Earth - Optimized for observers
"The most incomprehensible thing about the universe is that it is comprehensible." Albert Einstein.
The same narrow circumstances that allow us to exist also provide us with the best overall setting for making scientific discoveries[63] .
Within the sun's family of more than 70 planets and moons, earth is one of 7 bodies enveloped by a canopy of gas, yet only among these 7, can earth maintain complex life and only the earth's atmosphere is transparent.[63]
"Earth is bombarded from space from our sun and distant galleries by the electromagnetic spectrum: gamma, x-rays, ultraviolet, visible, infrared, microwave, radio. [Visible light,] the sliver of radiation that is essential to plants, animals and human beings is the part of the spectrum that provides us the most information about the structure of the universe." Jay Richards, Philosopher, Discovery Institute[63]
"This sliver is one trillionth of a trillionth of the universe's range of natural electromagnetic radiation. It's something that you wouldn't expect chance to produce. Why would the universe be such that those places that are most habitable also offer the best opportunity for scientific discovery? I believe this implies purpose." Guillermo Gonzalez, Astrobiologist, Iowa State University[63]
From naturalistic assumptions, we would not expect the universe to be understandable by human reason. - Robin Collins, Philosopher of science, Messiah College.[63]
"You put observers in the best place for observing, that is if you're going to do things intelligently, that's what you'd do. The nature of our planet, the nature of its atmosphere, the location in the solar system, the type of solar system, even the type of star and the location within the galaxy are optimal for making a wide range of scientific discoveries. It turns out that those are also all the most important conditions for a habitable planet - that is a planet that is conducive to beings like us and without which we could not survive. I think that's just the sort of pattern to suggest to people conspiracy than mere coincidence." Jay Richards, Philosopher, Discovery Institute[63]
