The strong version of the anthropic principle in essence states that the observed values of physical and cosmological quantities are not accidents but are connected somehow with our existence as observers of the universe. The universe was built for us. This sounds like an extraordinary statement, yet at the level of microscopic physics there is a clear tradition in quantum mechanics of a relationship between the observer and the thing being observed. Our best microscopic theories of nature state that it is impossible to observe physical systems without disturbing them. In other words, the observer and the universe are entwined and intimately connected at the level of microscopic physics. How this might play out on larger scales is utterly unclear, but it is not true that the universe in every essence exists independent of our observation.
