Him: So, you are saying, no supernova warning is possible? Even if we had a probe near every suspicious star nearby, the signal from the probe wouldn’t be here before the gamma rays?
Me: Actually, I am not saying that. I am saying that we could predict for every nearby star, when it is its time to go off. Some big telescopes and computers, is all we need for the stellar weather predictions.
Him: It’s not what I hear from others. They say it’s impossible. The light speed prevents any kind of warning.
Me: No, it doesn’t. You can’t get the news of a storm from the other side of the planet in less than a millisecond. However, you can predict it hours ahead. The same principle applies here.
Him: I see.
Me: But you know me, I think we should dismantle every star, anyway.
Him: Yeah, yeah, here you go again …
