It took about 100 years for the idea of the sun being the center of the solar system instead of the Earth to become popular after Galileo’s telescope showed moons going around Jupiter in 1610. The math was simpler if the Earth moved around the sun, but in spite of many experiments, there is no scientific proof whether the Earth moves or not. As Einstein put it, “…nor has any physical experiment ever proved that the Earth actually is in motion. ”[1] [emphasis added] “Either coordinate system could be used with equal justification. The two sentences: ‘the sun is at rest and the Earth moves,’ or ‘the sun moves and the Earth is at rest,’ would simply mean two different conventions concerning two different coordinate systems.”[2] Physicist I. Bernard Cohen wrote in 1960: There is no planetary observation by which we on Earth can prove that the Earth is moving in an orbit around the sun. Thus all Galileo’s discoveries with the telescope can be accommodated to the system invented by Tycho Brahe just before Galileo began his observations of the heavens. In this Tychonic system, the planets…move in orbits around the sun, while the sun moves in an orbit around the Earth in a year. Furthermore, the daily rotation of the heavens is communicated to the sun and planets, so that the Earth itself neither rotates nor revolves in an orbit.[3] The NASA physicists with whom I worked always put the center of an orbit wherever was most convenient: “We know that the difference between a heliocentric (sun-centered) theory and a geocentric (earth-centered) theory is one of relative motion only , and that such a difference has no physical significance. ”[4] [emphasis added] This book shows that none of the giants of astronomy, not Galileo, not Sir Isaac Newton, not Einstein, was convinced that their mathematical formulas that agreed with data about planetary motion as observed from Earth necessarily meant that the Earth was just one insignificant bit of dust among billions. Modern scientists don't want to admit that the Earth is the center of the universe. They know that if the Earth is the center, God put it there, and should get with His program. This book explains the absurd logic cosmologists use to try to explain away the many experiments that put the Earth at the center. Since even Einstein agrees that we can put the center anywhere we like from a mathematical point of view, there is no conflict between science and Scripture. Christians should have no trouble believing God's Word that plainly teaches that the Earth is the unmoving center of the universe.
