Edit: Thanks Eric for the link that addressed my questions/concerns.

Imo, rail guns and gravity couches are far more feasible and that technology does exist today. I hope we develop something before the Kessler syndrome (when space junk in orbit is so prevalent it's impossible to avoid and constantly increasing, like in "Gravity") makes orbiting or leaving earth impossible. That day is approaching quickly.

Of the many ways one might die I think death by hypoxia as you tumble into the black aint so bad. Your body would probably get a pretty nice cremation when your orbit takes you back towards earth.

ps. Kessler Syndrome is a bitch.
