A new study of one of the universe's fundamental constants casts doubt on a popular theory of dark energy, scientists say. Dark energy is the name given to whatever is causing the expansion of the ...

Dark energy, which forms almost three-quarters of the universe, is the most mysterious stuff known to man. A new set of Chandra X-Ray Observatory data, however, has given scientists good information ...

Physicists are now celebrating the 100th anniversary of the cosmological constant. On this occasion, two recent articles highlight its role in modern physics and cosmology. Before becoming widely ...
