Of course there's a chance--if it's novel, interesting research. Particularly if you can find a research sponser, like someone at a nearby university. (But don't let them take credit for your work, of course.)

I'd exercise a fair amount (perhaps excessive amount) of due diligence to make sure what you're doing is actually interesting, though.

Fundamentally, I don't see why not. You're not saying whether you have someone who mentors you on this project. If not, I would strongly suggest that you try to find a mentor (a university professor working in the field, or at least someone who has published in the field before). In my experience, most professors are very open to working with talented students.

If you're doing this all by yourself, people would be very suspicious that you're being presumptuous about the value of your contribution. So, while in theory, your work should be publishable just based on its merit, in practice, I think the only chance to be published is to have a senior author on paper (this is true even for graduate students)

I am 18 if that makes a difference.
