Mini-spiral galaxies may transform how dark matter is perceived
... the latter,” explains Salucci. "It is a very strong effect that cannot be explained trivially using the Standard Model of particles." The Standard Model explains how the basic building blocks of matter interact through three fundamental forces, the...

New research questions the rate at which the Universe is expanding
... that the universe is dominated by "dark energy" that behaves like a cosmological constant - this is now the "standard model" of cosmology,” said Sarkar. “'However, there now exists a much bigger database of supernovae on which to perform rigorous...

New physics needed to explain early expansion of the Universe
... that extra physics are needed to reconcile the duo’s data with what has become expected according to standard model of cosmology. “One of the possible solutions would be to invoke an evolving dark energy, with a density that increases as time...

Most accurate measurement of Universe's dark matter revealed by DES survey
... Risa Wechsler, a founding member of DES. Astrophysicists need precise tests of the standard model of the Universe because its ingredients are not completely certain. The model – called Lambda-CDM – includes two key ingredients; cold dark matter...

The Global Space Governance Study – A new regulatory framework for New Space?
... of substantive technical, operational, and economic challenges. We will then consider what types of regulatory frameworks, standards, model national laws, or sanctioned demonstrations can promote and benefit new space activities, but in a structured...

An alternative model for pulsars and spiral galaxies
... others can manifest significant changes to their pulse profile; these facts also present challenges for the standard model, as there is no very obvious reason why the emission should vary in these systematic ways. Spiral galaxies are...
