Telescope built by Karoo locals releases data to astronomers around the world
... producing world-leading limits”. A second paper further elaborates on the implications of those upper limits for models of early universe star and galaxy formation. Nearly six years after construction began, the array stands at a total of 332...

Does the speed of light change with time?
... Planck CMB data contain evidence of a cyclical cosmology? Dark energy not required A faster speed of light in the early Universe would explain the cosmic microwave background without inflated ideas Finally, a changing speed of light would solve...

Are our ideas of Dark Matter wrong?
... as protons and neutrons like normal baryonic matter. It is thought that WIMPs were created in the very early Universe, when the universe was at very high temperature, and the number density of WIMPs was roughly equal to the number...

Massive quasars can be powered by direct collapse black holes say scientists
... for an unusual kind of black hole born extremely early in the Universe. Termed ‘direct collapse’ black holes (DCBHs), these... engines of luminous quasars found in the early epochs of the Universe. The simulations show that supermassive black holes...

New physics needed to explain early expansion of the Universe
... compared with those calculated for large scale structures such as galaxy clusters based on CMB data in the early Universe, don’t match up. And as yet, there is no way to reconcile them or make them fit. “This model is quite interesting...

As mystery of the Universe’s expansion rate widens, a simple solution is offered
... is expanding today, as we see it. The other is a prediction based on the physics of the early universe and on measurements of how fast it ought to be expanding,” explained Reiss. “If these values don't agree, there becomes a very ...
