We show that present day observational techniques make it possible to detect diffuse gas masses down to ∼1010M in cosmic voids with linear sizes of ∼1 Mpc or larger. The observations consist of searches for absorption lines, similar in character to those produced in galactic interstellar clouds, in the spectra of high-redshift objects located beyond previously identified voids adjoining nearby superclusters.
