Was the last SN visible in our galaxy not 1604 (so Cassiopeia A doesn't count) - we're due another event and if Betelgeuse wins out over Eta Carinae in their race to the finish it would be typically spectacular.
Could of course be that the squid-like inhabitants of the Betelgeuse system had found to their cost that their efforts to build a Dyson sphere around the star to meet their burgeoning energy requirements had backfired, the exotic materials used having turned out to be extreme neutrino reflectors which had properly thrown a spanner in the star's workings and caused squidropogenic stellar change and a subsequent supernova, although at the time of the event there were probably quite a few of them claiming vociferously that it was all perfectly natural and there was nothing to worry about - one 'turbosquid' of the Betelgeuse Dyson Sphere Corporation being one of the most prolific.

Odd that you would be so triggered by some whimsy about some hypothetical squids, and odder still that you would claim the moral high ground over littering threads with argumentative dross. I might be guilty of such in this instance, but on aggregate I'm well below the noise floor compared to your efforts.
Odd, that's sad. My point was about the SN,what was your point about? The star prompted similar thoughts to now previously, dimming in 2019/2020. It's not clear why pointing out that we would be fortunate to see the event in our lifetime would trigger such a response, would you agree we'd be fortunate overall? It's far enough away to have few downsides.

To get on track, if this does go pop and due to this a whole bunch of nasties are ejected in all directions (radiation has been mentioned previously in the thread) would the light and radiation hit us at the same time? In short, does radiation have mass which means it'll reach us after the light, or not, which means we'll get hit by it at the same as we see the event?

My son is in the author list of that paper
Congrats to your son 
Long ago it was the theoretical side of SN events which occupied my time, back in the days when Chandrasekhar and Gursky were around, they may have been names featuring in your son's doctoral litsearch. It was also the time when the linked area of neutrino astronomy was really taking off, and the presence of Hawking attracted many distinguished speakers to DAMTP on both themes. Before the computerised voice arrived, Prof H would ask a question and have it translated for the speaker by a PhD student, a remarkable ability on both sides.
The science has moved on, so have people. My activity shifted later to participating in SN searching alongside better known UK patrollers using our own kit and our own time, including my friend and colleague the late Ron Arbour who was prolific. All I managed was to contribute data to the light curves of some extragalactic SN in the 80s and early 90s.
All the best to your son, being at the cutting edge these days has to be tremendously fulfilling.
I've used the OT icon as a safety net, hopefully this post won't trigger more so-called "whimsy" given it's about people and not directly about Betelgeuse

Prediction - you will need to have had your soul ported over to a metal robot in order to see this explode.

The last calculations I saw reckoned it would appear as bright as the gibbous moon, with the light concentrated at a point source; quite a sight.

is that when we all get superpowers?
