Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is estimated to account for most of ...

Astronomers are a step closer to cracking one of the secrets of dark energy—the mysterious force believed to be causing the universe's accelerated expansion.

Whether the universe will “end” at all is not certain, but all evidence suggests it will continue being humanity’s cosmic home for a very, very long time.

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

For nearly three decades, the scientific community has believed that dark energy (comprising roughly 70% of the universe) acts as a kind of anti-gravity force pushing galaxies apart at an ...

One of the greatest mysteries in cosmology is the nature of what we refer to as dark energy. This mysterious force drives the expansion of the universe to accelerate. Dark energy is an unknown ...

ABSTRACT: Current accelerated expansion of our universe, as indicated by number of observations, is addressed in the present work. Like several works in literature, we postulate dark energy as ...

A recent study by Rajendra Gupta, published in "Galaxies," proposes that cosmic phenomena conventionally ascribed to dark matter and dark energy can be explained by the temporal weakening of ...

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes ...

The universe is approaching the midpoint of its 33-billion-year lifespan, a Cornell physicist calculates with new data from dark-energy observatories. After expanding to its peak size about 11 billion ...

For a quarter century, cosmology has leaned on one framework to explain how the universe expands. Known as the ΛCDM model, it assumes about 70 percent of the cosmos is filled with an unseen force ...
