Could time itself actually explain our universe's expansion? Our current cosmological model—known as lambda cold dark matter, ...

The majority of our evidence for dark matter’s existence comes from observing visible (or baryonic) matter that does not ...

The Vera C. Rubin Observatory is set to detect millions of exploding vampire stellar remnants called "white dwarfs," shedding ...

Evidence, Theory and Constraints will be useful to those who wish to broaden or extend their research interests, for instance ...

Scientists are keen to get to the bottom of the dark matter puzzle because this phenomenon accounts for the vast majority of the "stuff" in the universe — about 85%, in fact. That means everything we ...

A new study on exploding stars has provided the first evidence for an alternative model of the universe, known as Timescape.

"This discovery poses a challenge to the Lambda Cold Dark Matter model, which may struggle to account for the formation of such small, aligned groups of galaxies in isolated environments.

Our current cosmological model—known as lambda cold dark matter, or ΛCDM—relies on hypothesized dark energy to explain the accelerating expansion of the universe. However, one competing ...

The ΛCDM model is the standard model of cosmology describing the universe's evolution, expansion, and structure. It encompasses cold dark matter (CDM), normal matter and radiation, and the ...

The backbone of modern cosmology is the Lambda-Cold Dark Matter (Lambda-CDM) model. It describes a universe where a dark energy – denoted with Λ, the Greek letter Lambda – is the driving ...

Cold, heavy dark matter tends to produce extremely ... This is the first step to confirming a key prediction of the fuzzy dark matter model. However, there is still a lot of work to be done.

But the object's density would need to be significantly higher than what is predicted by traditional cold dark matter (CDM ... called N-body simulations to model the behavior of a collapsing ...
