The Four Dimensions of Reality

If string theory is correct, we are truly living in this nine or 10 dimensional space. But if string theory is not correct, then we are indeed in this three-dimensional universe. Then, yeah, the four dimensional beings will definitely look at us very differently. I mean, of course, it would be nothing like a three dimensional world. We would go into the fourth dimension and just come like we would just die of like overexposure. Everything.
