  1. The anthropic principle is very simple.

    The world, as physicists know it, is based on several laws and physical constants – such as Planck's constant, the speed of light, Avogadro's number, the gravitational constant, etc.

    For example, Planck's constant is 6.626 070 15 10 10-34 kg * m2·s-1 (J·s)

    But what would happen if at least one of these numbers changed? The universe would still be there, even if it was arranged differently, but man would not and could not exist. How did it turn out that all these numbers in all constants so successfully coincided? It is unknown, but the anthropic principle is an idea that draws our attention to this randomness/non-randomness.

  2. The anthropic principle is an attempt to explain why the fundamental parameters of our universe are so well aligned that they allow intelligent life to appear. It exists in two versions:

    1. Weak anthropic principle: this is a typical survivor's systematic error. There can be any number of different universes with different parameters, but only in those Universes whose parameters allow the existence of intelligent life can a being appear who asks the question ” Why are the parameters so well formed in my Universe?”
    2. Strong anthropic principle: there can only exist universes whose laws allow for the existence of intelligent life. In this version, the anthropic principle means either that the universe has a pre-defined goal, or that there are some yet undiscovered laws of nature that choose among all possible universes exactly those that then generate intelligence.

  3. Extremely simplified:

    1.Weak anthropic principle: We observe that region of the universe whose structure and properties are suitable for the origin and development of intelligent life.

    2.Strong anthropic principle: The universe must have the properties that allow intelligent life to develop.
