"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 ...

"Up to this year, most observations were consistent, with dark energy being the cosmological constant. Nonetheless, 2024 was full of hints pointing out this might not be the case." 2024 was a big ...

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.

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 ...

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 ...

New research confirms the Universe is expanding faster than theoretical models predict, intensifying the Hubble tension.

It encompasses cold dark matter (CDM), normal matter and radiation, and the cosmological constant (Λ), which accounts for dark energy. The model has been successful in explaining several ...

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 ...
