Results of laboratory studies of hydrogen-induced redshift indicate light is shifted spectrally as found in space.[1] Due to improvement in telescopic equipment, vast regions of hydrogen in and around galaxies are now being found, the necessary ingredient for redshift. If this is the cause of the cosmological redshift, then a universe exists that is not expanding, and there was no big bang. This is an effort to compare the big bang model (BBM) to a great age model (GAM). Approximate distances and ages can still be determined based on amounts of red shift currently seen. Size of the universe might be much larger than currently thought. With a GAM, inflation and dark energy are not needed. GAM allows sufficient time for stars to have full life cycles. This process involves their birth, consumption of all their fuel, then cooling to the point of non-visibility naturally resulting in many times more cool or invisible stars than bright ones. (The PIR acronym in the following refers to Plasma-Induced Redshift, also known as New Tired Light, NTL. It is referred to above as hydrogen-induced redshift)
