What ACTUALLY happens if you travel back in time

Physics doesn't actually forbid travelling back in time. So what if someone built the machine? You'd probably land in outer space. You'd have to deal with the grandfather paradox, the bootstrap paradox and Stephen Hawking's "Chronology Protection Agency". And if the machine broke and left you stuck in the year 1300, could you survive? The language, the money, the law, the food, the medicine, and what's coming in 1315 and 1348.
