| Feb 8, 2018 at 4:30 | comment | added | anna v | @BenCrowell One should keep clear in mind that GR is a classical theory, and that elementary particles are quantum mechanical entitities. One cannot use quantum mechanical particles to argue GR points until gravity is really quantized ( unless you want to enter the mathematical terminology of strings where gravity is quantized but not yet modeling measurements, and most people would not be able to follow) . In classical physics there are no particles with zero mass and as far as I can see this answer is within classical physics. | |

Added one word to satisfy a comment.

| Feb 8, 2018 at 0:53 | comment | added | user4552 | for that reason a metric (to use your word, map projection) is used to describe the space, and not differential geometry. This doesn't make sense. A metric is a tool used in differential geometry. | |

Explained a coordinate singularity. Some further clarifications.

Explained the need for quantum mechanics, to correctly answer the question.
