  The present common view about GRB origin is related to cosmology, what is
based on statistical analysis, and on measurements of the redshifts in the GRB
optical afterglows of long GRB. No correlation is found between redshifts, GRB
spectrum, and total GRB fluence. Comparison of KONUS and BATSE data about
statistics and hard X-ray lines is done, and some differences are noted. Hard
gamma-ray afterglows, prompt optical spectra, hard X-ray lines measurements
could be important for farther insight into GRB origin. Possible possible
connection of short GRB with soft gamma repeaters is discussed.
