What Happens When Betelgeuse Explodes?
StartsWithABang writes: One of the great, catastrophic truths of the Universe is that everything has an expiration date. And this includes every single point of light in the entire sky. The most massive stars will die in a spectacular supernova explosion when their final stage of core fuel runs out. At only an estimated 600 light years distant, Betelgeuse is one (along with Antares) of the closest red supergiants to us, and it's estimated to have only perhaps 100,000 years until it reaches the end of its life. Here's the story on what we can expect to see (and feel) on Earth when Betelgeuse explodes.
The Club of Rome said total collapse 2040-ish.
Even if they have, so what? There's two things to note. They've been wrong before.
And second, total collapse isn't going to impact the developed world like it will the worst off parts of the world. Places like Africa or Asia would be hit far harder than places like North America or Europe. This is quite relevant because those are also the places causing most of the overpopulation problem in the first place.
This is one of the ugly facts about overpopulation that groups like the Club of Rome tend to gloss over. Population growth is only happening in certain locations. And since the consequences of population growth also will happen in those same locations, it gives a strong disincentive to care if the shit hits the fan. We aren't all in this together.
My point behind this is to point out what should be obvious. The developing world has the overpopulation problem and has the extreme vulnerability to global trade collapse. Meanwhile the developed world has fixed its shit more or less. Sure there's a few Californias and Greeces out there, but for the most part, the developed world is going to weather any "total collapse".
The Club of Rome is all set to blame the people who aren't causing the problems. Why? Because that's where the money is.
I look at the sky every night, knowing the light is hundreds of years old. Half of the stars might have gone supernova already.
The life cycle of even the largest stars is still in the 10-100 million year range. The chance that one of them has exploded in the last few hundred years is tiny. Galaxy-wide we expect one supernova roughly every century so, unless you get really lucky, practically every star you can see with the naked eye has an extremely good chance of still being there...even Betelgeuse which they estimate has a 100k year lifespan remaining and is only 600 light years away. Of course if you had RTFA you would have known most of this...hope you appreciate the irony!
