Cosmologists probe beyond the Big Bang
A long tradition of cosmology research in Cornell's College of Arts and Sciences has given birth to a vigorous effort by a new generation of cosmologists to understand the Cosmic Microwave Background (CMB), the thermal radiation ...
Physicist suggests speed of light might be slower than thought
Astronomers challenge Cosmological Model
(Phys.org) —Astronomers Professor Chris Collins and Dr Ian McCarthy from LJMU's Astrophysics Research Institute are challenging the view that the currently preferred cosmological model of the Universe is ...
Dark energy alternatives to Einstein are running out of room
(Phys.org)—Research by University of Arizona astronomy professor Rodger Thompson finds that a popular alternative to Albert Einstein's theory for the acceleration of the expansion of the universe does not ...
Is dark energy static or dynamic?
Compact blue dwarf can't hide from Hubble
(Phys.org) -- The NASA/ESA Hubble Space Telescope has captured this view of the dwarf galaxy UGC 5497, which looks a bit like salt sprinkled on black velvet in this image.
Why we've got the cosmological constant all wrong
Leading the quest to crack cosmological mysteries
Sometimes a scientist can only laugh in the face of a seemingly insurmountable challenge.
Why Einstein was wrong about being wrong
If you want to get your mind around the research that won three astronomers the Nobel Prize in physics last week, it helps to think of the universe as a lump of dough - raisin-bread dough, to be precise - mixed, kneaded and ...
Light from galaxy clusters confirms theory of relativity
All observations in astronomy are based on light emitted from stars and galaxies and, according to the general theory of relativity, the light will be affected by gravity. At the same time all interpretations ...
Far-future astronomers could still deduce the Big Bang
(PhysOrg.com) -- One trillion years from now, an alien astronomer in our galaxy will have a difficult time figuring out how the universe began. They won't have the evidence that we enjoy today.
Gas rich galaxies confirm prediction of modified gravity theory
(PhysOrg.com) -- Recent data for gas rich galaxies precisely match predictions of a modified theory of gravity know as MOND according to a new analysis by University of Maryland Astronomy Professor Stacy McGaugh. ...
In Brief: Study backs Einstein notion on expanding universe
Scientists have found new evidence that an idea Albert Einstein regretted ever having may be key to solving a big mystery: why the universe is expanding at an ever-faster clip.
New study suggests researchers can now test the 'theory of everything'
(PhysOrg.com) -- Researchers describe how to carry out the first experimental test of string theory in a paper published tomorrow in Physical Review Letters.
