Basic Techniques and their Limitationselativistic particles. Neutrinos and gravitational waves propagate like light rays. But the low sensitivity of the corresponding detectors makes it impossible to observe high-redshift sources of neutrinos and gravitational waves.

The Past and the Futurewas transparent to light. Fortunately this was the case during more than 99.99% of the age of the universe. Only during the first about 380 000 years (corresponding to redshifts . > 1090) the expanding universe was (due to the high free-electron density) opaque to light of all wavelengths.

Today the high-redshift galaxies have developed into one of the important topics of astrophysics, accounting for about 5–10% of the publications in the major scienti?
