"I think it is one of the most interesting things to happen in quantum gravity for quite some time"
Renate Loll of Utrecht University, the Netherlands
A paper recently published on Arxiv suggests that, due to the effects of quantum gravity, on tiny scales, 3D space may give way to mere lines.
The New Scientist reports that researchers working on theories of quantum gravity, which aim to unite quantum mechanics with general relativity, have recently noticed that several different quantum gravity theories all predict the same strange behaviour at small scales: fields and particles start to behave as if space is one-dimensional.
"There are some strange coincidences here that might be pointing toward something important," says Steven Carlip at the University of California, Davis.
So on a quantum level, space is dot & lines created from vibrating strings ...
