Profile:
On my spare time I enjoy hiking in woods and fields. Love to paint and take photographs. Read a lot, both fiction and non-fiction (considered as well-informed).

Through all my life I have been interested in Swedish cultural history, and have visited many ancient monuments during holidays, as Ales' stones in Scania, the Viking town on Birka, Uppsala burial mounds, the Ottar barrow, and several ancient remains on Gotland.

If the Universe has a limit, what is outside it? I think many of us have asked ourselves the same question. However, most cosmologists regard this question as impossible to answer. Even so, the Universe has in fact a limit; it is defined as what in principle can be observed. In other words, what is determined by the age and inflation of the Universe? Outside our Universe it is infinite room for other Universes. Furthermore, that the room is indeed infinite has been proven by a detailed analysis of the cosmic background radiation. (In fact, the Universe is completely flat!) Now, can it be other Universes? Yes, very probably says, for example, the Swedish cosmologist Max Tegmark. He justifies this statement with the fact that life is dependent on an extreme fine tuning of the natural laws, with a series of natural constants with definite values. If any of these constants would change even with a fraction, the result would be a Universe where life couldn't exist. The implication is, according to Tegmark, that there is a vast number of Universes, out there, with different values on the natural constants (He resembles this with bubbles of Universes in an infinite room, where all Universes originated from their own Big Bangs), and we can only live in that particular Universe which has the right values on those constants.

However, how can the room be infinite? Well, compare with filling up a number with a vast number of decimal digits, for example for pi. The room is created in a similar way through the objects extending it, but is still infinite (as the number of decimals for pi is infinite).
