That is, a 0-brane is a zero-dimensional pointlike particle, a 1-brane is a string, that can either be open or closed, a 2-brane is a "membrane", etc. Every p-brane sweeps out a (p+1)-dimensional world volume as it propagates through spacetime.</b><br /><br />And before you get impressed, I have only the barest understanding of this concept. ;-)Anonymoushttps://www.blogger.com/profile/09452924829161040975noreply@blogger.comtag:blogger.com,1999:blog-12065579.post-59814325343583559442010-02-10T15:36:34.764-05:002010-02-10T15:36:34.764-05:00What are "branes"? ;)What are "branes"? ;)rosebucklenoreply@blogger.com
