Ask the string theorists.

Im agnostic until we have very tiny microscopes.

Until then we are stuck at a funky high level abstraction. The table of quarks and particles we have is like what would happen if we were trying to figure out what our computers were made of by interacting with a url bar, and coming to the conclusion that the fundamental components of a computer are like... a table of HTTP response status codes.

Not to say that its useless, just that its not zoomed in enough.
