Critique of Stephen Hawking’s “Grand Design”

An excerpt of Hawking’s latest theory showing it is not new at all:

Actually M-theory is just the latest iteration of string theory, with membranes (hence the M) substituted for strings. For more than two decades string theory has been the most popular candidate for the unified theory that Hawking envisioned 30 years ago. Yet this popularity stems not from the theory’s actual merits but rather from the lack of decent alternatives and the stubborn refusal of enthusiasts to abandon their faith.

M-theory suffers from the same flaws that string theories did. First is the problem of empirical accessibility. Membranes, like strings, are supposedly very, very tiny—as small compared with a proton as a proton is compared with the solar system. This is the so-called Planck scale, 10^–33 centimeters. Gaining the kind of experimental confirmation of membranes or strings that we have for, say, quarks would require a particle accelerator 1,000 light-years around, scaling up from our current technology. Our entire solar system is only one light-day around, and the Large Hadron Collider, the world’s most powerful accelerator, is 27 kilometers in circumference.
