Cosmology is facing again some troubles. Some estimations of the Hubble parameter differ up to four standard deviations from the accepted value. Even when a few km/s/Mpc are not quite a huge difference, it turns than they can provide anomalies … Continue reading
The spectrum of gravitational waves!!!!! Purely gravitational wave music! The blog post today will cover two topics from elementary viewpoints: falling into a non-rotating black hole and gravitational wave “music”, i.e., gravitational wave formulae! It is a hard equilibrium … Continue reading
The second post in this thread is completely speculative. 1) Suppose that Dark Energy is some kind of “fluid” made of some long wavelength “particles” or “exotic stuff”. 2) How different are those “Dark Energy particles” from the particles we … Continue reading
Dear followers and dear readers! Time has come! I am back with the brand new TSOR and its new site. The wait is over. :). Firstly, I have some interesting things to tell you: 1) I have not finished the … Continue reading
This new post ignites a new thread. Subject: the Science of Neutrinos. Something I usually call Neutrinology. I am sure you will enjoy it, since I will keep it elementary (even if I discuss some more advanced topics at some … Continue reading
The current Universe has evolved since its early phase of thermal equilibrium until the present state. The departure from thermal equilibrium in the early Universe made a fossil record we can observe at current time! There are some easy rules … Continue reading
The next thread is devoted to Cosmology. I will intend to be clear and simple about equations and principles of current Cosmology with a General Relativity background. First of all…I will review the basic concepts of natural units I am … Continue reading
The topic today is to review a beautiful paper and to discuss its relevance for theoretical physics. The paper is: Comment on the cosmological constant and a gravitational alpha by R.J.Adler. You can read it here: http://arxiv.org/abs/1110.3358 One of the … Continue reading
