Milky Way’s mysterious haze

Researchers have just discovered a mysterious “humming” in the core of our galaxy: the Milky Way emits an important amount of microwave radiation, and its origin remains unknown. New cold gas clouds of carbon monoxide have also been discovered, helping astronomers locating star-forming regions.
The main objective of the Planck satellite, …

Testing loop quantum gravity

One of the challenges of modern physics is to reconcile quantum mechanics and relativity. So far, quantum theories of gravity have never been tested experimentally. Loop quantum gravity, one of these theories, might be testable after all.
The key to this experimental test comes from black holes: when they evaporate, the …

Observing the Multiverse

Our Universe is big, really big… And it might not be the only one. Various theories predict the existence of other “bubble universes”, and some of them should occasionally collide. These collisions could be the key to confirming the existence of the multiverse.
Theoretically, the collision of two bubble universes produces …

The best alternative to dark matter and dark energy?

According to the standard model of cosmology, also known as ΛCDM (Lambda Cold Dark Matter) model, about 95% of our Universe is invisible or undetectable, or possibly both. Various alternative models have been proposed to describe our Universe without the need of dark matter or dark energy. One of them, …

Cosmology – A brief review of the standard model

Cosmology, the study of the evolution and the structure of the Universe, has a long history in various areas, such as philosophy and of course science.
I recently found this paper by Jorge L. Cervantes-Cota and George Smoot on arXiv, and thought some of you might be interested. It gives a short review on …
