Thank you for this page.
I am sick of hearing about how there are an infinite number of worlds so there is one just like this one....
Infinity is an old human concept, usefully employed in mathematics as 'shorthand' for very huge. But it isn't a 'thing' - it can never 'be' (because you never get there).
If the mass at the centre of a Black Hole was infinite why don't they just swallow up the whole universe like a huge reverse-big-bang vacuum cleaner, why have a horizon at all if you're 'infinite'?
The nonsense theories appear to be due to the paradoxes caused by trying to take this 'concept' literally.
