2. Such problems include the horizon problem and the flatness problem.
3. The principle can be applied to solve the flatness problem in two somewhat different ways.
4. For these reasons work is still being done on alternative solutions to the flatness problem.
5. Maybe we have articles on the flatness problem and on cosmic inflation which explain more.
6. It's difficult to find flatness problem in a sentence. 用flatness problem造句挺难的
7. Despite this ongoing work, inflation remains by far the dominant explanation for the flatness problem.
8. This success in solving the flatness problem is considered one of the major motivations for inflationary theory.
9. Guth discussed this with Linde, who had independently been working on bubble inflation, but without considering the flatness problem.
10. Some cosmologists agreed with Dicke that the flatness problem was a serious one, in need of a fundamental reason for the closeness of the density to criticality.
11. In August, he submitted his paper, entitled " Inflationary universe : A possible solution to the horizon and flatness problems " to the journal " Physical Review ".
12. The "'flatness problem "'( also known as the "'oldness problem "') is a cosmological fine-tuning problem within the Big Bang model of the universe.
13. An example of a fine-tuning problem considered by the scientific community to have a plausible " natural " solution is the cosmological flatness problem, which is solved if inflationary theory is correct : inflation forces the universe to become very flat, answering the question of why the universe is today observed to be flat to such a high degree.
14. The problem was first mentioned by Robert Dicke in 1969 . The most commonly accepted solution among cosmologists is cosmic inflation, the idea that the universe went through a brief period of extremely rapid expansion in the first fraction of a second after the Big Bang; along with the monopole problem and the horizon problem, the flatness problem is one of the three primary motivations for inflationary theory.
15. For example, in 1979 Bernard Carr and Martin Rees argued that the principle  is entirely post hoc : it has not yet been used to predict any feature of the Universe .  Others have taken objection to its philosophical basis, with Ernan McMullin writing in 1994 that " the weak Anthropic principle is trivial . . . and the strong Anthropic principle is indefensible . " Since many physicists and philosophers of science do not consider the principle to be compatible with the scientific method, another explanation for the flatness problem was needed.
