Limits are imposed upon the possible rate of change of extra spatial dimensions in Kaluza-Klein and superstring theories by considering the consequences of such changes for primordial nucleosynthesis and the positioning of nuclear resonance levels in samarium, carbon, and oxygen. Previous limits from nucleosynthesis had not included strong-interaction… CONTINUE READING
