General Relativity On Black Holes — Through Systemic Functional Linguistics

Hawking (2005: 49):
Penrose and I showed that general relativity predicted that time would come to an end inside a black hole, both for the star and for any unfortunate astronaut who happened to fall into it.

From the perspective of Systemic Functional linguistic Theory, the notion of time coming to an end corresponds to the relative expansion of time intervals to ∞ at the singularity of a black hole, where space intervals are relatively contracted to 0.

(Interestingly, both singularities (general relativity) and travelling at the speed of light (special relativity) have exactly the same effect on time and space intervals.)

But between the singularity and the event horizon, time intervals are less than ∞, so time has not quite come to an end, and space intervals are more than 0, suggesting that any matter–energy there is crushed into that space.
