The far distant fates of the Universe offer a number of possibilities, but if dark energy is truly a constant, as the data indicates, it will continue to follow the red curve, leading to the long-term ...

It is dangerous to bet against Einstein. Cosmological research shows that the rate at which the Universe expands is increasing, rather than decreasing as had previously been thought. The concept of ...

The cosmological constant is presumably an enigmatic form of matter or energy that acts in opposition to gravity and is considered by many physicists to be equivalent to dark energy. Nobody really ...

DESI has made the largest 3D map of our universe. The Earth is at the central vertex, and every dot is a galaxy. DESI collaboration and KPNO/NOIRLab/NSF/AURA/R ...

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 ...

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 ...

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 ...
