Dark matter is more than five times as abundant as all the visible matter in the universe. So why can't we see any of it?

Maybe dark energy isn’t an inherent property of space, but actually some kind of as-yet unknown energy field (sometimes called “quintessence” or “dynamical dark energy”). This field ...

Quantum field theory predicts that empty space should nonetheless contain energy, called vacuum energy. This is one candidate for dark energy, but theory predicts that vacuum energy should act ...

Dark energy comprises over two-thirds of the ... Efforts to reconcile this "cosmological constant problem" include invoking scalar fields, modified gravity theories, or multiverse scenarios.

In Particle Cosmology and Astrophysics, Dan Hooper captures the rapid developments in particle cosmology over the past three ...

Using combined observations from ground-based telescopes over nearly four years, the researchers saw the distant galactic ...

Dark energy represents one of the key secrets for modern cosmology ... gives us an idea of the type of measurement we need to make to narrow down the field to a cosmological model, then we can go back ...

“Dark skies provide cover for predators and prey alike, and also conserve energy and water for both ... as natural laboratories for large-scale field studies. At Big Bend, these protections ...

Rather than being like battery chargers, mitochondria are more like the motherboard of the cell.

A groundbreaking new study, recently published on arXiv, challenges one of the most fundamental assumptions in cosmology: ...

Instead of making changes to the LCDM itself, Akrami and his colleagues suggested redefining dark energy as a "quintessence field," which has been used to explain observations of an accelerating ...
