Okay, so people say the universe is expanding like a 3 dimensional balloon. Now in the 2 dimensional balloon representation, it is curved so you will eventually end up in the same spot if you went in a "straight line" across its surface, like a planet. People also say that the universe most likely isn't curved in on itself via the 4th dimension. Now i seriously doubt that our milky way just happens to be in the "middle" of the universe so when we see the Hubble deep field and all of those distant galaxies, I'm willing to bet that if we were in one of those distant galaxies, we too would see other galaxies all around us with a new cosmic horizon surpassing our current one in the milky way, right? Which means that the universe is either curved in on itself or infinite, right?
