nah it really doesnt matter does it if your industry suddenly doesnt need you or an injury late into your 20s makes you useless in your field. Spend your 20s learning some, having fun, and learning the life lessons that it takes others the next two decades to learn. Then in your 30s do the same all over again. Life isnt about how far you make it in your job, its everything that happens around it.

i figured they would. So in however many years it takes to develop models, theyd be able to predict trajectories after the collision and see what its new path. Correct? But how far out would they be able to look and would they, or do they, have the projected paths of the entire milky way and all objects in it to predict the natural course of events after collision?

i am absolutely ignorant when it comes to this stuff, but i do remember Ian Malcolm from Jurrassic Park, and I worry what the long reaching dangers of messing with the trajectory of giant rocks in the sky might be. Im assuming they are studying this, but how accurate can they be with regard to where these asteroids would go and what other things might be in their path along the way before hitting it?
