Could Someone explain "M" Theory to me?

Answer 1

When Witten named M-theory, he did not specify what the "M" stood for, presumably because he did not feel he had the right to name a theory which he had not been able to fully describe. According to Witten himself, "'M' stands for 'magic,' 'mystery' or 'membrane,' depending on your taste." Also suggested, has been 'matrix' (see below) and 'mother of all theories'. Cynics have noted that the M might be an upside down "W", standing for Witten. Others have suggested that for now, the "M" in M-theory should stand for Missing or Murky [citation needed]. The various speculations as to what "M" in "M-theory" stand for are explored in the PBS documentary based on Brian Greene's book "The Elegant Universe."
The name M-theory is slightly ambiguous. It can be used to refer to both the particular eleven-dimensional theory which Witten first proposed, or it can be used to refer to a kind of theory which looks in various limits like the various string theories. Ashoke Sen has suggested that more general theory could go by the name U-theory, which might stand for Ur, Uber, Ultimate, Underlying, or perhaps Unified. (It might also stand for U-duality, which is both a reference to Sen's own work and a kind of particle physics pun.)

Answer 2

In physics, M-theory (sometimes also called U-theory) is put forward as the master theory that unites the five superstring theories. Edward Witten of the Institute for Advanced Study proposed the existence of this physical model at a conference at USC in 1995, explaining a number of previously observed dualities and sparking a flurry of new research in string theory, called the second superstring revolution. The article below describes M-theory in detail. It's a long article but I think reading the artile is worth the time.

Answer 3

No. Someone may be able to explain what it is supposed to be, or the purpose of it, but they aren't going to be able to explain it to you. Nobody can, because there IS no complete M-theory, yet. We don't even have a consistent answer for what the M stands for, anyway. I say it stands for membrane, but someone else would say master. Or mystery, or magic, or math, or main, or "My God, this is a horribly convoluted theory", depending on who you ask, the phases of the moon, or whatever else you please.

Answer 4

One of the easiest to understand explanations I have read.

"M" was the boss of agent 007.
