More accurately, trillions of stars

There is a place in the universe, about 94 thousand, six hundred and eight million million kilometres away, where two clusters of galaxies are colliding at millions of miles per hour. Well, more accurately, this all happened a hundred million years ago, it's just that we've only just learnt of it.

The explosion caused by this unimaginable collision has certain properties that seive the dark matter from the rest. In case you don't know, dark matter is a substance that has gravity but no other properties: it is invisible, untouchable, and is everywhere. Generally, speaking, this is a hard thing to measure. High fives all round, humanity, because we've done it.

There are those, of course, who don't have any truck with something of unimaginable scale that couldn't be seen until we had vast telescopes at various points around the globe. They're the ones who maintain that there are lights in the firmament of the heaven to divide the day from the night; and to be for signs, and for seasons, and for days, and years. For people, in other words. Interestingly, someone who themselves believed this once accused me of 'worshipping' mankind, as opposed to the worldview they were selling as a more enlightened, cosmic way of seeing.
