Our present understanding of the Universe is shaped by cosmological observations. Based on a model (built with well established theories + certain supporting assumptions) we...
(A desperate attempt at explaining infinity in finite terms…) 1 Einstein and the cosmological constant I invite the nonexpert reader to a short but intense...
Yes, I have asked the question: what if the most widely recognized physicist ever was actually wrong? Perhaps wrong is too hard of a word,...
We have converted our galaxy into an enormous antenna. Then, we have used that antenna to detect the gravitational wave background generated by the merger...
Cosmology has been developed for thousands of years and there have been dozens of theories proposedto describe the observable universe. Starting from the Babylonian cosmology...
Recently, at the end of a yoga class, the teacher talked about balance between unchanging and transient states. It could not relate more to what...
A flash in the sky. With such high energy that our eyes cannot detect it, as it is outside of their electromagnetic range. But gamma-ray...
These are interesting times for cosmologists. On the one hand, general relativity and the cosmological principle of homogeneity and isotropy on sufficiently large scales has...
The field of cosmology appears to be in flux. The standard model ΛCDM, which is based on the cosmological constant Λ and cold dark matter...
Einstein’s theory of General Relativity (GR) has not only changed our view on gravity but also had deep impact on the construction of modern physical...
