If a point particle is a string viewed end on in three dimensions, or is a zero brane, isn't this merely a perspective? Are open strings really more like ribbons given the dimension of time and are closed strings more like tubes seen end on? If so, could this mean that the string's length is actually determined by temporal properties in four dimensions as a point particle is a line if the dimension of time is included? I've read that strings can't be any smaller than the Planck length but that some may have expanded during the inflationary period to become 'cosmic strings'. But surely these same factors would apply whatever the size of the string because of the temporal aspect?
Does particle decay really mean that strings lose energy over time because of quantum effects? The vibrational energy of a string must surely be confined within the string in order to maintain its energy state so isn't any possible energy loss due to something similar to Hawking radiation? If a string made of energy 'vibrates' with energy doesn't the vibrational energy of a string consist of a different type of energy from the string's constituence? Are these oscillations 'bouncing' from one end of the string to the other, and are these confined merely to the 'end' of the string that we perceive from our dimensional perspective or could they go beyond, i.e. from past to future and vice versa if time is included as length?
