In the book the Grand Design by Stephen Hawking, he wrote about the M-theory, and how in that theory it has 11 dimensions. I do not quite get that, so can someone explain it to me a little bit. I understand four dimension is where space and time combine together, and there is no movement in four dimensional space because an event over time is represented by a line. I get that, but I do not quite understand how 11 dimension works, so I would really appreciate if anyone could help me understand this concept.
