Theoretically, the collision of two bubble universes produces …
The cosmological principle is a fundamental notion of modern cosmology. In a few words, our position in the Universe has nothing special: wherever you are in the Universe, when you observe it, what you see is the same everywhere, and the laws of physics are the same everywhere. The Universe …
As most of you have probably already noticed, I am not particularly fond of the standard model of cosmology… More precisely, I have a problem with dark matter and dark energy, what I call the “dark side” of the Universe. Many times, I was asked why, so I will give …
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 …
Researchers have found that the Universe appears to be clumpier than predicted. This clumpiness, if not due to systematics, might be evidence that the standard model of cosmology needs to be rewritten.
Imagine yourself leaving Earth and looking at it as you are going further and further. You would first see …
