LOG#150. Bohr and Doctor Who: A=mc³.

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

LOG#133. Spacetime foam(III).

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

LOG#132. Spacetime foam(II).

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

LOG#128. A chaosmic TSOR returns.

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

LOG#115. Bohr’s legacy (III).

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

LOG#077. Entropic electrogravity.

Tower Wang, in his paper Coulomb Force as an Entropic Force, deduced Coulomb and Newton laws using the Verlinde approach in D=3+1 dimensions. He begins with the Reissner-Nordstrom metric in D=4 spacetime: with the function and He introduces a “geometrized” … Continue reading

LOG#070. Natural Units.

Happy New Year 2013 to everyone and everywhere! Let me apologize, first of all, by my absence… I have been busy, trying to find my path and way in my field, and I am busy yet, but finally I could … Continue reading

LOG#031. Entropic Gravity (II).

We will generalize the entropic gravity approach to include higher dimensions in this post. The keypoint from this theory of entropic gravity, according to Erik Verlinde, is that gravity does not exist as “fundamental” force and it is a derived … Continue reading

LOG#030. Entropic Gravity (I).

In 2010, Erik Verlinde made himself famous once again. Erik Verlinde is a theoretical physicist who has made some contributions to String Theory. In particular, the so-called Verlinde formula. However, this time was not apparently a contribution related to string … Continue reading
