We won't get to see it.
BTW, last big time global civilization ending deal was in 535AD. St. Gildas was on his way back to Britain from Rome when something happened that actually had stone buildings flying apart up into the sky, with human beings and animals being tossed all over the place, up, down, over there, back here ~ and so forth.
English analysts have always interpreted the situation as one of the Saxons burning down buildings as they invaded Britain.
Don't believe the Saxons were involved in anything that year ~ it was really bad, and afterward much of Europe and Central Asia had nearly 1000 years of Dark Ages. China was out of commission for 300 years!
According to the Annals of the Kings, Arthur was concerned because it was difficult to make out what the big red thing in the sky was all about!
I doubt it will be any better next time.
You’d likely enjoy Game Of Thrones if the sometimes very adult content doesn’t put you off. It’s come close for me on a few occasions. There’s a red comet that appears in season two.
