The logical way to start this blog is with an article about the great beginning.
As we all know the we all live in this infinite universe that must have had a beginning. That beginning got the name of "The Big Bang" because the event was like a great explosion. Since then our universe started to expand and it's still expanding.
Now scientist have two big questions. The first is how did the universe look moments after the big bang (CERN Large Hadron Collider experiments)? The second question, and the most recent one is why did "The Big Bang" happened in the first place and what was before it? From here on we enter on the land of theoretical physics, strings, space-time fabric, dark mater, black energy and parallel universes.
The first one to put the second question was none other than Stephen Hawking which also provided an answer, giving birth to the "String Theory". Another scientist said that the Universe had no beginning, but it's pulsating. He's opinion is that the Universe is expanding until a certain limit and then it will shrink until it reaches the size it was just before the "last Big Bang". After that it will "explode" again, giving birth to another big bang and so on.
In my opinion any of these theories can be true, but I think that the string theory , along with the 11 dimensions that it implies is truthful because it's giving meaning to the time traveling by canceling the "Grandfather paradox".
So, if there are an infinite number of universes (parallel realities) then, a big bang is when two of them collide (they are seen as "Brains" shorten from membranes)....to be continued.....
