Two Bangladeshi scientists at an international seminar at Rajshahi University yesterday detailed their groundbreaking claim of reconstructing the 'theory of special relativity' as well as presenting an 'alternative relativity theory', both relating to faster than light speed.

The two theories, comprising 21 equations each, define a new concept of reciprocal symmetry that attunes the theory of relativity with quantum mechanics, said the two scientists -- Dr M Osman Gani Talukder and Dr Mushfiq Ahmed, both former physics teachers of Rajshahi University.

One set of the equations including three equations by Einstein and 18 new ones complete the theory of special relativity, they said.

The other set of equations, which the physicists called non-Einsteinian relativistic case, provides an alternative relativity theory and resolves the dilemma over neutrinos faster than light speed and several problems relating to cosmological theories.

"Lorentz and Einstein gave a transformation law for the relativistic addition of velocities only. We have found the relativistic addition laws for all other relativistic quantities of time, mass, length, momentum, and energy,” Dr M Osman Gani Talukder told The Daily Star after the seminar organised by Rajshahi University in association with The Daily Star.

"Further, we have derived the multiplication rule for velocities and all other quantities. We also found the expressions of minimum and maximum values for the relativistic quantities.

"Einstein's theory gave us three equations that describe contraction of space, dilation of time and variation of mass. We have derived other equations to complete the theory as well as make it compatible with quantum mechanics that describes the behaviour of very small things, like atoms and sub-atomic particles, which was earlier incompatible with Relativity theory," he said.

Osman Gani Talukder and Mushfiq Ahmed read out papers on the first day of the seminar, which was spread over two sessions.

Talukder presented papers on 'Correspondence between Reciprocity and Discreteness' and 'Relativistic Rule of Multiplication of Velocities Consistent with LorentzEinstein Law of Addition and Derivation of the Missing Equations of Special Relativity', while Ahmed read out papers titled 'Reciprocal Symmetric Kinematics and Correspondence between Special Relativity and Quantum Mechanics' and 'Reciprocal Symmetry Quantum Statistics and Spin' in the morning session presided over by RU Vice Chancellor Prof M Abdus Sobhan.

Prof Aminul Islam of the physics department chaired the afternoon session where Talukder and Ahmed read papers titled 'Incompatibility between Einstein's Postulates and Special Theory of Relativity', 'Non-Associativity of Lorentz Transformation and Associative Reciprocal Symmetric Transformation', 'Derivation of the Missing Equations of Special Relativity from de-Broglie's Matter Wave Concept and the Correspondence between them' and 'Derivation of Non-Einsteinian Relativistic Equations from Momentum Conservation Law'.

Earlier in the morning, Prof M Abdus Sobhan inaugurated the seminar on 'Special Relativity' at RU Senate Bhaban. Around 150 physicists from home and abroad took part in the seminar.

Talukder and Ahmed will lecture on two more topics to substantiate their claims on the second day of the seminar today.

Prof Hartmut Baerwolff of University of Applied Sciences, Cologne, Germany, will preside over the session.
