  • First - The major problem with trash isn’t the getting rid of it part, it’s the gathering it up part. If we could do that, it wouldn’t be a problem.

    Second - Launching things on a rocket is kinda dangerous still, there’s a risk the rocket will blow up on launch, scattering the material across a large area. This is a big reason why things like nuclear waste is a problem to transport in general, much less flying it somewhere.

    Third - Launching something into the SUN is really hard, it would be easier to send something out of the solar system than back into the sun.

    Fourth - Someday we’ll figure out a use for everything, wall-e style. If we dump everything into a centralized landfill, we’ll eventually be able to collect/sort/recycle it into something useful. Throwing it into the sun (or off-planet) would make that stuff unavailable forever.

    Finally - Throwing stuff into the sun would actually get rid of it forever, yes. It would be completely decomposed into the atoms it was made from. If we threw ENOUGH heavy metals into the sun, we could actually poison the sun making it not able to fuse hydrogen anymore, but even if we threw the entire earth into the sun, it wouldn’t be enough.

    That’s one of the ways proposed for terraforming Venus. Put in a sun shield to freeze the planet, let the CO2 snow down, then process the CO2 into something that can sequester it away so it doesn’t just go back into the atmosphere after removing the sun shield.

    Of course none of that is technically possible right now, but it’s a lot easier on a planet that has no (known) life to destroy while working through the process.

    New math came out of it, they figured out more and more efficient ways to figure out the solution to “is this prime?”

    Those same math techniques can be used for other problems, and possibly learn something that solves a problem you actually care about.

    Research is important because you never know what weird problem someone is working on might solve. Maybe it will provide a new math solution that creates better CGI, maybe it’ll finally create a technique to solve fusion.

    Maybe it’ll just be something that we know now that we didn’t know before. There are FAR FAR FAR more wasteful things in the world than some nerds trying to solve big prime numbers.
