fundamental level of existence in Buddhism

After long time and back to BSE. My question is; according to science all the existence are sequenced as matter made of alchemy (chemistry) , molecules , atoms, sub particles then energy. I think base of science is depend on this sequencing and it is considered as a reality. However science possesses its own controversies as unable to provide proper explanations as result of limitations of five senses and their extensions.(e.g...eye and hi tech microscopes) i think science stuck at "energy" in sequencing the subtle level of existence. but it is so clear what have found up this level of scientific finding.science came across massive breakthroughs such as finding of atom, artificial memory, artificial intelligence , MRI etc...and science based on proofs. at the subtle level science manipulate energy at best level becomes it can do everything as "energy is everything" including our mind. Think I've made concise explanation of what science can do if i am not mistaken. Now we turn towards the Buddhism as a great philosophy. Can Buddhism provide concrete explanations on above questions? what is the absolute, final, subtle level of existence? how is energy defined in Buddhism? Is there anything beyond energy? If there are, what is the proof?
