Richard Haney raises the question as to whether spacetime could be
discrete.  I am not sure what this means, but if it means that there is
a minimum length, this appear inconsistent with special relativity. 
Could somebody elucidate this point?

"One has to find a possibility to avoid the continuum (together with
space and time) altogether. But I have not the slightest ideas what kind
of elementary concepts could be used in such a theory."
