As an aspiring astrophysicist, I know a thing or two about space. I also know that space is super cool and almost everyone I've ever talked to wants to learn more about it. This is a technique of studying I do with friends and family, as by teaching something that I know, if better cements that concept into my brain.
Fair warning: I don't know everything, and I will let you know if what you're asking is out of my grasp. But I'm pretty good, so fire away.

So far, using gravitational lensing, and the HST, we have seen images of galaxies as they were less than half a billion years after the so called Big Bang. Of course, the further we see into space, the further are looking into the past. But as the Universe has a finite age, is it reasonable to say there is only so far we can possibly see into the observable Universe? If so, what do you think you will see, at the limit?
