Unless man intervenes with science and technology, there's a high probability the planet won't be around that long. Right now we're in an arm of our galaxy that isn't that crowded with stars and other cosmic stuff. Due to our solar system's rotation and other systems doing the same in about fifty thousand years we will be in a heavy traffic area.

So if man does nothing, the author's theories are crap.

Can you provide a reference? What are the implications for life in general in a denser region?

I've read that life could not exist in the core of our galaxy, but am not familiar with similar arguments (assuming they are similar) for intermediate regions of density outside the core. And extrapolating backward, how long would it be in conventional timescales since we last emerged from such a region? 50kya is a drop in the buck of deep time.

Hmmm, interesting. I think in the past, we made it through relatively OK but perhaps with all the "interstellar crap" we pass through from time to time is part of the ice age cycle. Got any links? I'm really curious now.

In 100 million years, we, or rather the Earth and whomever comes after us, will have been exposed to a great many threats from space. :’)
