Here is an excript from Serge Brunier's Majestic Universe: ''An object indicates its existance by the radiation it emits, which, like electromagnetic radiation, propagates at 300,000 km/s. At every moment, our vision of the world is thus limited by a horizon, which is expanding, ever since the big bang at 300,000 km/s. So, one second after the big bang, the horizon for any individual point in the universe lay at a distance of 300,000 km. This cosmic horizon moves infinitly faster than the expansion of the universe. Which is another way of saying that with every second that passes new regions of the universe appear that were never connected in the past. Yet present day cosmic structures show that there must have been an extraordinary homogeneity in the past, that cannot be expressed in equations. How could different regions of the universe, never in conatct with one another, 'pass the word' to one another so that their characteristics were exactly the same at the instant their cosmic horizons coincided, and they came in contact? Why also was cosmologogical background radiation emmited when the universe was 300,000 years old?'' I was wondering what you smart guys had to say about this and if you could explain it a little more simlpy.Please Register or Log in to view the hidden image!
