Comments on: Hubble and Spitzer find most distant galaxy http://blogs.discovermagazine.com/badastronomy/2008/02/12/hubble-and-spitzer-find-most-distant-galaxy/ I am an astronomer, writer, and skeptic. I likes reality the way it is, and I aims to keep it that way. My real name is Phil Plait, and I run the Bad Astronomy blog.

How did we get here 12b years before the light? Imagine how embarrassing it must be for that light (the fastest thing in the universe) to spend 12b years traveling across space and finding out we've been waiting for all that time. By the way, the accelleration of the expansion of the universe is probably caused by a massive gravitational "pull"eminating from beyond the "bubble" in which the universe is located. the closer we get to it the faster we are drawn toward it. Makes sense to me. If the universe is 14b years old, and we see galaxies/stars that are over 12b lightyears away, how did we get here so fast? How did we get here 12b years before the light?

For some reason we assume without any frame of reference that it was infinitely small when it may well have been both at once (think about it, if space did not yet exist then neither did size) So what does that make the current universe, finite or infinite? And by the way, despite the previous poor attempts at satire, religious people do wonder at the science behind all of this and marvel at the beauty of the universe. And while I am at it, let me ask this question: If space is expanding, and it certainly seems to be doing just that, then is it not also expanding on the microscopic level. Would that makes Planck's constant actually a variable, varying by the rate of expansion. Would those of you not laughing too hard take at stab at this.

If it has a red shift it is moving away from us, if it has a blue shift it is moving toward us.
