Теория Болшого Взрыва под сомнением. Кроме того существует предположение что законы Вселеннои различны в каждом новом цикле и из бесчисленного множества циклов толко настоящии благоприятен для происхождения жизни.
The cyclic universe model
In this context, a new paradigm has been recently proposed by Paul Steinhardt (Princeton) and Neil Turok (Cambridge) -- the cyclic universe -- that turns the conventional picture topsy-turvy.2 (Perhaps the model should be called an old paradigm since it reinvigorates ancient cosmic mythologies and philosophies, albeit using the tools of 21st century physics.) In this picture:
1.space and time exist forever.
2.the big bang is not the beginning of time; rather, it is a bridge to a pre-existing contracting era.
3.the Universe undergoes an endless sequence of cycles in which it contracts in a big crunch and re-emerges in an expanding big bang, with trillions of years of evolution in between.
4.the temperature and density of the universe do not become infinite at any point in the cycle; indeed, they never exceed a finite bound (about a trillion trillion degrees).
5.no inflation has taken place since the big bang; the current homogeneity and flatness were created by events that occurred before the most recent big bang.
6.the seeds for galaxy formation were created by instabilities arising as the Universe was collapsing towards a big crunch, prior to our big bang.
