(If they were moving towards us, they’d appear more bluish!) It’s so stretched out it’s color changes. And the faster they’re moving the redder they appear, as the wavelength of light is stretched out. Distant galaxies are flying away from us. ![]() Edwin Hubble showed that it’s expanding, at an increasing rate. Then in the early Twentieth Century, new discoveries showed that indeed that universe is definitely not static. He used a telescope to the see the moons that orbit Jupiter, even though he originally thought them to be part of another solar system. However, in the Seventeenth century, Galileo confirmed the Copernican Heliocentric idea. Earlier, Copernicus had resurrected the Heliocentric theory, originally proposed by Aristarchus, and rejected by philosophers at the time. The idea of a changing universe did indeed start much earlier than the French meteorite experience. ![]() The French Ministry of the Interior commissioned a study and decided that meteorites did indeed exist after all. However, in the end, facts won out over philosophy when over 3,000 meteorites fell during the daytime in the town of L’Aigle, France on April 26th, 1804. 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.
