What black holes teach us

I read this in the SMH today:

Physicist John Wheeler, who had a key role in the development of the atom bomb and later gave the space phenomenon black holes their name, has died at 96 ... Wheeler rubbed elbows with colossal figures in science such as Albert Einstein and Danish scientist Niels Bohr, with whom he worked in the 1930s and '40s ... In his 1998 autobiography, Geons, Black Holes & Quantum Foam: A Life in Physics, he wrote that the black hole "teaches us that space can be crumpled like a piece of paper into an infinitesimal dot, that time can be extinguished like a blown-out flame, and that the laws of physics that we regard as 'sacred', as immutable, are anything but".

It's nice to hear a scientist concede such things.
