M-theory The problem with
superstring theory is that, quite simply, there are too many superstring
theories (at least five), each of them perfectly valid. Edward Witten noted that a few of them were simply the same theory viewed from
different angles, and proposed the M-theory, the theory of all possible
superstring theories ("Heterotic and type I string dynamics from eleven
dimensions", 1995). It turns out that M-theory can also be viewed as an
eleven-dimensional theory of ten-dimensional theories. M-theory does
not constrain the universe to be the one we observe: a staggering 1 to the 500th
power different kinds of universe are technically possible, each with its own
laws of nature. The US physicist Leonard Susskind has suggested that all those universes might indeed exist:
anything that can exist, does exist. Our universe is merely one item in the
"megaverse." Back to the beginning of the chapter "The New Physics" | Back to the index of all chapters |
