WebJun 1, 2024 · The idea that the universe started with a Big Bang is a key tenet of the standard model of cosmology. But that model is a lot less scientific than it’s taken to be. To begin with, we can never have direct evidence of the Big Bang itself, and so if we are to accept it, it must be as a metaphysical, not a scientific hypothesis. Furthermore, the … WebThe gravity model estimates the pattern of international trade.
