The Hitchhiker's Guide to the Galaxy: rummet og livet

The universe is VERY big, and almost indefinable. The space, I think, is IN the universe, and it is a subcategory to the universe. The space consists of all the planets, stars etc.

I think it’s hard to define what the space and the universe really is. But what I really think of in my mind, when I hear the word space and universe is: “The Big Bang”.

And in the Big Bang, the universe and space started extending by developing nuclearcore, and afterwards the universe started a process called: “nukleosynthesis”. After the synthesis the universe mainly contained hydrogen(H) and helium(He).

After a lot of years some more atoms arised, and the universe extended even more. So all the reactions and synthesis started up, after the big bang, and I believe that this was the way that the Universe appeared.

I don’t believe that some kind of holy man like Jesus came up, and created the “Universe”, “The Space” and “The World” etc. I would incline to a scientific theory that has an explanation, but in the end, I don’t think any of the things are 100 % correct. But who cares. What could space travel lead to? Is it worth the cost?
