Black Holes and Revelations

A black hole is a region of spacetime centred on a point mass called a singularity. A black hole is extremely massive and thus has an immense gravitational pull, which is in fact strong enough to prevent light escaping from it.

"Science is a match..."

"Science is a match that man has just got alight. He thought he was in a room - in moments of devotion, a temple - and that his light would be reflected from and display the walls inscribed with wonderful secrets and pillars carved with philosophical systems wrought into harmony. It is a curious sensation, now that the preliminary splutter is over and the flame burns up clear, to see his hands lit and just a glimpse of himself and the patch he stands on visible, and around him, in place of all that human comfort and beauty he anticipated - darkness still."

H.G. Wells, "The Rediscovery of The Unique"

Ah!

Football Fields

Here's a thought: I'm always seeing videos or articles that try and give you a sense of how big (or small) things are. For example, if a hydrogen atom was the size of a football field, the nucleus would the size of a grain of salt.
That's all well and good (except it's pointless to try and comprehend that sort of scale. But that's for another post).
The thing is, comparisons using the size of a football field are really common in these things. Pretty much everything is measured relative to a football field when a science is thrown at the public. My - perhaps trivial - question is: what kind of football field? They use the same comparisons in the USA and the UK, only here we mean football fields, and in America they mean American football fields.
It's not important, it's just something to think about.
