If something hat has no volume and no mass can exist ,what does it mean to say that something physical exists?
 
Physics news on Phys.org
Sorry about the tablet problems (somt in the title and "hat" not "that")
 
I am referring to point and massless particles
 
This is a philosophical question (ontology). Please review the forum rules on philosophy.
