It is literally impossible to overstate how much I love the experiment in this video. It’s so simple and yet shows so magnificently the existence of things almost impossible to believe. It’s beautiful in every way.

The point of the episode the experiment is conducted for is to explain the evolution of life, one of the mechanisms for mutation to be precise. Brilliant in it’s simplicity.

The religious often ask what an atheist has to live for (as if pretending to know something you do not is a reason to live) since we “believe in nothing”. I can honestly say that seeing an experiment like this, understanding what it means, seeing the results – you can freaking see cosmic rays for god’s sake! – is my religious experience. It’s learning things like this, about the world, that is my religious experience. Acquiring knowledge about the world, the universe we exist in, that is my reason to live. It makes me happy.

You could almost say that this phrase errs on the side of being true:

The universe is my god, science is my religion and Carl Sagan is my personal Jesus fucking Christ.

Or Brian Cox as it were.
