Some time ago, Zeldovich derived the following expression for the vacuum energy density: (1) or equivalently, with a link to Caianiello’s maximal acceleration formula, (2) Remark: the above vacuum energy density is related to the cosmological constant via … Continue reading

Preface (by the webpage master administrator, Amarashiki): This is the first invited post here, at TSOR. It has been written by Alejandro Rivero, a bright non-standard theoretical physicist out there (you can follow him at https://twitter.com/arivero). It has some outstanding … Continue reading

If you believe in both, relativity AND quantum mechanics, something that I presume you do due to experimental support, you are driven to admit that the speed of light is the maximal velocity (at least, the maximal 1-speed, in single … Continue reading

Hi, doctorish ladies and gentlemen! I am going to teach some bits of black hole today. For the simplest static (non-rotatory) black hole, the whole space-time is fully specified by mass , and some constants, like . The critical … Continue reading

Hello, metriplectic followers and friends! I have often written about Stoney units or Planck units in this blog. Indeed, I have a complete thread about systems of units. For Stoney and Planck units, you get some basic units of S.I. … Continue reading

The main challenge we are left to the 21st century and beyond is to unify every interaction into a single theory. Today, we have two main theories: The Standard Model, for particle physics. The cosmological Standard Model, or -CDM, as … Continue reading

Fast post! List of particles not yet confirmed or completely confirmed to exist: Preons. (“boojums” and “snarks”?) Pre-preons. Prequarks. Rishons. Subquarks. Haplons. Hexads/Hexons (and trons?). Bradyons (tardyons, ittyons). Superbradyons. Elvisebrions. Erebons. Darkons. . . -bosons, -particles. -bosons, -particles. Luxons (beyond … Continue reading

In the previous post, I reviewed very naively and shallowly some of the relationships between duality and gravity, and that from electromagnetic duality. There are many other interesting points. This post is aimed to highlight some issues and works that … Continue reading

The 2nd superstring revolution circled/circles about (electromagnetic) duality. In D=4 (or general space-time), duality transformations for the electromagnetic field strength read and for the dual field 2-curvature They are true symmetry for the Maxwell equations in vacuum, , and for … Continue reading

Hi, everyone! Today is not today. Elementary particles are known to fall in two species, taking for granted the Standard Model (SM): bosons and fermions. The SM bosons are photons, gluons, W and Z bosons and the recently found Higgs … Continue reading
