Are diamonds and other (crystalline) jewels/gemstones forever? Well, if protons are stable they are. If not, you are lost! We are all lost indeed in such a case…(However, I am sure that Superman would be fine to know the fact … Continue reading

This post is the first of three dedicated to some of my followers. Those readers from Mexico (a nice country, despite the issues and particularities it has, as the one I live in…), ;). Why? Well, …Firstly, they have proved … Continue reading

Hi, folks! Before the upcoming series of thematic blog posts (they are on their way, eager readers), I found a very interesting paper to discuss. The paper is this http://arxiv.org/abs/1408.1820 and the pdf file can be found here http://arxiv.org/pdf/1408.1820v1.pdf . The author of the … Continue reading

The year 2013 is coming to its end…And I have a final gift for you. An impossible post! This year was the Bohr model 100th anniversary. I have talked about this subject already, here, here and here. The hydrogen spectrum is very important in Astronomy, … Continue reading

Some conclusions of this fascinating subject and thread about the mythical spacetime foam: (1) CDM(Cold Dark Matter) and MOND seems to be complementary descriptions of the same dynamics and phenomenology. (2) MOND force law works at galactic scales. This can … 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

Some weeks ago, I was studying some papers and talks by Jack Ng. I am going to share with you what I have learned from them, about the wonderful subject of the “quantum spacetime foam”. Some topics and ideas I … Continue reading

Dedicated to Niels Bohr and his atomic model (1913-2013) 3rd part: From gravatoms to dark matter Gravatoms Imagine a proton an an electron were bound together in a hydrogen atom by gravitational forces and not by electric forces. We have … Continue reading

The last of my three posts tonight is a mysterious dual system of units developed my rival blog (in Spanish language mainly): http://tardigrados.wordpress.com/ His author launched an interesting but speculative dual system of units in which every physical quantity seems … Continue reading

The second paper I am going to discuss today is this one: http://inspirehep.net/record/844954?ln=en In Note on the natural system of units, Sudarshan, Boya and Rivera introduce a new kind of “fundamental system of units”, that we could call G2 system … Continue reading
