Escaping the dark side

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 …

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, …

Matter and antimatter – A fundamental symmetry confirmed

According to theory, matter and antimatter have exactly the same properties, except for the opposite electrical charge. Researchers have now calculated the antiproton mass relative to the electron with unprecedented precision: it weighs exactly the same as its matter counterpart, the proton.
The laws of nature are assumed to obey a …

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 …

Quantum nature of space challenged by observations

New observations have shown that the quantum structure of space, if there is any, is at much smaller scales than predicted.
In Einstein’s theory of relativity, space is a smooth, continuous fabric. In quantum theory, there is an inherent discreteness present in physics. In an attempt to reconcile the two theories, …
