Approximately 2 to 3 hours before the visible light from SN 1987A reached Earth, a burst of neutrinos was observed at 3 neutrino observatories. This is the time when the Standard Model of particle physics assumed 0 mass for neutrinos, before neutrino oscillations were discovered.
The neutron star collision in NGC 4993 in August 2017 was observed in visible, ultraviolet, infrared light, X-ray and radio telescopes, as well as gravitational wave signals at LIGO and Virgo interferometers, but 2 neutrino telescopes, IceCube (at the South Pole) and ANTARES (in the Mediterranean Sea) and 1 cosmic ray telescope in the Pierre Auger Observatory (in Argentina), did not see anything at all. This happened after the experiment results proving that neutrinos do indeed have mass.
Do you see gross contradiction between these 2 events? If neutrinos had mass as proven by neutrino oscillation, then their mass approaches infinite at near the speed of light, according to the general theory of relativity, right??
Thank you very much for your attention.

In Fermilab's YouTube video "Subatomic Stories: The amazing Higgs boson", water is not monohydrogen dioxide (HO2) but dihydrogen monoxide (H2O).
Thank you very much for your attention.
