Gravitational repulsion (Antigravity) and attraction, and fundamental concepts of energy propagation (Intrinsic Spin – ISpin model) are Dr. C. K. Gamini Piyadasa’s current research interests.  His research in both the fields have yielded promising results, giving rise to recent publications in: gravitational repulsion and attraction, and energy propagation in free space.  In combination, these findings lead to the Unified Field Theory (UFT) envisioned by Dr. Albert Einstein.

Having started his research carrier in Atmospheric and Thunderstorm Physics, by 1990, Gamini observed many anomalies in present understandings.  One was a major foundation in science on propagation and nature of energy in universe.  Conducting research on that, he published experimentally proven demonstratable properties of wave nature by interference and diffraction (opposed to the theoretically derived Fresnel-Fraunhofer diffraction principle).  A new interpretation by Gamini to the famous Youngs’ Double Slit Interference has led to the new pathway to understanding the nature of energy propagation; based on which, Gamini experimentally developed the ISpin theory.  Applying the concept of “ISpin” model, he subsequently published the refined version of Energy Propagation as: “The heuristic model of energy propagation in free space, based on the detection of a current induced in a conductor inside a continuously covered conducting enclosure by an external radio-frequency source”.

By 2009, Gamini’s series of experiments in atmospheric physics led to revealing insights of gravitational repulsion in numerous phenomena both in the laboratory environment and in the nature.  The experiments are proving that almost all macroscopic and microscopic phenomena that we experience in nature are governed by the two forces gravitational repulsion and attraction.

Gamini is an instrumentalist and an experimentalist, who obtained his PhD from University of Colombo, Sri Lanka, in collaboration with Uppsala University, Uppsala, Sweden.  In the PhD research programme focused on development of Mass Spectrometry techniques, he revolutionised by demonstrating world’s highest Time-of-Flight (ToF) resolution adapting linear successive reflection of molecular ions and other improved mass spectrometry techniques.

The patent US-6,489,610 B was obtained by Gamini for improved mass selection technique in the ToF Mass Spectrometer, which has greatly pushed up the standard limits by 20-fold; going against/challenging the existing theories.  The instrument which significantly changed the single mass selection resolution in Time-of-Flight (ToF) Mass Spectrometry is still being manufactured by Thermo Fisher Scientific – Applied Biosystems, and is one of the essential tools in protein characterisation.

Gamini’s passion is to pursue results that are: closer to experience, experimentally proven, demonstratable and generalisable across various contexts.  His presentations are always based on experimentally verified data (not theoretical visualisations) and conclusions that can be reached by any layman who is curious about nature.  He has published research publications on different disciplines in Physics and Engineering; viz. mass spectrometry techniques, Interference and Diffraction Optics, Electromagnetism, Antigravity and Power System Engineering.

Gamini has received an array of awards and grants:

  • International Invention Award Switzerland
  • Presidential Award Sri Lanka
  • Fellowship NSF, National Science Foundation Sri Lanka
  • Sweden Uppsala University Carl Tryggers Fellowship 2001/02
  • University of Manitoba Grant National Science and Engineering Research Council of Canada (NSERC) 2003/06 – 2011/14

Gamini’s life’s purpose is to contribute something to the knowledge of the world, by critically viewing natural phenomena.  He pursues hobbies of loving animals and nature.  Helping others makes him happy.
