<font color="yellow">Do you think the reason that the universe is loosing heat because the whole universe is expanding not that it actually loosing heat. It just that its the same heat just has a tuff time of geting to all of the empty space, since of the expansion in deep space. Like a room with a match if you put a match in your hand it will burn your hand, but if you put the same match with the same heat in a bigger room you wont feel the heat. Well anyway thats my question or statement.</font><br /><br />If you have a light collecting area of a sphere of about<br /><br />4*pi*(13.7 billion light years)^2<br />which is<br />2.3585821 * 10^21 square light years<br /><br />Then you could concievably collect all of the light that is being emitted from the galaxies.<br /><br />However, the big bang theory is more complicated than that, with the furthest "comoving" distance being much greater than 30 billion light years.<br /><br />The only thing I could imagine with such a huge "gross" surface area would be the surface area of black holes which are a billions of times of wider and a billion times heavier than the largest known quasars - that is to say billions of light years across. IF there are no such objects (objects which run against the cosmological prinicple).... the universe will die of heat.<br /><br />It is more likely, by chance, that we live in a eternal universe. The simple matter of probability states that we are infinitely more likely to live in an eternal universe than in one that is temporary and finite, since the eternal universe will have an infinite number of births where as the finite mortal one will have a finite number of births.<br /><br />For the universe to be infinite, it must follow that the cosmological principle be wrong and that all the radiation and particulate matter emitted by smaller objects (atoms and planets) is bounded by yet larger objects (stars, blackholes, galaxies, clusters, and, by requirement, <i>the larger yet</i>).
