… not only are we fortunate to live in the safe zone or sweet spot in our solar system, but our solar system is in the safe or sweet zone of our galaxy … our galaxy is about 100,000 light years in diameter and there is a sweet spot that is roughly 15,000 light years across between the outer edges of the galaxy and the inner part of the galaxy … a space of relative calm at least for the present where star systems like ours can form and not be stripped of planets or the star (our sun) be shredded by the massive stars further in. How long would it take to cross the Milky Way in a space ship going say 18,000 mph? about 4 billion years or about the time our little solar system has left … traveling by commercial jet at typical speeds about 120 billion years … give or take a few … and we know that the light from the outermost galaxies from us has been traveling for over ten billion years to get here. We sure will be able to save everything … huge smiles.
