One of the more interesting things about scientific advance is to suppose that evolution on Earth is an expression on how the universe works. If evolution is something that can be charted across all the galaxies, within the galaxies themselves, then when we find something that works, some way in which matter acts and reacts, we are not just discovering a new thing but something important about answering the question, Why should this exist? Its a little like knowing that blood flows to take nutrients around the body without know anything about nutrients but finding out blood flows.
So questions such as Why is there electricity?, become even more interesting than the things you can do with it on Earth. Because it involves us in wondering why there is energy, not simply that it is useful for for us. In fact it will eventually answer the question we all want to answered, Why are there human beings? Because the answer will not be just to do with this planet, but the whole universe. Just like a body evolving so that its constituent parts all progress the whole, so the universe works the same way, and i suggest that because the Earth mirrors the physics of the universe itself.
I don’t have any answers, unless it is that human beings have the potential to save all life that evolves everywhere and transport it at times when planets die to new planets. On a universal scale though that doesn’t seem very important.
Maybe we aren’t.
