Just the other day we received the Noble Prize in Physics in Canberra for discovering that time and space are not only expanding but also accelerating.
This is an extraordinary discovery and quite unexpected. No one expected that time and space were accelerating.
So we wonder what happens when accelerating time and space are compressed in the centre of Black Hole.
What we would have is an immovable object, the three dimensions of space and time accelerating out, meeting an immovable object, the gravitation at the heart of a Black Hole, accelerating in.
Accelerating time and space and accelerating gravity would have nowhere to go, so instead of going nowhere, they start producing new dimensions at an accelerating rate. So the centre of a Black Hole remains at the planck size but starts producing new dimensions at an accelerating rate.
This has the interesting effect of connecting everything to everything else, and so cause and effect come to an end.
In the Steam Age the steam train was our metaphor of choice, and in the Age of the Internet where everyone is connected to everyone else, the internet is our metaphor of choice, even for the singular heart of a Black Hole.
