A group for those interested in science from the vast expanse of the universe or technology.
I've been mystified recently about the nature of "significance". Is something significant because it's big, so the galactic scale is the most significant? Or because there's lots of them, so the subatomic level is the most significant? Or maybe it's complexity, so the workings of the brain are especially significant?
I love this quote, it puts things in scale- however, why precisely is something important? What is significance?
It depends on scale. At our scale, an Ant is insignificant. This is no so at an Ant's scale or point of view. Then again, we are insignificant compared to the planet we live on. Well, used to be, not anymore because we are having a global impact. So I think "significance" really has to do with the impact we make.
But the impact of a galaxy and the impact of an ant are ultimately more or less the same once we reach the end of the current universe, so over a scale of time (which opens another possibility: is the time something lasts what makes it significant?) they both cease to have any significance impact-wise.
Still think that the Universe was built for you xP ?
Something I'm really curious about is life in other planets, do the same laws of variation and natural selection apply to them? Do they look like humans or any other animal here on Earth? Do they breathe oxygen as we do? Are they anatomicly similar or the same as us?
