A cosmic string is a very long (possibly as long as the diameter of the visible universe), very thin (less than the width of a proton) high-density object formed during the early moments of the big bang. You can see a rendering of such a string in the image above. There is a reason why it appears next to the starship Enterprise. Both of them are science fiction.
