(PhysOrg.com) -- In trying to understand how everything came to be as it appears today, astrophysicists have put together theories that seek to explain how events transpired from the time of the Big...
View ArticleDetection of cosmic effect may bring universe's formation into sharper focus
(PhysOrg.com) -- The first observation of a cosmic effect theorized 40 years ago could provide astronomers with a more precise tool for understanding the forces behind the universe's formation and...
View ArticlePhysicists search for new physics in primordial quantum fluctuations
(PhysOrg.com) -- Inflation, the brief period that occurred less than a second after the Big Bang, is nearly as difficult to fathom as the Big Bang itself. Physicists calculate that inflation lasted for...
View ArticleThe earth is not at rest
(Phys.org) -- The Earth is not at rest. It orbits the Sun, which in turn orbits the center of the Milky Way Galaxy, which in turn moves within the Local Group of Galaxies - a collection of about fifty...
View ArticleNo evidence for 'knots' in space
(Phys.org) -- Theories of the primordial Universe predict the existence of knots in the fabric of space - known as cosmic textures - which could be identified by looking at light from the cosmic...
