Why Don't We Shoot Garbage Into The Sun?

It's funny how this question keeps coming up every few years. I remember my father giving me the short and dirty answer 25 years ago...."you know how much that would cost?"

But even then, the Sun is 93 million miles away, and you’d still need an enormous amount of (expensive) fuel to get the rocket to plummet into the Sun if you took the direct route. Pontzen reckons that, unless you plan the mission very carefully, you’d need about 10 times more energy for the trip between Earth and the Sun’s surface than you’d already spent getting into orbit.
