The discovery that the universe was dominated by this constant energy shocked everyone, especially as Einstein had called the ...

represented by the cosmological constant in Einstein’s general theory of relativity. These days, almost all of cosmology assumes something called the Lambda-CDM model—CDM for cold ...

and a constant amount of dark energy (Einstein's cosmological constant, denoted Lambda). Since its origin approximately 25 years ago, the model has successfully explained a great many observations ...

Recent astronomical observations show that the universe is expanding at an accelerating rate, something that defies our ...

Estimates of how fast the universe is expanding disagree. Could a new form of dark energy resolve the problem?

Some of the earliest galaxies found with JWST are also the brightest. That's a problem for our ideas about the universe.
