An anthropic principle is any of several similar explanations for the nature of the universe, which state that either the universe is as it is because otherwise we wouldn't be able to observe it, or that the presence of intelligent life constrains the universe to its current form.

The anthropic principle is the idea that the universe must be compatible with the existence of conscious life because if it were not, we would not be here to observe it. It suggests that the fundamental constants and conditions of the universe are finely tuned to allow for life as we know it. There are different versions of the anthropic principle, ranging from the weak form, which states that the universe must be suitable for life because we exist, to the strong form, which posits that the universe was specifically designed for the emergence of intelligent life.

Who discovered the anthropic?

anthropic principleThe anthropic principle is the philosophical argument apparently first stated by Brandon Carter, and popularized by Nick Bostrom.There are a variety of forms -- the weak anthropic principle, the strong anthropic principle, the final anthropic principle, etc.It may have implications for fundamental physics and cosmology.anthropic robotMany people have developed anthropic robots, also called androids.While artificial devices in more or less the shape of humans have stirred the imagination for centuries, perhaps the first bipedal walking robot was the 1995 Wabian from Waseda University.

How is the anthropic principle a challenge to naturalism?


How do you make a sentence using the word anthropic?

The anthropic principle suggests that the universe is finely tuned for the existence of human life.

The lesser anthropic principle. Expanding on that a bit: if the Sun were NOT a main sequence star, we wouldn't be around to be asking the question.

How does the anthropic principle challenge evolution?

The anthropic principle does not challenge evolution; instead, it attempts to explain why the universe and its physical laws are suitable for the development and sustenance of life. Evolution, on the other hand, is a scientific theory that explains how life diversifies and adapts over time through natural selection and genetic variation.

What is an anthropic coincidence?

An anthropic coincidence is a coincidence in the known physical constraints within this world, the result of which means that life without it would be impossible.

Why is everyone human?

By the anthropic principle, they are human because they are. That is to say, if you were something else then you would not be human but would instead be...what you would be, and from that position could still ask "why am I what I am?". Or alternatively, you could answer that humans are what they are because nature ran the way it did, which leads back to the anthropic principle anyway.

Will other galaxies ever be fit for life?

Yes. According to the Anthropic principle, Life is an essential part of the Universe and it was not an accident. "The Universe knew that we were coming..." or so I read once. If the constants of Phyics are exactly tuned to support life, then what would make our planet so special? Nothing. The Universe is full with life forms.

There was this 1970s principle that if scientific constants were fractionally off universe would be very different and was used to prove God exists who came up with it?

This is known as the Anthropic Principle. In 1961 Robert Dicke noted that the age of the universe as seen by us cannot be random. Rather, biological factors constrain the universe to be more or less in a "golden age," - neither too young nor too old. If the universe were one tenth as old as its present age, there would not have been sufficient time to build up enough heavier elements by stellar nuclear fusion. If the universe were 10 times older than it actually is, most stars would have turned into white dwarfs, and stable planetary systems would have already come to an end. Thus Dicke explained that there was a huge coincidence between large numbers constructed from the constants of physics and the age of the universe. This idea then spread so that by the 1980s many universal constants were realised to be not the result of simple coincidence or random, but seemed to be of values that enabled life to exist. Any tiny fluctuations outside these values would render the universe incapable of sustaining life. This Anthropic Principle became a tool in suggesting that Creation was not a random occurrence but that there was evidence of design in the universe. We are a long way from the Anthropic Principle 'proving' that there is a God, as the questioner suggests, but it does point in the direction of firm evidence that there is design as opposed to just chance in the observable universe.
