Brian Cox on meaning

Professor Brian Cox on meaning.

"In our galaxy, the Milky Way, there are 4 hundred billion stars and countless trillions of planets.
And yet, it is possible that you can count the number of civilizations on the fingers of one hand.
It's possible that there is only one and that's us... here.
Talk about meaning. There's a word that doesn't sound particularly scientific.
Meaning - what does it mean to exist?
Well I would argue that meaning is a property of intelligence. And if this planet is the only place where intelligence exists, then I would argue that this is the only place were meaning exists in a galaxy of 400 billion stars.
