"As yet, nobody has managed to understand what gives rise to this strange phenomenon, and explaining dark energy remains one ...

The discovery that the universe was dominated by this constant energy shocked everyone, especially as Einstein had called the cosmological constant his "biggest blunder." Today, cosmologists still ...

Scientists have come up with a number of possible explanations. One of the leading concepts is the ‘cosmological constant’ theory, in which the energy of empty space itself causes cosmic acceleration.

Yet its origin remains a mystery. It is invisible, elusive, and up until now, scientists considered it a cosmological constant, stable over time. However, recent findings challenge this hypothesis.

That's why astronomers have thought that dark energy could be the same thing as Albert Einstein's "cosmological constant," which was an extension of his theory of general relativity. Einstein ...

Many scientists have also pointed out that the known properties of dark energy are consistent with a cosmological constant, a mathematical Band-Aid that Albert Einstein added to his theory of ...

The model starts with a description of space that is expanding due to a cosmological constant, much like the dark energy we observe in the modern-day cosmos. Within that backdrop, the quantum foam ...

New study reveals Hubble constant discrepancy in cosmic expansion Researchers say results may rewrite current cosmology theories Astronomers find faster expansion rate with DESI and Cepheid stars ...

Astronomers also use gravitational lensing to map dark matter — an invisible substance that makes up about 85% of the universe's mass. They create the maps by observing how much dark matter ...
