It is infinite

Well anything like that is incredibly hard to explain. And anything anyone tells you is not 100% perfect, because how do they know? There are some common theories though, and the one I find to make most sense is; That if the universe is not infinite then it is definetly growing. There is a theorem called Red Shift Blue Shift, which deals with the speed of light in certain conditions. First off, you know that red light travels at a different speed than blue light, correct? Blue light has a wave length of roughly 700 Nm (nanometers), whereas that of Red light is a bit shorter. Now here's the tricky part, Astronomers look at stars, agreed? One night they look at one and they see that it has a Redish tint to it. They come back to the same star one year later and notice it has acquired a Blueish tint. So if the wavelength of the Red were shorter and the star is getting farther away the wavelengths of the stars light must be getting stretched causing the light to travel at a different speed and frequency. This might be hard to understand, but I do not believe the universe is infinite, rather that it is growing. Because from the big bang the universe was created, and it would take an infinite amount of time to create something infinite. Therefore it makes sense that the universe is still expanding and growing.

I believe that the universe that we live in is infinite. I would also like to mention that this statement may not say what you think it says. There are different kinds of infinite sets. For instance, there is countably infinite (the set of integers) and there is uncountably infinite (the number of points on a finite line segment). One way that we measure these different infinite (transfinite) sets is with a measure called cardinality. Consider that the number of points in any finite sphere with a volume greater than zero is infinite. Is this a case of an infinite space existing within finite boundaries? I am not sure. I am sure that the universe is infinite but I am also sure that I am not aware of everything that implies.

as i understand it, the general scientific consensus is that the universe is finite yet has no boundaries. it has no edge and no center. it may be something like the two dimensional surface of a sphere. nothing inside or outside the sphere exists for the surface. space-time itself may have originated in the big bang. the big bang was the whole universe, and everywhere in the universe was once the big bang.

without a doubt its infinite.its continuasly expanding, there isnt enough matter or gravity in the universe to slow the expansion down or to make it collapse. dark mater is what holds or galaxies together.... but thats a different issue.

Why yes, me....Only because its expanding though
