Life and the universe compare to each other like a child and a parent, parent and offspring.

The question we ask is - if there is life on other planets, should we expect it to be based on the same molecules, i.e. be universal - or should we expect it to depend on the local conditions, i.e. on the planet's geochemistry. So to find out, we try experiments on biomolecules, starting with such geochemistry conditions.

There is immense, powerful potential in life in this universe - especially now that we know that places like the Earth are common. And that potential, that powerful potential, is also our potential, of you and me.
