The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the ...

For decades, cosmologists have had an awkward number sitting at the center of their equations. The universe is expanding, and ...

The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...

Recent surveys hint that the rate of cosmic expansion changes dramatically over time; if that's true, then the universe could ...

The team successfully built the largest, highest-resolution 3D map of the cosmos ever constructed. The completed map charts ...

The cosmological constant problem, or the vacuum catastrophe is a discrepency in the observed values of the vaccuum energy ...

The conclusion of DESI's first survey marks an important milestone for cosmology, which finds itself in a bind for the best ...

The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the ...

Researchers have unveiled a new AI technique, GAME, that sharpens analysis of cosmic data, and a separate theory suggesting ...

The largest 3D map of the universe reveals over 47 million galaxies, but dark energy remains an unsolved mystery.

Cosmological expansion is widely treated as a proven fact. It is not proven. For nearly a century, cosmology has told a simple story about a universe that began in a hot, dense state and has been ...

After more than a decade of development, NASA’s Nancy Grace Roman Space Telescope is entering final preparations for an early ...
