Gravity may have saved the universe after the Big Bang, say researchers
(Phys.org) —New research by a team of European physicists could explain why the universe did not collapse immediately after the Big Bang.
Heat transfer sets the noise floor for ultrasensitive electronics
A team of engineers and scientists has identified a source of electronic noise that could affect the functioning of instruments operating at very low temperatures, such as devices used in radio telescopes ...
Researcher shows that black holes do not exist
Black holes have long captured the public imagination and been the subject of popular culture, from Star Trek to Hollywood. They are the ultimate unknown – the blackest and most dense objects in the universe ...
Is the universe a bubble? Let's check
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.
Small, but plentiful: How the faintest galaxies illuminated the early universe
(Phys.org) —Astronomers investigating behaviour of the universe shortly after the Big Bang have made a surprising discovery: the properties of the early universe are determined by the smallest galaxies. ...
Big Bang breakthrough team allows they may be wrong
American astrophysicists who announced just months ago what they deemed a breakthrough in confirming how the universe was born now admit they may have got it wrong.
Study finds 'lumpy' universe cannot explain cosmic acceleration
(Phys.org) —Astrophysicists at The University of Texas at Dallas are helping to better define the nature of the cosmos by examining why the universe appears to be expanding at an accelerating pace.
