By the end of Chapter 2 we had made it to 1840 with the discovery of stellar parallax and correspondingly ridiculously large distances to the stars.. At this point, it is useful to introduce a device, similar to the Evil Genius device of Descartes, known as the Random Alien Test (or RAT). Under the RAT device, an alien spontaneously appears and asks random planetary inhabitants basic knowledge questions about the Universe that any "intelligent civilization" would know. So, in 1840 the RAT question would be:. History and Present Status. . Motivated by . the book. :. Breakthrough Beyond the Edge of the World. Valery . Rubakov. Alexei . Starobinsky. Andrei . Linde.

The cosmological argument tries to prove that there is a perfect and well ordered universe, and a world in which we live (cosmos), rather than nothingness, because God brought the cosmos into existence. Theists argue that the universe is perfect because it was created by God and is not the result of random chance (the big bang theory).. Ue. -Li Pen. Tingting. Lu. Olivier Dore. Cosmological Errors.
