INSIGNIFICANT...Some feel that modern science has diminished the role of humanity in the big scheme of things. I think it's quite the contrary. Judged in terms of information theory, a single human being is more significant than an entire galaxy.
A supercomputer can create a convincing simulation of the motion and evolution of 20 million galaxies simultaneously. We don't yet have a convincing simulation of a human being on a supercomputer, and we probably won't have one any time soon.
Human beings, and living organisms in general, are information-dense assemblies of matter. We're the polar opposite of black holes. Unlike black holes, we do have hair.
