Thanks so much @organduo, I really appreciate your response :-) And I don't know the answer to your question. When Greek philosophers thought of the idea that everything is made up of tiny, indivisible particles they didn't know it would take several centuries before the atom was discovered in real life. On the other hand, developments withing science do seem to accelerate a lot since the 20th century. So, maybe next year, maybe next century, or maybe in our next life... who's to say? ;-)
