A Special Plan With Earth at the Center


A new study led by astrophysicist Erik Zackrisson (Uppsala University), in collaboration with a team of astronomers and astrophysicists from Sweden and the United States, suggests that the planet Earth may hold a very special place in the universe after all. The team’s sophisticated computer model simulated the formation of galaxies, star systems and planets using huge amounts of data from astronomical observations and more recent exoplanet discoveries. Astoundingly, the computer model suggested that there are likely around 700 quintillion (7 followed by 20 zeros) planets in the known universe. Even more incredible is that none of these planets are predicted by the computer model to be like the planet Earth.

This study seems to dramatically contradict not only past estimates of the number of habitable planets in the universe but also commonly held assumptions in astronomy and cosmology. One such assumption is the Copernican Principle, named after 16th-century German-Polish astronomer Nicolaus Copernicus; he made an important contribution to our understanding of the physical universe by explaining that Earth is not at the center of the universe and proposing a heliocentric (sun-centered) model instead. The Copernican Principle is a recent philosophical idea proposing that Earth and Earth-based observers do not hold a unique or even a special place in the universe. The famous late astronomer and cosmologist Carl Sagan, for example, referred to Earth as a “pale blue dot” in his 1994 book of the same name, challenging “the delusion that we have some privileged position in the Universe.”

Many theories in astronomy and cosmology have the Copernican Principle at their core, assuming that Earth-like planets are commonplace in the universe: recent estimates range from 1 billion to 100 billion in our galaxy alone. The SETI (Search for Extraterrestrial Intelligence) Institute and the NASA Kepler Mission focus much of their effort on finding Earth-like planets orbiting other stars.

Whether Zackrisson’s new model of the universe ends up shifting scientific paradigms or simply providing an interesting alternative viewpoint, it certainly gives us pause to consider whether Earth is a unique place and the observers on it are special in the universe.

Even if other planets are discovered that resemble Earth, the Bible indicates that in all the universe there is only one place where a great Creator is working with a very privileged and special part of His creation (Deuteronomy 4:7–8). These observers on the planet Earth have the unique destiny to become sons of God together with all the profound implications that go along with that incredible potential (Romans 8:16–17). Based on what we read in the Scriptures, nothing like this plan and its special purpose for humankind is happening anywhere else in the universe. So, as it pertains to the focus of God’s great plan, Earth and its observers are at the center.
