GR and my journey to the centre of the Earth?

Question

>> [General Relativity] basically says that the reason you are sticking to the floor right now is that the shortest distance between today and tomorrow is through the center of the Earth. > > I love this, not the least because it sounds nonsensical. (From an [unassessed comment in the internet](http://arstechnica.co.uk/science/2016/04/the-search-for-hidden-dimensions-comes-up-empty-again/?comments=1&post=31030951#comment-31030951)) OK so I love this too, but is it a completely looney description or does it make any sense in which case I'm in for some serious enlightenment today since last time I checked light cones allowed me to move somewhat freely unless in significant proximity with a singularity.

Answer 1

Einstein's tensor equation (solve for connection coefficients)
