The reader who sent me this link added:
“Derb—Does the pessimist in you wonder if the rest of the blast will wash the atmosphere off the earth and melt everything on the blast side? Are we the june bug observing oncoming headlights?”
[Derb] Well, as the country song says: Sometimes you’re the windshield, and sometimes you’re the bug. However, 440 million light years, while it may be “nearby” in cosmological terms, is still an awful long way away. So, no, I shall NOT be running down the basement to open my Chateau Troplong Mondot Saint-Emilion 1995 before the blast wave hits.
