dark energy could explain the observation was intriguing. But because there has been little ...
(PhysOrg.com) -- One of the biggest unsolved problems in astrophysics is that galaxies and galaxy clusters rotate faster than expected, given the amount of existing baryonic (normal) matter. The fast orbits require a larger ...
