re: Constants of physics,
The universe is such that life could appear and thrive.
It's not at all the same as saying the universe was designed for life.
Is it luck if life appeared? A universe with different constants could be a lot more interesting than a universe where life exists.
It all depends on the point of view.
The problem with us, living creatures, is that we are born, we grow, we multiply and we die when the Sun only travels 1/2.800.000th of the time it takes to turn around the galaxy!
I don't think we're that lucky!
