B.G.Sidharth, Ph.D.,F.R.A.S., Knight Commander Star Italian Solidarity, Doc.Phil(Hon) is the founding Director of the renowned B.M.Birla Science Centre, Hyderabad and its subsidiary centres like the G.P.Birla Observatory & Astronomical Research Centre. Here is how his research work on Particle Physics and Cosmology has been described , a striking feature of which is its strong interface with experiment and observation :He has been nominated for the highest physics award.
In the mid nineties his work on 1D and 2 D behaviour of Fermions and Bosons (e.g., Journal of Statistical Physiscs, 1995, v.3/4. 1998 amd other papers ) predicted the behavior in nano-tubes and graphene(this latter by a decade). The Nobel prize was given for the experimental discovery of grapheme to Profs. Geime and Novosolev. As Nobel Laureate Prof.Claude Cohen-Tannoudji observed, about Sidharth’s work,“ ..it is ofcourse clear that you have done important work on 1D and 2D fermion systems”

In 1997, when the standard big bang model was the accepted theory, with the Universe believed to be slowing down to a halt due to dark matter B.G.Sidharth put forward his dark energy driven accelerating universe cosmology, with a small cosmological constant. Moreover all the supposedly accidental Large Number relations were now deduced from theory, rather than being adhoc ( “The Universe of Fluctuations”, International Journal of Modern Physics A, accepted April 1997). These relations have been an enigma for nearly a century. This contra prediction was confirmed by observation the very next year. Today dark energy is the new paradigm and the 2011 Nobel Prize in Physics went to the Observational Evidence for all this, done in 1998.
Commenting on this, a very reputed publication noted :’… It is of course clear that your equation predicts an exponential (inflation-type) expansion of the current universe, hence acceleration. And it would have been nice if the Nobel committee had mentioned this," Sir Anthony James Leggett, also known as Prof Tony Leggett of the University of Illinois, a Nobel Prize winner in physics in 2003, wrote in his e-mail to Sidharth.Prof Antony Hewish, a British astronomer who had won the Nobel for physics in 1974, also felt that Sidharth's work should have been recognised. "You must feel gratified that your ideas in 1997 were spot on," Hewish wrote.’
“..I would guess that while you did not share the prize this year,  the fact that 
you predicted something that was the key to the others getting the prize should make your chances
quite high for the future.” wrote another Nobel Laureate.

Another Nobel Laureate noted “…I certainly do appreciate that you are one of the very few to have recognized,on theoretical grounds,the possible need to reintroduce a nonzero cosmological constant ahead of the supernova experiments!

In the mid nineties he also put forward a theory for 2 and 1 dimensional Fermions in several papers predicting the behavior in one dimensional  nanotubes and also grapheme
The latter was experimentally observed in grapheme around 2005, a discovery that lead to the Nobel Prize for the experimentalists.

This was but a part of Sidharth’s work using fuzzy noncommutative spacetime. This is a new paradigm which breaks with a century of work that culminated in General Relativity and Quantum Field Theory, both of which are rooted in a differentiable space time. Sidharth’s new ideas, set against the backdrop of oscillators at the Planck scale set in dark energy, bring out hitherto unsuspected and deep properties of what may be called fermionic spacetime, the previous theories being based on bosonic spacetime. This work, which throws up Planck oscillators as a universal algorithm,makes physics less reductionist and more thermodynamic. It is a paradigm shift vis a vis twentieth century physics that brings in a reconciliation between gravitation and Quantum theory,(though not the full General relativity) Pleasingly there is a smooth limit from these ideas to the older theory, when the square of a typical Compton wave length (including the Planck length as a special case) is neglected. At the same time results of all this work are experimentally verifiable and indeed many have since been verified.
Several significant consequences and new avenues have been opened up as a result .. Some of these are :
1. Apart from the cosmic acceleration another footprint of his zero point dark energy model of 1997 is a cosmic background radiowave background in the rough waverlength band of of some tens of centimeters which has been detected in recent years particularly by NASA’s ARCADE Balloon experiment
2. His Pion Model generates a mass spectrum relation for all known elementary particles, based on interquark dynamics. This simple formula gives all masses with an error of about 3 percent to less than one percent. Subsequently detected DS2731 and the possible pentaquark too are included. Many more are predicted.
3. A residual energy in the universe that is 10^(-33) eV is deduced – indeed this too has been confirmed by an analysis of WMAP data. It is otherwise mysterious and inexplicable.
4.A variation of G with time is predicted, which is within experimental limits and via this mechanism all the stand effects of General relativity like the bending of light and the precession of the perihelion of the planet Mercury etc. are explained as also the shortening of the time period of binary pulsars. Further more there is an explanation for the otherwise inexplicable anomalous acceleration of the Pioneer space crafts. New effects too are predicted, e.g. a slight change in orbital parameters of planets.
5. The fuzzy spacetime modifies the usual energy momentum dispersion formula of special relativity, leading to the so called Snyder-Sidharth Hamiltonian and further to the modification of the Dirac equation at ultra high energies with the inclusion of an extra parity violating term. All this work shows how the neutrino gets mass as also leads to the possibility of ultrafast fermions decaying in the manner of weak interactions.
6. The above effects also show that the special relativistic GZK cutoff is violated – preliminary evidence from Ultra High Energy Cosmic Rays is already pointing in this direction.
7. In the resulting extended non Abelian gauge description, not only can gravitation be accommodated, but there is also a mass generation mechanism which gives a geometrical underpinning to  the Higgs mechanism.
8. Indeed the work devalues Gravitation to the level of a residual energy ( a la Sakharov), and thus provides an answer to the question, Why has nearly a century of work on unifying Gravitation with Electromagnetism ( or Quantum Theory and General Relativity) failed?
9. His work predicts a tiny mass for the photon, well withing experimental limits. There is observational evidence for exactly this value of the mass, most recently in the observations of blazars by the Magic telescope team.
10. There is also a characterization of gravitation that resolves the longstanding puzzle of the Weinberg formula : Why microphysical constants should depend on cosmological parameters.
11. His characterization of anti-particles/anti-matter in terms of symmetries of high energy negative energy solutions treats the Compton scale as a Quantum Mechanical counterpart of the Einstein-Rosen bridge and predicts a new interaction at these ultra high energies, mediated by vector bosons, one that is  shortlived .This work also predicts that particles and their anti-particles have slightly different masses. Interestingly, hints for both these predictions has been found, the latest by the CDF team in Fermilab
12. His work on Black Holes deduces that if at all Black Holes exist, they will be only the supermassive ones.
13. Similarly his wor showed that there was no need for the Higgs Boson – there is an alternative  explanation for this. Both these are now being hinted at.
And so on.
Sidharth’s work has been published as over one hundred and fifty papers in peer reviewed international journals, as also in four books, The Chaotic Universe (Nova Science, New York, 2001), The Universe of Fluctuations, ( Springer, Netherlands 2005) ,The Thermodynamic Universe , (World Scientific, Singapore, 2008) and a fourth non-technical book, When the Universe Took a U turn ( World Scientific, Singapore, 2009).
These apart he has co-authored, edited several books published by American Institute of Physics, Kluwer, Springer etc.
 Comments on his work :
“…You are one of the greatest physicists of our modern time and I have a very high regard for your scholarship ..”. Member of the Royal Swedish Academy of Sciences.
“ Dr.Sidharth is one of the greatest living physicists because of his ability to think out of the box” Prof.C.Corda, Chairman Inst of Adv.Math & Theo.Physics, Prato-Florence.
 Prof.A.Kholodenko of U.S wrote, “.. your interpretation of the QCD generated mass spectrum is absolutely astonishing…(your results) are of central importance…”
The work has been described by Prof. L.Nottale ,Director, Research, CNRS ,France as important and constituting breakthroughs. According to a prominent Editor-in-chief of a very prestigious journal, the work will get the highest distinctions available for Theoretical Physics,or is much admired in the words of Prof.John Madore.Another reviewer wrote, “ During the last years Dr.Sidharth has devoted his investigations in very interesting and important aspects of Fundamental Physics and has brought to light intriguing features of the nature of the Universe …” , while Dr.John Hartnett of Australia calls this work” excellent”.Nobel Laureate Prof.I.Prigogine described the work as “Very interesting” and, “ I agree with you that spacetime has a stochastic underpinning.” In the words of the famous physicist, P.T.Landsberg, “ I found your work most engrossing and there is much there which I should like to learn about…to read these chapters was a stimulating experience…” Yet another reviewer described his work as “unique” Dr.O.Doctorow characterizes Sidharth as “ a creative genius and nonconformist” while according to Prof.Walter Greiner while the papers are sometimes on the short side, each one carries a very novel and innovative idea. Robert Paster, in his 2006 book, New Physics and the Mind, devotes an entire Chapter to this work and notes, “ Sidharth’s work…. is of great intellectual breadth and depth..” The editor of the Journal of Cosmology has described him as “ best amongst the best”
