... We live for a while in some state which is called ... there is no — Andrei Linde

"The theory of the inflationary multiverse changes the way we think about our place in the world. According to its most popular version, our world may consist of infinitely many exponentially large parts, exhibiting different sets of low-energy laws of physics. Since these parts are extremely large, the interior of each of them behaves as if it were a separate universe, practically unaffected by the rest of the world. This picture, combined with the theory of eternal inflation and anthropic considerations, may help to solve many difficult problems of modern physics, including the cosmological constant problem."

"Many scientists are still ashamed of using the . Just as the friends of were afraid of using the name , the opponents of the anthropic principle often say that they do not want to use the A in their research."

"The best available explanation of the observed uniformity of the universe is provided by inflation. However, as soon as this mechanism was proposed, it was realized that inflation, while explaining why our part of the world is so uniform, does not predict that this uniformity must extend to the whole universe ..."

"Why is our universe so homogeneous? Why is it not exactly homogeneous? Why is it isotropic (same in all directions)? Why all of its parts started expanding simultaneously? Why is if flat (Ω = 1)? Why is it so large? Answered by inflation"
