I don't really get how strings work.

Anything that is infinitely thin like a string and has mass seems strange, because the smaller the volume of it that you look at, the more dense it appears. The smallest point of it would be so dense its escape speed would exceed the speed of light and it would become a black hole, losing its material properties since black holes only have gravity and rotation. 154.20.194.233 (talk) 06:19, 15 June 2010 (UTC) ...

It is possible on subatomal levels to go faster than speed of light. Mass is the string property which depends of the wave level.
Basecaly, string is a fast moving source (which can even be in more than one place at the same time) which is a source of the wave-particle field. All the properties of the coresponding particle depend on the oscilations on that source string.Čeha (razgovor) 09:01, 6 July 2010 (UTC)

I don´t like the first picture

It puts me off reading. I would remove the picture or change it with another one. —Preceding unsigned comment added by 190.188.3.11 (talk) 01:24, 14 July 2010 (UTC)

What's new ?

Anything new in string theory in the last 10 years? —Preceding unsigned comment added by Alphachapmtl (talkcontribs) 20:31, 5 August 2010 (UTC)

Critical dimension and consistency

The article currently states that the critical dimension of string theory is not fixed by any consistency condition. This is pretty much orthogonal to what I know about string theory. My understanding is that the critical dimension follows from the requirement that the conformal anomaly present in string theory is absent, and that this only happens if there are 26 (or 10 for superstrings) spacetime dimensions. Of course, my info on this may be dated, but my gut feeling is that the work on super-/subcritical string theories is getting WP:UNDUE weight.TimothyRias (talk) 15:35, 6 September 2010 (UTC)
