I studied astronomy at the state university of Groningen, The Netherlands. Although I didn't start a career in science, I still try to keep up with all the exciting things that happen in physics and astronomy.
In the course of the years I have had quite a number of ideas on what energy, force and matter really are and how the universe came into existence. I have bundled all these ideas in the document Energy_force_and_matter.
I welcome comments on the various ideas in my document by scientific specialists in those areas. My contact details are here.
