If you are serious about MIT, you may want to focus on studies first. By study, I mean your regular school and classes and stop worrying about second dimension of time. It may be there or not there, who cares, and even if you can prove or disprove it - you need to show that that you can solve high school level problems first. Learn physics, participate in olympiads and get to top 400 in country . It is quite hard even solving basic mechanics problems first. (Search for F=MA exam and USAPHO and see the problems there).
Even whole of string theory is giant question mark. It may be true, or may not be true. We will find out possibly in this century, and you just might be the person who get it right, eventually. But basics first. Solve toy problems of physics first, before getting into PhD level stuff.
I don’t know what part of country you are located in. If you within few hundred miles of MIT, check out high school programs that MIT offers. There are literally hundreds of programs, mostly free, that MIT provides to high school students. Check out MIT Office of Outreach. Check out MIT Inspire,. MIT Junction, MIT PRIMES, MIT RSI , MIT Beaverworks, MIT Broad Institute Summer Scholar, MIT Think and so on. No other university in the world is as welcoming to high school students as MIT. They nurture the talent early on and for free.
In general, if you are doing research without a mentor, that’s a red herring. Why? Because you don’t know if you are on right path or not. Plenty of high school students have published research (some from MIT programs), but they worked with someone more knowledgeable than them.
