Cosmological Curvature and the Planck Scale

While reading up on anti-deSitter spaces in , I encountered the following quote attributed to Gauss by the author: “I have sometimes in jest expressed the wish that Euclidean geometry is not true. For then we would have an absolute a priori unit of measurement.” This is not just an empty wish. If quantum gravity… Continue reading Cosmological Curvature and the Planck Scale

Theoretical Physicists in India

There are many research centers and researchers in India working in hep-th (High Energy Physics, Theory), gr-qc (General Relativity/Quantum Cosmology) and quant-ph (Quantum Physics). However they are scattered all over the place and I have not been able to find a place which lists the names of places and individuals working in these fields in… Continue reading Theoretical Physicists in India


Multiverse, multiverse, where art thou?

As I understand it, the multiverse concept arises as a consequence of the standard inflationary scenario which involves one or more scalar fields “rolling down” the side of a potential hill, causing an exponential increase in the “size” of the Universe soon after the Big Bang. Now the form of the potential itself varies from… Continue reading Multiverse, multiverse, where art thou?
