But if you really know that it stops there and that's it, and you have definite proof for it, sir, you are one rich man.

And NASA supports my theory: "We now know that the universe is flat with only a 0.5% margin of error. This suggests that the Universe is infinite in extent; however, since the Universe has a finite age, we can only observe a finite volume of the Universe. All we can truly conclude is that the Universe is much larger than the volume we can directly observe."
