The whole notion that it was not known that other stars would have planets orbiting them is as absurd as the notion, the Earth is flat. The Universe is geometric, where a pattern exists, that pattern is repeated, that is seen everywhere in the natural world right down to DNA and atomic structure. So now the academic world has informed the population that other planets outside of the solar system do exist and that other life may exist on those planets. What else will they drip feed the masses I wonder.
