Well, what a fascinating documentary (yes another one) I watched last night. It was all about the cosmic threats to our existence. Naturally, they covered the usual stuff about asteroids and comets colliding with the Earth, and made mention of black holes and the death of the Sun. They didnt mention the collision of the Andromeda galaxy with our Milky Way though, but they did cover two rather scary possibilities I'd not come across before. The first was the unlikely but catastrophic if it happened, possibility of the Earth being hit by a gamma ray burst. Supposedly, these bursts occur when a large star collapses into a black hole and it all depends which direction the bursts are pointing in as to whether they hit anything. If one hit the Earth - and we are a very small target all in all, we'd be, well, pretty well done; these bursts are very powerful and nothing would save us from one originating even 1000 light years away. But apparently there are three observable gamma ray bursts a day.... The second was scary and not scary; the "Big Tear". The Big Tear is the conclusion to some physicists work on why the universe is expanding and the final result when it expands to it maximum possible extent. The idea is that dark energy is whats causing the expansion and this wont dissipate but instead lead to more expansion until time and space cant take it any more and gets ripped apart, down to the atomic level. Whilst it would of course, spoil our day a great deal, the ending of time itself would render our day redundant anyway - even if we were to somehow endure, which is impossible since we're made up of atoms that would also be ripped apart. So, all in all we're pretty fucked whatever we do. We can deflect asteroids and comets from our planet. We should by all odds avoid getting hit by a gamma ray burst whilst we're here. We could perhaps one day escape our region of the galaxy and settle on some new planet to avoid the demise of our star. We could perhaps one day even escape our galaxy to avoid the collision with Andromeda. We might just in these escapes, avoid black holes and gamma ray bursts. But if the Big Tear occurs, it will all be for nothing anyway. So why worry? Why worry about anything more than the here and now and enjoying our time as sentient beings? Whether we're good or bad, virtuous or evil, high or low, it has no consequence whatever in the greater scheme of things. We should all do only as much as will profit us and make us happy. E
