An example of trying to explain a phenomenon at a scale well beyond normal human experience:

"If you think of our Sun as a tennis ball in size, the star that formed [supernova 19]87a was about as big as the London Eye. So it's a very massive star.

The pressure and density right in the centre of that star is phenomenal. So it creates this really, really, compact core. A teaspoon of this material, of a neutron star, weighs about as much as Everest. So, it's a very dense, very heavy core that is left behind."
