![]() The prevalent idea was that “there are no stones in the sky, so nothing can come from the sky.” Almost all the meteorites in the France at the time were thrown out in the trash. Great scientists like Newton, Boyle and Lavoisier all rejected the idea of meteorites. Since nothing changed in the sky, there could be nothing coming from the sky, because Aristotle had said so. As late as the 1790’s, the French Academy of Sciences stated all meteorites on the grounds that were simply “thunderstones” produced by lightening hitting the Earth. This view was so prevalent that even until recently, Aristotle’s logic was even used to reject the idea that meteorites existed. ![]() Similarly, the universe as a whole was thought to be unchanging. The planets themselves were thought to be contained inside great crystalline spheres which rotated around the Earth. The area beyond the Moon, the superlunary sphere, which contained the Solar System’s planets and beyond, was considered completely static. Ptolemy speculated, according to Aristotelian principles that the sublunary area, that contains everything below the Moon’s orbit including the Earth, was only governed by the four major elements: Earth, Fire, Water and Metal. In ancient Greek times, the universe was thought to be a completely static entity, guided by Aristotle’s idealistic principles known as natural philosophy. People have been thinking about this question for a long, long time. The idea of the Red Shift has to do with how our universe changes and evolves over time: is it static or dynamic? Does it change or will it always stay the same? To understand this topic better we need to go back a ways in history.
