It seems that the idea of space being made out of some 1 dimensional fundemental entity is popular these days. Not only does string theory propose the structure of space to be 1D loops, but Loop Quantum Gravity proposes a lattice built of similar 1D loops. What is the advantage of this? I know that if you were to shake a string, the vibration would travel down the string at the speed of light, so as to not violate SR and avoid the point particle. But it seems one could apply the same logic to a fundemental loop of 3 dimensions.(adsbygoogle = window.adsbygoogle || []).push({});

So what is the practical benefits of a 1D entity over something of extended dimensions?
