Most likely has already happened. It’s like us getting the local news delayed 100,000 years.
This is why I see most astronomical efforts - beyond our solar system - as perhaps interesting but otherwise a huge waste of time and money. Those ‘fantastic,’ human-colored images of the cosmos taken by Hubble and now by James Webb after thousands or millions of years of delay, are, in any practical sense, no more than pretty pictures for my wall.
One exception could be finding that Earth-killing asteroid soon enough to call Bruce Willis to save us.
This is not to disparage your efforts, sir, in presenting such information to interested parties.

The point is, pure research has to be done all the time in order to even become aware of such things. If we already knew everything -- and we never will -- there'd be nothing else to know, and in examples like that one, nothing to worry about. The threat of big impacts was whistled past many a graveyard until the 1994 SL-9 impacts on Jupiter, and that was not even 30 years ago. Doubting the possibility now seems absurd -- the fact is, it was absurd before.
