When Columbus sailed to America in 1776 Didn't he sail to America in 1492?

@(Uncle Jeff) Kamiokande detected just [11 neutrinos](http://www-sk.icrr.u-tokyo.ac.jp/sk/news/2017/02/SN1987A-en.html) from SN1987A. Its successor, Super-Kamiokande, is expected to detect [~8,000 neutrinos](http://www-sk.icrr.u-tokyo.ac.jp/sk/sk/supernova-e.html) from a core-collapse supernova distant ~10 kpc. Next-generation experiments, like Hyper-Kamiokande, will be able to detect [50,000 neutrinos](http://www.hyper-k.org/en/physics/phys-neutrino.html) from a similar event. Also, there is an international warning system ([SNEWS](https://snews.bnl.go...

@moderators, considering the recent unfortunate 2,349 deaths in 24h, I fear the question risk to be outdated before going live and resolve ambiguous.
