Is it safe for my civilization to launch rockets full of hazardous material into the Sun? This question applies to all stars, really, not just the sun.
By hazardous materials, I mainly mean radioactive waste. Just so I don't get answers about how the rockets need special materials and it's not very cost effective, disregard the method of transportation for a moment and focus on the part where the stuff enters the Sun.
Is there any element/polymer/material/anything we have today that could harm the Sun if we dumped it into it? Although I'm doubtful that there would be negative effects, would dumping large amounts reduce the life of the Sun? (I'm mainly concerned if it changes the life by at least a few thousand years.) If you know how long it would reduce the life, go ahead and put it in the answer, as I'm sure someone will find it helpful.
