Our current cosmological model—known as lambda cold dark matter, or ΛCDM—relies on hypothesized dark energy to explain the ...

"Dark energy is a misidentification of variations in the kinetic energy of expansion, which is not uniform in a Universe as ...

Scientists challenge the existence of dark energy. They suggest the universe's accelerating expansion is due to uneven ...

Dark energy has been modern physics’ most successful placeholder, a theoretical force invented to explain why galaxies seem ...

Dark energy doesn’t exist, scientists say in shock claim that could solve one of universe’s biggest mysteries - ...

Now that we see the expansion of the universe is accelerating, adding in dark energy as a cosmological constant could neatly explain how space-time is being stretched apart. But that explanation ...

Dark energy and dark matter refers to the unseen energy and matter components of the Universe. Dark matter is invisible, non-baryonic matter hypothesized to explain phenomena including ...

The true number could reveal missing pieces in our understanding of physics, like new particles or a new form of dark energy. Figuring out the true value of the Hubble constant is one of the greatest ...

Dark matter, thought to comprise about 27% of the universe, is a hypothesized form of matter that is invisible but is inferred to exist based on its gravitational effects on ordinary matter - stars, ...

Levi is the director for the Dark Energy Spectroscopic Instrument, DESI, which produced the new map. The instrument consists of 5,000 tiny robots attached to a telescope in Arizona that collects ...

What might explain the anomalous expansion rate? "There are many hypotheses that involve dark matter, dark energy, dark radiation - for example, neutrinos (a type of ghostly subatomic particle ...
