Hi! Today I was reading this article in SciAm on a model that some string theorists were working on that had to do with the cosmic origin; it talked about how strings, when compressed - when losing energy - will only decrease in length to the Planck length, and its energy level would rebound as its length actually increases as one attempts to compress it or drain its energy further. I'm just wondering that, when the temperature of a string - theoretically - is lowered, approaching absolute-zero, wouldn't it reach the Planch length some temperature above absolute-zero? And if you still lower its temperature - assuming that it's not absolute-zero yet - wouldn't it actually increase in size, and not decrease in size to nothingness at absolute-zero - theoretically? Please tell me that I made a mistake in this reasoning or I misunderstood something; it's quite disturbing for me. If an answer is out there, great! Please tell me. Thank you very much!
