As far as we seems to know, right now, the universe -as we know it- is about 13,7 billion years old. That is becausewe have “seen” light which has used this amount of time reaching the earth. These are the farest objects we have “seen” in the observable universe.

Oh, the observable universe is about 46,5 billion light years from the earth. In all directions.

Most of the universe consist of mysterious black matter and black energy. It’s out there, but we don’t know what it is.
Although, we know that our familiar concept of the universe (the observable universe) contains about 80 billion galaxies.
But mathematical discoveries and telescopic image analysis suggest that our conecept of the universe are wrong.
According to physic we live in a world of no less than 11 dimensions. Maybe more. According to string theory we are living in these dimensions simultanously.

The WMPA satelitte and the Hubble telescope have revealed clues that might suggest that we are not living in a universe, but in a “multiverse”.
That the big bang is constantly happening. Universes are constantly born as pieces of a jellyfish. When membrane-like bubbles of universes touch each other they create a big bang, a trigger into a whole new universe. In a endless see of other universes.

That means that space and time have existed before the big bang. And perhaps the parallell universes exist just a millimeter beyond us. Maybe gravitation are just weak signals leaking out of another universe into ours. Perhaps even you exist in a modified version in a parallell universe.

This sounds spooky or childish, but is in fact possibilities if the universe is just a part of a multiverse, which we maybe will know more about in the coming years with better and even more sophisticated eyes in space.
