There is no way a Universe without life could be observed – The Anthropic Principle
The Anthropic Principle is an odd idea I would like to see proven – recent evidence shows that were the universe just slightly different, it wouldn’t exist long enough for any life to develop. The odds of a universe that we can exist in are very small, based on chance. – but there is no way a universe without life could be observed.
It is true that our particular form of life would have been impossible without “fine tuning” of the universe’s structure, but we do not know if there could have been equally fine-tuned, yet fantastically different universes supporting biological life. Anthropic principles fail to explain why our universe is in one such fine-tuned state, when “all things being equal”, it was much more likely to develop into chaos.
People use the anthropic principle to argue that the Universe must be exactly as it is because we exist the way we do. And that’s not only untrue, it’s not even what the anthropic principle says.
“Although our situation is not necessarily central, it is inevitably privileged to some extent.”
