Models of universe | Earth, Solar System and Universe.
Traditionally, the cosmology imagine the universe as a linear model. I.e., a single universe with a beginning and, probably, an end. For the linear model, the Big Bang is the beginning of everything: space, time, physical laws and all matter and energy. There is a single universe and all that encompasses exite. But the linear model has contradictions and does not resolve all the issues. For this reason, other models were raised.
Einstein proposed the cyclic universe model. For the cyclic model, the universe is born and dies infinite times. There isn't a single universe, but infinite. Each universe is between a Big Bang and the next cycle. The universe expands and contracts, so that it starts with a Big Bang and ends with a new Big Bang. Whenever a universe dies, a new one begins.
Universes bubble: new universes are born of others that already exist. A new universe can be born at any time and place of the Cosmos. There is an inflation of space, such as that created our universe, and a new universe begins inside another.
Multiverse: is a consequence of the laws of probability in quantum mechanics. It proposes that if time is infinite, all odds just to be satisfied. Each probability is fulfilled in a parallel universe. So 'I' would have parallel universes with exactly identical and parallel universes with another completely different "I". It is a difficult idea.

Membranes or Branes universe
String theory is a cyclic model called "Branes universe". According to this model, each universe is a membrane or membrane. There are endless branes. The branes vibrate and sometimes collide. When two branes collide a new Big Bang and is born another universe.Parallel universes
The model of parallel universes, there are many universes at the same time. Although there are at the same time, they are independent and it is impossible to move from one to another. Its physical laws are different and some may only have life. The best-known models of parallel universes are universes bubble and the multiverse.Universes bubble: new universes are born of others that already exist.
