The Silurian hypothesis is a thought experiment, [1] which assesses modern science's ability to detect evidence of a prior advanced civilization, perhaps several million years ago. The most probable clues for such a civilization could be carbon , radioactive elements or temperature variation.
The Silurian period was once believed to have enjoyed relatively stable and warm temperatures, in contrast with the extreme glaciations of the Ordovician before it and the extreme heat of the ensuing Devonian; however, it is now known that the global climate underwent many drastic fluctuations throughout the Silurian, [27] [28] evidenced by ...
want to call them. Instead why not embrace a science-based approach: read on as we weigh up the evidence and come to a scientific conclusion about reality. With science you can build a complex explanation for an observation as high as a house of cards or you could invoke Occam’s razor and shave it down to the essential facts.
For example, Newtonian classical mechanics is accurate enough for practical calculations at everyday distances and velocities, and it is still taught in schools. The more complicated relativistic mechanics must be used for long distances and velocities nearing the speed of light , and quantum mechanics for very small distances and objects.
The "mysteries" cited as evidence for the hypothesis can be explained without having to invoke ancient astronauts; proponents look for mysteries where none exist. [9] Since ancient astronauts are unnecessary, Occam's razor should be applied and the hypothesis rejected according to the scientific consensus. [52]

This page lists notable examples of incomplete or incorrect published mathematical proofs. Most of these were accepted as complete or correct for several years but later discovered to contain gaps or errors. There are both examples where a complete proof was later found, or where the alleged result turned out to be false.
