Very interesting discussion relating to spacetime geometry and the speed of light.

The discussion started on reddit and split to Hacker News.

Yes, excellent! Got to say I'm surprised to find something so good on those web sites. Thanks for finding this.

Great! The original poster was right, i like that idea of thinking about it a lot more, it is in a way more beautiful. Also correct me if I'm wrong, but does that mean that Light in a vacuum doesn't move forwards in time?

Jordan, I am not sure (hence my desire to come to uni) but I think we can say that since a photon is massless and is travelling through space at "c" then from its perspective there is no such thing as time.

Right.
