It is speculated on currently if this universe is all the universe or only plus that if it expands or if it contracts and that at some cosmic moment it will be able to meet with others in the same conditions or not. what &#039 would originate from this; ' shock universal' ' not yet it can at least be imagined by the mind of the human being. Others imagine that, if the Universe is in constant expansion, will arrive one ' ' momento' ' finite where it will have a return to the initial singularity, with a great condensation. It would be as a pulse, expansion-condensation, one distole ' ' seguida' ' of one sstole. In this in case that, time and space you are welcome would mean, therefore, this phenomenon would be, as it is today, imensurvel. How many times this already would have happened? We would be living deeply its first distole (expansion)? Or, in contrast, the universe already would be in the compressiva phase, returning the point ' ' inicial' '? In this in case that, nothing of eternity and nor of the infinite. , As they think some understood, infinite, but perhaps not perpetual, the limited infinite (for the start). What we know after all? One knows that when has many explanations, theories, for one alone fact, in the great majority of the times none of them is certain completely.

That is fact. In the confines of this universe it exists, among others of some largenesses, a called galaxy By Lactea. In this, some solar systems are discovered the all instant for the astronomers and other similar planets to the Land and of others not yet definitively elucidated, the all moment are announced in the media. I can imagine now that we live in a planet where, in contrast of what if it passes there it are, we only find the conditions of survival for the corporal instrument that characterizes each one of the beings livings creature that had been developed here and that still they are in full vital evolution.
