I’m sure there’s a perfectly good reason why we haven’t done this yet. Too expensive? Would launching it into the sun cause the smoke (if there is even smoke in space) to find its way back to Earth, therefore polluting the air?

This is an incredibly stupid question.

    Just to add to this: rockets use a lot of fuel. And with “a lot” I mean that a rocket typically is 90% fuel, 7% rocket, 3% cargo (my numbers may be off a bit, but not by much). The further you want to go the more fuel you need, the heavier you get,the more fuel you need, and so on.

    So to move out 100 tonnes of cargo, were going to waste, say 3000 tonnes of fuel, and that is just to get it into orbit. Getting enough speed to get it to the sun would probably literally require exponential amounts of extra fuel, which would require extra fuel rockets to come up, rockets just carrying “a little bit of” fuel for another rocket.

    Then on going to the sun: the earth moves at about 30km/s around the sun. To cancel that out, you’d need a rocket capable of reaching 30km/s, which we currently -afaik- cannot. We can’t get rocket engines that can eject the burning gasses out at those soeeds, hence we can’t reach that speed, hence we can’t cancel out 30km/s. We’d need entirely new technology to be able to do that
