Research Interests

Although experimental results compel me to accept that modern physics is very successful in its area of application, I do not believe that it is the final answer regarding the fundamental workings of the universe. I believe the key lies in a gravitational repulsion of matter and antimatter, and I'm willing to take the risks involved in investigating that possibility to its fullest extent.

In my interdisciplinary PhD project I have developed a formal axiomatic system with a physical interpretation that can potentially be applied as a foundational framework for physics under the condition that massive antiparticles are repulsed by the gravitational field of massive particles of ordinary matter. The ‘Elementary Process Theory’ (EPT) is then a collection of seven elementary process-physical principles, each of which is mathematically expressed by a non-logical axiom of the axiomatic system: these describe, without reference to any coordinate system of an observer, the elementary processes at supersmall scale by which fundamental interactions have to take place for repulsive gravity to exist — it follows that these processes are in essence all the same, regardless of the type of interaction that takes place.

My main research interest is to prove that the four fundamental interactions (gravitational, electromagnetic, strong, and weak) as we know them can take place in the processes described by the EPT. The first question, however, is how to prove that. This is not at all straightforward: given the degree of abstractness of the EPT, it cannot be shown by means of a so-called direct proof that any of the modern interaction theories emerges from the EPT. But I did develop a suitable method: the EPT agrees with the knowledge that derives from the successful predictions of interaction theory T if and only if the EPT has a model M that reduces empirically to T — that is, if and only if for every experiment that has confirmed a prediction of T, the outcome can be described as a prediction of M. Existing knowledge of an interaction has, thus, to be incorporated in a model of the EPT: a negative result is then that no such model exists.

Recently, I have applied this method to show that the EPT agrees with Special Relativity (SR): I have fully specified a model of the EPT that incorporates SR. This model is, in fact, a category consisting of I am now working on a (categorical) model of the EPT that reduces empirically to General Relativity (GR). In other words, I am now working on a model of an elementary process by which a gravitational interaction takes place, such that the model on the one hand predicts matter-antimatter repulsive gravity, yet on the other hand reproduces the successful predictions of GR. Although details of that model remain to be specified, it is already clear how to proceed from there towards a quantum theory of gravity.
